The brake caliper can be deserved to call one of the most important and important elements of the vehicle. The suitability and handling of the entire car, as well as the safety of the driver and passengers, directly depends on its performance. The brake caliper is considered one of the most advanced and common parts in the automotive industry. There is a big competition among brake calipers manufacturers and each manufacturer strives to make this item as reliable as possible.

Brake caliper, its device and principle of operation

Nowadays, you can select the two most relevant, perfect and common brake calipers systems:

1. Enter fixed design.

2. Having a floating head.

Caliper with fixed design were created long before the birth of a floating head caliper. Such a mechanism is distinguished by the presence of a metal case and cylinders, which are opposite each other and are located near the brake disc. As a result of fastening the housing on the suspension, it consists in real-life. During the driver pressing the pedal, the pad influenced on the disk. When they are not used, they are fixed by the specialized spring at an optimal distance. For the instantage of the pads, by means of a special system, the brake fluid arrives to the cylinders.

As a result of the use of several cylinders, brake calipers have become widespread. They differed in high reliability of disc brakes and were used most often on high-speed and heavy vehicles.

Floating spice caliper is distinguished by a fixed position of one of the pads. The construct of the caliper includes a bracket. Directly the housing is mounted on the inside of the wheels. There is a piston in the case. When you press the motorist on the pedal, with the help of a piston, the shoe is pressed against the brake disc. The second shoe begins to move after and passes through special fingers.

This type of brake caliper is relatively few. In addition, it is quite easy to serve or repass. A floating head caliper or a bracket is small and use it in low-cost and small cars.

Brake calipers care and maintenance

To avoid faults and subsequent repairs, the motorist must regularly inspect and adjust the braking caliper, as well as, constantly maintain the brake system is good. It is very important to know how and how often it is necessary to adjust the caliper and its inspection.

1. Visually examine the entire system must be at least once a month. Particular attention is required to turn into fluids. If you found the leakage at the contact site, it should be fixed instantly. With timely prevention of faults, you will protect yourself on the road and you can avoid the failure of the entire system.

2. With regular and permanent operation of the car, it is necessary to completely merge and change to a new brake fluid once again. Over time, the brake fluid attracts outsider moisture from the environment, which does not affect the brake system and the brakes are able to lose their effectiveness.

3. In the manufacture of brake pads, manufacturers try to make them as high quality and safe as possible, as well as creating them in such a way that the buyer would receive a signal that the pads were worn. If the motorist wants to replace the pad on his own, he should look at what extent they are worn out. With partial wear, it is necessary to adjust the sleeve and replace the brake fluid.

How to remove the brake caliper, work stages

Remove the brake caliper preferably on the lift. What to remove it correctly, you need to stick to a number of certain actions. We will give an example of removing the caliper on domestic car models.

1. Prevented such work, it is necessary to raise the vehicle using the lift. If for various reasons, raise the car is completely impossible, you can use the jack.

2. Then, you need to take a wrench and unscrew the bolt on which the brake hose bracket brake brake device is attached. After the end of this process, it is desirable to remove the bracket that it would be more convenient to work.

3. When the bracket is removed, you will see a bolt that holds the brake hose. Such a bolt should be turned out, and the hose is removed.

4. Immediately, after removing the brake hose, a liquid will be rejected from the recess. Prevent the leakage can be closed with a bolt hole, which is suitable in diameter and size.

5. Next, it is necessary to remove the brake pads, so that they would not interfere and work is convenient.

6. Now, you must unscrew the bolts in the mounting of the brake device. After that, flexing the locking plates.

7. Do not forget that these most bolts are very different between themselves and screw them up. It is necessary for the hole where they were withdrawn.

8. Well, finally, we remove the brake caliper itself.

Caliper brake front, repair with your own hands, work step in stages

If malfunctions occur in the front brake caliper, it is necessary to repair it. It is necessary to act in this order:

1. After the described process and brake caliper was produced, it is necessary to remove the case from it.

2. From the caliper, it is necessary to completely drain the brake fluid.

3. After draining the liquid, you need to get an old cuff and clean the surface and the groove of its location.

4. A new cuff is very important to install clean hands.

5. Next, it is necessary to lubricate the surface of the cuff with a special fluid.

6. Piston, which is available, also need to be treated with specialized fluid.

7. Then, it is required to mount the piston back. For this, it must be slowly swinging and inserting, without applying great efforts.

8. When the piston has entered partially, it is necessary to wear a special case, which is called the boot.

9. After the boot is dressed, make sure that he sat down in the right way.

10. Then, the piston is completely and start collecting the front caliper.

11. The surface for which the pads moves, clean from corrosion, dust and diverse dirt.

12. It is important not to damage the thread none of the compounds.

13. Next, it is necessary to build a brake caliper in the order in which it was disassembled.

14. Also, when assembling it is necessary to clean each element of the mechanism from rust.

15. In addition, it is desirable to wash the brake fluid from the surface of the caliper.

After the caliper is assembled, the motorist should be tested how the brake system works. If necessary, fragile the brake fluid. At the end of the process, professionals advise a test trip and determine the brake response. To accurately determine, make the assembly and repair of the caliper on both sides. Rear caliper repair is carried out along the same technology.

Rear caliper, do-it-yourself repair, stages

When purchasing a new caliper, it is advisable to trust the original manufacturer. However, if you buy the original do not allow finance, you can purchase low-cost counterparts. Replace the rear caliper is needed using end keys.

1. Beginning, raise the desired wheel or the entire car using the jack.

2. Then, it is necessary to remove the wheel entirely.

3. Next, disconnect the tube and drain the brake fluid from the caliper.

4. The next step is to remove the broken caliper.

5. Now, clean and process all contacts and attachments, which we mount a new caliper.

6. After that, it is necessary to twist and collect the braking system.

7. Then, should be attached to the brake fluid.

8. Testing brakes. If everything works, it means that the replacement was made correctly.

If when the vehicle is driving, you can hear a characteristic embossed, screech or whistle brakes, this indicates the required repair.
