Caliper for VAZ 2114 - repair, replacement, how to choose a brake caliper

A brake caliper for a VAZ 2109-2115 family costs on average from 1,610 to 4,270 rubles . The cost is influenced by the brand, as well as the quality of the components used, which is reflected in the mileage without fogging and the passage of brake fluid through the piston body.

Since brakes are a key vehicle system, the need for their repair and routine maintenance is constantly increasing. The efficiency of the caliper lies not only in the installation of new pads and discs, but also in the ability to optimally act on large and small cylinders with a force of 137 kg . At the same time, at the base of the beginning of the useful stroke of the piston, where the sealing ring is located, there should be no brake leaks liquids.

When buying a caliper for the front brakes, it is important to pay attention not only to the price, but also to its material support. Some manufacturers, when creating a kit, take into account the need to provide anti-squeak lubricant, spare piston boots, retaining rings, cotter pins and return springs.

Repairing a caliper whose pistons have corrosion on the top is not possible. The use of repair kits also cannot guarantee full results. It is best to buy a new caliper assembly, thereby eliminating the piston biting to the point of breaking.

What does the price depend on?

In addition to the brand, the following product parameters are involved in determining the consumer price:

• Total area of ​​the brake wheel cylinder.
• Fixed caliper dimensions with fixed mounting holes (standard caliper fits 13″ stamped wheel rim).
• Dimensions of the movable bracket.
• Material of guide pins for movable bracket.
• Locking plate material.

The caliper for VAZ 2109, 2110, 2114, 2115 has a single-piston design , therefore it is the cheapest in its class. Among the additional pricing factors it is worth noting:

1. Availability of a brake hose (reinforced, regular).
2. Implementation of a casing-channel for laying hoses.
3. Availability of spare bolts securing the working cylinder to the movable bracket.

Positive qualities of rear disc brakes

Yes, the main advantage is increased security. The braking distance is reduced, and it does not depend on the weather. The operation of the node is stable, the weather does not affect it in any way. For example, when it rains, drum brakes become ineffective and the braking distance increases. This is not observed when using disk drives.

Overheating is not a problem for disk structures. For example, when braking at high speeds, the fluid in the system heats up due to high friction force. The drum and pads can heat up almost red hot – up to 600 degrees. As a result, the pedal fails and braking efficiency deteriorates significantly. You'll never feel that way with disc brakes. Their device is simple and reliable, so you don’t have to worry about safety.

Types of installed calipers and their prices

The same caliper is installed on a given family of cars, with the exception of the index in its marking, indicating the model of the vehicle body. Otherwise, these are identical brake devices that have a single-piston design independent of the fixed caliper. A similar modernization took place after 2001, and the last half calipers with 4 pistons were installed on the VAZ 2108.

The cost of a caliper for a VAZ 2109, 2110, 2114, 2115 can be as follows, based on its condition:

• New – 1,610-4,270 rub .
• Used – 700-1,980 rub .
• Refurbished (restoration using original components) – 1,420-2,190 rubles .

Tuning VAZ-2114

VAZ-2114 is a fairly recent model that replaced the famous nine. The base of the cars is the same, even such little things as taillights cost the same. But you can significantly improve the car only on your own.

It is worth noting that the Lada Kalina is the first model on which disc brakes are installed on the rear axle from the factory. And it should also be mentioned that you make all changes to your car entirely at your own peril and risk. Intervention or modification of the design, steering, or braking system is punishable by removal of license plates and prohibition of operation of the vehicle. But if this doesn't scare you, you can continue reading.

Examples of prices for current items

When buying a caliper for a VAZ 2109-2115, you can operate with the available amount, since there are quite a lot of good quality analogues to choose from, namely:

• Caliper assembly, R13 TRIALLI – RUB 1,880 .
• ATE assembled with a ventilated moving bracket – RUB 2,480 .
• LUCAS with an extended hose (without adapter) – RUB 4,050 .
• LADA (standard set for R13 wheel) – 4,270 rubles .

The choice of calipers is represented by more than 17 analogues, 2 original brands and 3 brands operating under AvtoVAZ license. Consequently, the price may change based on the financial policy of the manufacturer, as well as the final cost of the caliper.

Where and how to buy?

You can buy a caliper at any auto store that specializes in selling components for domestically produced cars. As a rule, in such stores all goods are in stock. You can select a suitable caliper either by writing out its markings, or rather the final index of the last 5 digits, or by providing the seller with a faulty caliper (the weight of the product is only 2.17 kg). Approximately once every 3 years, the suspension of cars of the 2109-2115 family was updated, therefore, the location of the mating threaded seats (mounting bolts) may vary slightly.

New ventilated brake discs are compatible with all mentioned calipers for VAZ 2109, 2110, 2114, 2115. The installation is fully consistent with original components.

Bleeding the brakes

After all the work has been carried out, it is necessary to perform bleeding - getting rid of air in the system. This is essential to improve operational efficiency. And once you’ve started upgrading, don’t forget to change all the components that have been serving for a long time. Replace hoses, front pads, VAZ-2114 vacuum brake booster, master cylinder. As for the fluid, it should be changed approximately every two years. Briefly, the pumping procedure looks like this:

1. Pour liquid into the expansion tank.
2. Bleed the right rear caliper.
3. Check the fluid level and add if necessary.
4. Bleed the left rear caliper.
5. Repeat step 3.
6. Bleed the right front caliper.
7. Follow step 3.
8. Bleed the front left caliper last.

Here's how to bleed the VAZ 2114 brakes correctly, the essence of the procedure is to go from the farthest to the nearest caliper (relative to the main brake cylinder).

How to remove/install calipers on a VAZ 2115

It is quite rare to remove or install front brake calipers on a VAZ-2115, and even less often to replace or repair them. But there are incidents when the clamping bracket bolts rust so badly that they simply break off when turned. You have to buy a new caliper and replace it. In order not to overpay at a service station, you can do the work yourself.

We will need:

• head at 19;
• crank and ratchet handle;
• extension;
• split brake pipe wrench.

Let us remind you that quite recently we told you how to replace the solenoid relay on a VAZ 2115 with your own hands. The retractor relay is the main cause of a broken starter on a car. I recommend checking it out.

Procedure:

1. After the car is jacked up and the front wheel is removed, it is necessary to spray the caliper mounting bolts with penetrating lubricant from the reverse side. Then you should unscrew the brake hose, as shown in the photo below.

2. Lift it up and secure it so that the brake fluid does not leak out of the reservoir. Now you can unscrew the two caliper mounting bolts.

3. When the force is not so great, it is better to use a ratchet.

4. After this, you can lift the caliper assembly with pads up, since nothing else holds it.

5. If you are changing the entire assembly, then buy a new mechanism and install it in the reverse order.

After this, you will have to bleed the brakes, as air may form in the system, which will lead to poor braking.

Disassembling the unit

Before disassembling the entire brake system on the rear axle, the fluid must be drained. To do this, unscrew the bleeder fittings located on the calipers. Therefore, in the future you will have to pump it. The initial work looks like this:

1. Loosen the cable and move the pads together. Unscrew the guide pins that secure the drum to the wheel hub. If you cannot remove the drum easily, generously coat the seat with WD-40 penetrating lubricant. It should always be at hand when carrying out such repairs. Even more - in advance (about half an hour) all threaded connections should be treated with this liquid.
2. Remove the springs using a flathead screwdriver and remove the spacer bar. By disconnecting the handbrake cable, you can completely dismantle the old, now unnecessary, pads.

Please note that now you will not have a handbrake (unless you install a hydraulic one). Therefore, absolutely all components that in one way or another relate to the cable, including it, can be removed. Now we need to talk about installation.

Rear brake pads for VAZ 2114 how to choose

If you are wondering which rear brake pads for the VAZ 2114 you should choose, I recommend that you familiarize yourself with this table of the most successful brands of pad manufacturers for the VAZ 2114.

Installation of disc brakes

The location of the mechanism support can be either in front or behind the rear wheel axis. It will work in any case, but if you install it at the back, the efficiency becomes a little higher. Next, your task is to correctly connect the hub to the faceplate. Pay attention to defects, even the most minor ones. If there are deficiencies, carry out the joining work again.

Straighten the corners of the rear beam. Without this, it will not be possible to install the rear hub. It is most convenient to carry out straightening using a grinder. To install the disc brake caliper, you need to do a few more steps:

1. Mount the brackets on the faceplate.
2. Attach the brake disc to the wheel hub.
3. Install spacers at the contact points to increase reliability.
4. Fix the faceplates and brackets.
5. Seal the brake mechanism.
6. Secure the caliper and install the brake pads.

That's all, in general, as you can see, the work is not difficult. But you should be careful during installation, use only new elements, especially bolts. It is unacceptable to use bolts that have been used. Their carvings are already deformed, although this is not visible to the naked eye.

Rear wheel brake

Rear wheel brake on VAZ 2114

1. Hub nut
2. Hub flange. The brake drum is attached to it
3. Lower tension spring
4. Left pad
5. Thrust spring
6. Cylinder
7. Upper tension spring
8. Guide bar
9. Eccentric
10. Right pad
11. Pad cover

Tip: when driving through deep puddles or fording a river, the brakes get wet. This dramatically reduces braking efficiency. Immediately after overcoming a water obstacle on a straight section and at low speed, brake several times. The pad linings, discs and drums will become hot and dry. The system's efficiency will be restored.

In general, the braking system of the VAZ-2114 is simple and reliable. For a person who has experience driving cars of other brands, servicing it on a “fourteen” will not be a problem. But even those drivers who got behind the wheel of a car for the first time can easily understand the operating principle and operating features of the VAZ-2114 brake system. But remember: it is better to service the brake system at warranty service stations from experienced technicians.

Brake device

The brake system of the VAZ 2114, the diagram of which is given below, is divided into hydraulic, which provides braking while driving, and parking.

The first includes such components as:

• brake structures of front and rear wheels;
• main hydraulic cylinder;
• pipelines;
• expansion tank;
• vacuum booster;
• pressure control levers;
• pedal;
• brake hose

The entire hydraulic brake system is divided into 2 connected, but working independently of each other, circuits located diagonally.

The device of the brake system of the VAZ 2114

The first circuit is responsible for stopping the front left and rear right wheels, and the second circuit is responsible for stopping the front right and rear left wheels. This is necessary so that if the pressure drops (for example, as a result of a leak) in one of them, the second circuit remains operational and allows braking.

In turn, stopping the car itself occurs due to the action of the front and rear brake structures on the wheels, which are somewhat different in structure.

The front includes components such as:

• brake discs;
• caliper;
• pads;
• cylinder and piston;
• O-rings;
• protective casing;
• guide pins;
• finger guards.

Front brake

In turn, the rear brake structure consists of:

• hubs;
• hub fasteners;
• brake pads;
• tension springs;
• direction springs;
• wheel cylinder;
• parking brake lever finger;
• expansion bar;
• hand brake lever;
• protective casing of the brake mechanism.

Rear brake mechanism

As you can see, the rear brake structure is somewhat more complex than the front one. This is due to the fact that it is responsible for the operation of not only the main brake system, but also for the operation of the handbrake.

The latter consists of such elements as:

• lever equipped with a locking button;
• cable;
• equalizer;
• adjusting nut;
• locknuts;
• protective cover.

Parking brake VAZ 2114

The handbrake cable is its weakest link and requires regular inspection. If creases, delaminations and other damage are found on its surface, it should be replaced immediately.

As for hydraulic brakes, the brake pads are subject to the greatest wear, the degree of wear of which should also be periodically checked.

Basic information

Since the release of the first car at the car plant in Tolyatti, and this was the Zhiguli-2101 model, popularly nicknamed the “penny”, almost to this day the brake system diagram of all cars has remained unchanged. Discs were placed in front, and drums in the back. This is logical, since the main load during braking falls on the front ones.

Of course, this scheme is much more effective than the GAZ-24, which has drums in a circle. Because it’s no secret that disc brake pads grip much better, and the distance to stop is correspondingly much shorter.
