One of the most important and crucial active safety systems of the car – the brakes. Their health is directly affected literally the life of the driver. Not always the drivers properly service the brake system, and that becomes the cause of many faults. Any defect must be repaired as soon as possible. In this article we will talk about how to use the kit rear brake caliper that included in its composition, and much more.repair kit, brake caliper rear

Some General information

Brake caliper – the main component of the brake system of any car. When the driver presses the brake pedal, the force is transferred to the caliper, which presses the brake pads to the disk. As a result, the system produces a large amount of heat which a given brake fluid. If during braking the vehicle pulls to side or you notice uneven pad wear, it indicates the presence of a fault.

If we are talking about less loaded axle – back, in this case the problem can most often be corrected with a repair kit rear brake caliper. Depending on the brand of car can use different designs. Today popular calipers with fixed structures, and floating caliper.

Fundamental difference

The Fixed design appeared for a long time. These calipers for many vehicles used today. This unit has a metal housing and two pistons which are arranged in parallel, is located between the brake disc and pads. The caliper body is constantly in a stationary state, as it has a hard mount. When the driver presses the brake pedal, then the cylinders are pressed against the pads to the disk. After that they depart from the disc and fixed at a certain distance by a spring. To ensure uniform and simultaneous pressing blocks to the disk on the cylinder is fed brake fluid.

The Key difference of the caliper with a floating head is that one of the pads is in a fixed position, i.e. it is stationary. The caliper is mounted on the inside of the wheel. This design has one piston. When you press on the brake pedal it pushes the pad to the disk, and simultaneously, a second Shoe moving along the guide rails, which provide the holder. The system is more easy to maintain and considered the budget.

About the main fault

Regardless of the type of caliper in its design there are parts that are subjected to increased wear. Pads and rotors we not taken into account, as they are considered consumables. As for the caliper, the return movement of the piston is ensured by the rubber sleeve. When the driver presses the brake pedal, the piston out of the housing and deform the cuff, when the pedal is released, the cuff tends to take its original position, pulling a piston.

Over time, rubber loses its elasticity and crack. This leads not only to the fact that the piston returns to its original position, but also to the occurrence of corrosion. The cuff is also used as a duster, so periodically it needs to change. In this case, you must purchase a repair kit rear brake caliper kit which is a cuff and a semicircle. Now we go on.

Removing brake caliper

The First thing you need poddomkratit car and set wheel chocks. Once you have removed the rear wheel, it is necessary to remove the retaining spring. For its withdrawal it is convenient to use a normal flat head screwdriver. Then try to clean the surface of the caliper, especially the place of fastening of a brake hose. You can use the rust solvent, or popular moisture displacer WD-40. If you plan to replace the brake fluid, then Unscrew the bolt fastening the hose to the caliper body. If the fluid is still fresh, the hose is first necessary to pinch.stroke guides for brake calipers

To the hole is not exposed to water or dirt, it is necessary to screw back the usual suitable for the threaded bolt. Then go to guides. First remove the rubber grommet, and then the key on the 7-mm twisted "fingers." Then push the piston and remove brake disc. You can now perform a complete repair of the brake caliper. This can be done with a minimal amount of tools.

Repair the brake calipers with your hands

First remove the cover from the cylinder. For this to hook it with a flat head screwdriver and contractible. If there is a repair kit rear brake caliper, the rubber band can not regret, as it is not useful. Now take out the piston from housing, this can be done in several ways:

  • If the caliper is still not removed, you need to repeatedly press the brake pedal, the piston itself will fall, and then we need to squeeze the tube;
  • Clamp the body in a vise and "crocodiles" to pull the piston in a circular motion;
  • Squeeze with compressed air.

Now you need to carefully clean the seat cuff. There should be no chipping and rust. If you leave everything as it is, the gum can very quicklyfail, and repair of brake caliper have to be repeated.

Continue the execution of works

Set bellow brake caliper, you only need clean hands. You can slightly lubricate the cuff with brake fluid, then install in the groove. If the cylinder has obvious burrs or other defects that cannot be repaired, you need to install a new one. If on the surface there is rust then remove it. Before installing the piston surface also should be lubricated with brake fluid. Insert the cylinder in the brake caliper into the housing vertically. Slightly shaking and pressing down with your fingers, push it into the caliper.

It is Advisable to check several times as village of the cuff. If its somewhere crushed, or she sat unevenly, you need to set it straight. After everything is done, you can proceed to the next stage.

About carriage guides

Dismantle the bracket of the brake caliper and Unscrew the rails. If they are very stuck, which happens quite often, you must pour the compound WD-40 and wait a bit. Also help in this case can use a long lever.

Now we need to inspect the guides and seats for defects. Remove rust and grease from the fingers, as well as their seats. In some cases, you will need new guides. Before installing it is desirable to replace the rubber bushings, as they are often broken. The guides lubricated with a suitable lubricant, which should eliminate possible rattling. The repair of the caliper may be over. Now let us consider a few important details.caliper brake rear price

About the lubrication of the guides

For this reason quite often, motorists disputes. Some use copper and graphite lubricants, other – with petroleum jelly. But neither the first nor the second option can not be considered correct. The fact is that over time this grease for rails brake calipers-drying, which will lead to jamming of the finger. Good in this is nothing.

With regard to correct lubrication, it is advisable to take synthetic high temperature silicone grease. This paste works effectively in temperatures from -40 up to +290 degrees. As for the copper, graphite and other greases, they are used as antikamnia, but not for guides. Universal lubricant for slideways brake calipers – SLIPKOTE 220-R. It is not consueta over time and does not dry out. Maintain clean fingers and smooth running. The lubricant should be chosen carefully, because if you choose wrong, it could return more costly.

A Little about cost

As for the cost, if you do everything one HUNDRED, on average, for the bulkhead one caliper specialists take from 500 to 2 000 rubles. Of course, much in this case depends on the brand of car. To repair the caliper on vases will be inexpensive, but the "BMW" or "Mercedes" even these petty work will result in a lot of money.brake caliper repair own hands

As for the repair kits, you can find them for any make and model of car via the Internet directories. Today it is the most convenient method of searching for parts, and not too expensive. For example, a kit guide of the rear brake caliper will cost 800 rubles, on the side, plus a set of piston (cuff & ring) – approximately 300 rubles. At the same time, the price of the rear brake caliper is about 3-4 thousand. The difference here is obvious. Moreover, with the described in this article works to be able to handle even by a beginner. For this you will need a minimum of tools and only a few hours time.

Put a new one or repair the old?

In some cases it is impractical to buy repair kits. For example, during twisting of the guide was damaged threaded connection or broken priming fitting. If the cylinder has non-recoverable defects, it is better to buy a new caliper. Of course, you can try to repair the old one, but it will cost as new, so not much point in this.

But if you need to replace only the cuff or guides, it will cost you 1 000. Original brake caliper is not always easy to find. And the price tag is often too high. In this case, you must only buy high-quality analog. Chinese calipers, it is desirable to avoid. Worthy counterparts will cost about 20-30% cheaper than the factory. To the new caliper worked for a long time, it must be maintain every time you change pads or brake disc.

To Summarize

Here we started to grasp how the repair was performed the vehicle's braking system. The most vulnerable part – the calipers. This is due to the fact that they work at high temperature. The day the caliper is going through many cycles of heating/cooling. The greatest danger is sudden braking getting into the water. In this case, can lead the principal parts.bellow, brake caliper

Based on the foregoing, it can be concluded that for normal operation the brake calipers periodically:

  • Inspect for integritypiston boot;
  • Inspect the surface condition of the cylinder;
  • Lubricate the guides;
  • To change the rubber bushing guides;
  • Clean the rust from the places to which brake Shoe goes.

If replacing the rear brake pads runs every 20 000 kilometers, it is through this interval it is necessary to inspect the calipers. In some cases, be quite normal to visual inspection. If you notice any defects, repair them by using the appropriate kit rear brake caliper. Inspection of the front brake system you must perform more often, as it is more loaded. Pads on the front axle wear out on the order faster, as the load is higher. Therefore, you should regularly lubricate the cylinders, guide rails and change the cuffs. Maintaining the brake system in good condition will make the drive safe and comfortable.
