Hi all! A couple of months ago, with about 120k miles. replaced the brake discs because... When braking, a beating appeared and there was a decent amount of output. I decided to install R 14 wheels. To switch from 13th to 14th wheels there are no particular difficulties; you need the disk itself and a pad guide (R 14 caliper bracket from a VAZ 2112). I didn’t bother with the choice of disks, I took the usual “Ladovskie” ones for 945 rubles. per piece, “guides” for 635, caliper guides along with anthers for 40 rubles apiece, lubricant for the guides for 260 and pads (green Ferodo) for 900.

And then to the garage for installation. There were no particular difficulties during the replacement, the old discs came off almost without effort, one had to be hit a little with a hammer. I would like to say hello to AvtoVAZ and their ingenious decision to install bolts not with the usual “17” head, but with a “torx” head, onto which the “block guide” is screwed.

I didn’t have a key or such a head, so I didn’t invent anything so as not to drill out the bolt later. I had to go to the store (fortunately not far from the garage) and buy an “E 12” head

What front brake discs should be installed on the Lada Granta

The front wheels of the Lada Granta are equipped with disc shoe brakes. What makes the pedal informative is that it makes it easy to calculate where to stop.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

The power reserve with original parts can range from 50 to 120 thousand km. But sooner or later the need for replacement arises.

You can divide all supplied spare parts into two main categories: original and analogues. The former are more expensive. But at the same time, their maximum mileage is usually an order of magnitude greater than their analogues. There is multi-stage quality control in production. The downside is the high cost. Sometimes it is 2-3 times more than analogues.

The latter are distinguished by their availability. But not all parts are reliable. It is best to give preference to well-known brands that have proven themselves on the positive side.

You asked: What kind of brake discs are on the Kalina Cross?

Issue price: Front brake discs 2112 ventilated R14 (Euro-sport) (Almetyevsk) - 1900 rubles Front brake pads TRW GDB1446 - 680 rubles. Caliper brackets 2112 - 1200 rub. Total: 3780 rub.

Depending on the configuration, the manufacturer equips Lada cars with different front brakes. We determine which brake discs AvtoVAZ installs on Priora, Granta and Kalina, what is the difference between the front brake mechanisms, and how to very easily improve the brakes without modifications.

Aluminum brake drums

Now they are the most advanced. Why? Yes, they simply weigh little, and manufacturers are trying their best to lighten the weight of the car and, in particular, reduce the load on the axle.

Therefore, this material is now being used more and more often, what other advantages are there:

As I already wrote, this is weight. Aluminum can weigh up to 50% less than the same cast iron version.
Price. Not to say that they were cheaper just like that, after all, they are non-ferrous metal. But due to the mass, the difference in price is quite significant. About 30% cheaper.
Cooling. This is really a big plus, we all know that during prolonged braking, say in the city, the discs and drums literally get hot. Aluminum conducts heat well, meaning it heats up quickly and cools down quickly. Therefore, drums made from it perfectly remove heat and cool quickly enough. Also, you can often see ribs on them, for even greater heat dissipation. It is worth noting that the more the drum heats up, the more effective the brakes decrease, and the pads simply begin to “float”. Cooling saves the situation and efficiency is maintained.
Corrosion and aesthetic appearance. Yes, it should be noted that aluminum practically does not show any signs of rust or other decay. Thus, the outer and inner surfaces always remain clean. It is practical, and also aesthetically pleasing; there is no need to tint or maintain it. This is definitely a plus.

But this system also has disadvantages and they are also significant, let’s take it in order.

The very first disadvantage is greater wear on the disc. Aluminum is a soft metal and therefore wears out quickly. You will change much more often than your opponent.
They get very attached. This material sticks very strongly to the place of attachment, and it is not at all easy to remove them.
Fragility. If you plan to remove them, then you must have special pullers, otherwise there is a high probability of breaking the drum, it is very fragile.
With strong heating, after falling into a puddle, the geometry can change. What will affect the quality of braking?

To be honest, aluminum drums are not as durable a product as, say, cast iron. They really break very easily. Let’s say your rear wheel is stuck, the brake lining is torn off due to high wear, you won’t be able to just remove it and look inside, and if you hit it with a hammer, you’ll simply break the drum. In this regard, the opponent looks much more profitable.

So which is better?

What to choose in the end so as not to make a mistake? Guys, I’ll say that very few people now change aluminum to cast iron in drums or vice versa, most likely the replacement will be with disc brakes (they are really better), and ventilated or even perforated , it has been proven that with these the car brakes 15 - 20% more efficiently.

And the choice between these two, I personally would fall on cast iron, but it needs to be tinted, and it’s heavier, a pair is about 8-10 kilograms, but it’s more reliable and easier to remove. This is my personal opinion.

Cast iron brake drums

Needless to say, this metal is much stronger, but also many times heavier than its opponent. Some manufacturers sacrifice suspension lightweighting and still install cast iron on their cars.

Original

The advantage is exact compliance with the specified dimensions. After purchasing the part, there is no need to adjust it to size or grind it down:

Name	vendor code	Cost per 1 piece, rubles
AvtoVAZ	11180-3501012-10	From 2 thousand rubles

Various manufacturers can be the manufacturer of original parts of this type for cars. But the products are labeled as AvtoVAZ. The quality is up to the mark. A special alloy of cast iron is used. It is allowed to use pads whose friction linings include ceramics.

Acceptable wear of brake discs and when to change them

Each car manufacturer has individual parameters, tolerances, and minimum thickness. Exact details are provided in the instruction manual.

Chevrolet Aveo: 21.5 mm;
Some Nissan, Renault models: 22.0 mm;
VAZ: 17.8 mm for ventilated, 10.8 for non-ventilated.

Few car enthusiasts know about the side wear tolerance - it is 1.0 mm. In practice, there are cases of wear of 2.0 mm or more. This significantly reduces braking efficiency and increases vibration during driving. A disk split can happen at any time, after how many kilometers it’s only a matter of time.

Analogs

The selection of replacements for original parts includes several dozen items. The highest quality and relatively inexpensive are the following:

Name	vendor code	Cost, per 1 piece, rubles
Alnas Sport, ventilated perforated	2112-3501070-03	From 1 thousand rubles
Notched, “PowerDisc”ATE	24.0320-0142.1	From 1.5 thousand rubles
BREMBO MAX	09.8903.75	From 1.2 thousand rubles

Installation of brake pads and discs from a foreign car

Instead of original VAZ brake pads and brake discs, install consumables from a foreign car, for example:

Brembo brake discs (article: 09.8903.75) or ATE Power Disc 14 (article: 24.0320-0142.1);
pads from Fiat (article: 13.0460-2813.2) or BMW (article: 180281).

No modifications or design changes to the brake system are required. The maximum that may be required (for example, for pads from BMW) is to slightly file the caliper brackets.

How are these components better? The discs have an increased contact area of the pads, and the brake pads have an increased contact area (by about 25%). According to reviews from car enthusiasts, the installation of imported brake pads and discs had a positive effect on the performance of the braking system.

What kind of feedback can you leave about such a simple brake tuning? Is it worth switching from R13 to R14 brakes and abandoning original spare parts in favor of imported ones? Let us remind you that other useful tips for improving Lada cars can be found in the “Tuning” category. For example, you can significantly reduce noise in the cabin by installing additional door seals.

Serviceable brake discs of thickness specified by the manufacturer are the key to safety on the road. AvtoVAZ has equipped the Lada Granta with a reliable braking system. This allows you to reduce the likelihood of accidents and avoid emergencies on the road. But over time, the disc wears off and a bead appears on its surface. There is a need for replacement.

What rear brake discs can be installed on the Lada Granta

Despite the fact that this car belongs to the budget class and is one of the cheapest among those sold in the Russian Federation, it is equipped with rear disc brakes. Which implies the need to replace individual components. The price of parts depends on their type, as well as other factors.

It is important to remember: the front and rear discs differ in the diameter of the mounting holes and other parameters. Installation can be done by yourself. The process itself is simple. But it requires some preparation. It is important to decide on a budget for parts in advance. All of them are divided into two main categories - analogues and originals. They differ in price and quality.

There are many types of discs. These are ventilated, with notches and various others. If the driver practices an aggressive driving style, then you should opt for ventilated models. They cool faster. They have more resources. The replacement process is no different from the others.

Granta 4 new size

According to the maintenance regulations, we check the condition of the brake system every 15 thousand km.

We carry out the work on an inspection ditch or overpass.

To check the functionality of the vacuum brake booster when the engine is not running, press the brake pedal 5-6 times and, holding it down, start the engine. If the vacuum booster is working properly, after starting the engine the pedal should move slightly forward. If this does not happen or the braking is not effective enough (you have to press the brake pedal with great force), you need to check the tightness of the connections of the vacuum supply hose to the vacuum booster and the serviceability of the booster itself.

We check the condition of the brake pipes. The tubes must be securely fastened in the holders and have no dents, mechanical damage, deep corrosion, or signs of brake fluid leakage. If necessary, we tighten the connecting fittings or replace faulty parts.

Analogs

The cost of original components is an order of magnitude higher than analogues. Therefore, the choice of many vehicle owners falls on substitutes. The most advantageous offers:

Name	vendor code	Cost, rubles
A.S.P.	2702220	2 thousand rubles. for 1 piece
B.M.	BDV 885	1 thousand rubles for 1 piece.
Hella	8DD355109331	1.6 thousand rubles for 1 piece.

Determining wear and tear at a service station

External signs of brake disc wear are confirmed by removing the wheels and visually inspecting them in a workshop. Nothing can replace the professional approach of masters of their craft:

First of all, they pay attention to the gutter machined by the manufacturers. The disappearance of this groove indicates that the metal has worn down to the control mark, which means it’s time to change it.
The second proven way to measure the layer of a part is to measure its thickness with a caliper. The vehicle operating manual now for many brands indicates the parameters of the permissible thinning norm. In accordance with it, the critical level of wear can be accurately measured.
Deformations of auto parts can be seen with the naked eye. These are cracks, deep scratches and other surface defects. In this case, you can replace the part, otherwise irreparable things may happen. Shallow grooves not exceeding 1 mm, if the metal layer is sufficiently wide, are left by grinding on a machine.
A micrometer is used to measure disk runout. Exceeding the level of 100 microns. implies future vibration while driving. Such indicators will negatively affect the brake mechanism, in particular, will lead to rapid wear of the pads.

All individual moments are difficult to describe, so a qualified approach is needed. Our technicians assess the condition of the car as a whole and, if necessary, replace other parts. Prevention also includes lubricating the caliper, or cleaning it from excessive oiling, and more.

Replacing front brake discs

The replacement algorithm includes the main steps:

it is necessary to remove the wheel and jack up the car;
the old brake pads are removed - to do this, the guide bolts are unscrewed and the caliper is folded back;
The bracket is carefully hung on the suspension, after which you can begin to remove the disk - two nuts are unscrewed;

if for some reason the disk cannot be removed from the bolts, you need to lightly hit it with a hammer from the reverse side;
The new disk is carefully installed.

The nuts are screwed into place. It is advisable to pre-lubricate the threads with graphite lubricant. This will prevent souring. It is advisable to change the pads along with the discs.

If, as a result of wear, a high shoulder has formed on the maximum diameter of the disk, which prevents an accurate measurement, remove the shoulder using a file or other method, or measure the thickness of the disk with a micrometer. We replace a brake disc with defects in the working surfaces or extreme wear.

The degree of wear of the brake pads of the rear wheel is assessed by the condition of the front pad, which wears out faster than the rear one.

Replacing rear brake discs

The algorithm for replacing rear brake discs is as simple as the front ones. The process is similar. Its main stages:

it is necessary to remove the wheel to gain access directly to the part - the car is raised on a jack or lift;

the caliper is removed along with the pads - you can place it side by side or hang it on a spring;
use an open-end wrench to unscrew two nuts;
a new disk is installed.

Assembling the caliper, installing the pads - everything is done in the reverse order. It is necessary to ensure that the thickness of the brake disc corresponds to that specified by the manufacturer. If you have difficulty removing the pads, you need to press in the cylinder with a screwdriver. If difficulties arise with unscrewing threaded connections, you need to use WD-40.

Serviceable brake discs affect the driving comfort, vehicle speed and safety. It is necessary to carry out timely inspection and repair of the main components of the brake system.

I’m thinking of changing to 14th ALNAS (with perforations) do I need to change the calipers?

Change the gasket between the steering wheel and the seat

what's wrong?

Uncle is being insolent...listen, it looks like thirteenth ones. I’ll find out from the mechanic the other day exactly which ones. I want to install 14 discs for myself. But maybe I’ll install Volgov calipers, I don’t know yet.

What does this have to do with brake discs? There are rims and tires of different sizes and the manufacturer usually recommends several sizes, but no one changes the brake discs (wheel hubs)

Actually, I’m asking because the 13th and 14th were installed on the two-wheeler at the same time. But on the grant, I don’t know, there’s nothing in the book about this... I don’t really want to take off the wheel to look at it So Why don’t you be smart since you don’t know anything!

Tires Standard sizes 175/70 R13 175/65 R14 Non-standard sizes 186/60 R14 195/50 R15 185/60 R14

Disks PCD 4×98 DIA 58.6 Standard sizes 5.5 x 14 ET35 Non-standard sizes 5.5 x 14 ET38 6 x 15 ET35 6 x 15 ET38

What does this have to do with it? Don't confuse wheels with brakes!

Good luck learning the materiel

But what’s wrong? If the brake discs are 14th then the 13th calipers need to be changed as I was told. Or is this not so?

but don’t worry, some inadequate felt boots are talking nonsense)) I’m also interested in the standard with automatic transmission, what kind of brake discs they cost, I used to think that from 12, but now I doubt something

But what’s wrong? If the brake discs are 14th then the 13th calipers need to be changed as I was told. Or is this not so?

THEY SAID CORRECTLY TO ME IT SEEMES TO BE 13 I LOOKED AT THE PRIOR THE DISTANCE BETWEEN THE CALIPER AND THE DISC IS MUCH SMALLER AND THE WHEELS ARE THE SAME 14

But what’s wrong? If the brake discs are 14th then the 13th calipers need to be changed as I was told. Or is this not so?

along the way, you still didn’t understand what they told you, maybe you’re a noob, you can install any wheels, at least 13, at least 14, at least 15, and with the tires you can customize yourself

Installing R14 brakes instead of R13

According to the data from the table, you can see that to switch from R13 to R14 brake discs, no modifications are required and the cost of modification is low (buy R14 brake discs and fixed caliper brackets).

Don't forget to check that the rims are at least R14 in diameter. We improve the brakes using the familiar instructions for replacing brake discs.

Most car owners, after installing R14 brake discs, feel a noticeable difference when braking and remain satisfied. However, this is not the limit, the brakes can be made even better!

Which discs are better for Grants in different conditions?

Three different types of brake discs are installed on the Granta. Often users install similar parts from foreign cars to speed up the ride or to save money.

In the city and on the highway

Under normal operating conditions, factory cast iron discs or any other equivalents are suitable. If you have the original 13s and are not enough, change to a 14th size. It's easy to change them, and the car will brake much better.

Remember that you have an inexpensive sedan, not a race car. Do not overheat the brakes and if you drive through a water obstacle in the form of a puddle, dry them by briefly pressing the brake pedal. It doesn't make sense to pay more for ceramics for quiet use.

For lovers of fast driving

If you like to race, think about good brakes. For this purpose, 15-size perforated wheels with grooves or other sports wheels are suitable for the Granta. If you have a passion for this car and you are tuning it, install ceramics. Although it is expensive and needs to be warmed up, it is best suited for sports use.

Off-road

If you want to try a front-wheel drive sedan as a trophy truck, then there is no point in thinking about good brakes. The speed will be comparable to a pedestrian, so you can install cheap brakes or leave standard (factory) ones if they are in good condition. If you're thinking of taking part in a rural rally at high speed, think about good wheels.

If the car is used for fast driving, do not skimp on the brakes. And it’s better not to drive. “Granta” is not intended for this, the security level is also low. The guarantee of your life is impeccable compliance with traffic rules. For fast driving, racing tracks have been built taking into account safety requirements. It is better to practice extreme driving on them.

Where can I see the VIN code?

It's not difficult to do.

The code can be found:

on a plate installed on the central pillar in the lower part near the driver's car seat;
under the hood;
on the threshold of a car;
on the windshield;
under the spare tire;
in vehicle documents.

Once the code is detected it can be read. How to do it?

How does the Lada Granta brake system work?

The working brake system is dual-circuit. This was done to ensure fault tolerance. If one of the circuits malfunctions, the second will perform braking, albeit with less efficiency. The first circuit is located on the front right and left rear wheels, and the second circuit is on the front left and right rear wheels.

The front brake discs on the Lada Granta are ventilated discs. When you press the brake pedal, the pressure in the system increases, the piston moves, pressing the pad against the disc.

To reduce cost, the rear brakes are drum brakes. They have a mechanism for automatically adjusting the gap between the drum and the pads. The disadvantage of this design is instability to moisture and souring of the brake cylinder. Only replacement helps. The Lada Granta Sport uses rear brake discs, but they are not ventilated.

Original or analogue?

This is what AVTOVAZ writes about the original LADA brake discs.

Original brake discs meet high LADA standards and guarantee quality, for this:

Each batch of brake discs undergoes random inspection and checks of the metal structure using special equipment, excluding porosity and other casting defects
The disc is made from high-quality cast iron, which guarantees no warping effect during sudden braking or overheating.
Brake discs undergo high-precision processing to ensure the absence of runout and imbalance
All original LADA spare parts undergo numerous tests confirming the reliability and quality of each part.
