First of all, we should know that most of the original brake calipers are basically single piston floating calipers, while the general modified brake calipers are multi piston fixed calipers. After all, the surface area of multi piston must be higher than that of single piston, so the braking effect of multi piston fixed caliper must be better than that of single piston floating brake caliper. Therefore, it is necessary to modify the brake caliper to improve the braking performance of the original vehicle. It can be known from the invention of "Pascal hydraulic principle" - changing the piston area of the brake caliper can effectively increase the force. Therefore, as long as the diameter of the caliper piston is increased, the braking force can be improved.

The brake caliper can make the brake no longer weak, shorten the braking distance of the vehicle, improve the braking performance and ensure driving safety. The caliper is equipped with dust cover to prevent impurities from damaging the piston. In addition, it is also equipped with anti noise shrapnel to fix the brake skin to reduce the noise in daily use.

What's the use of calipers

Brake caliper is a caliper device with the functions of decelerating, stopping or maintaining the stopped state of moving wheels. It is generally used in disc brake system. The disc brake is composed of a brake oil pump, a brake disc connected to the wheel and a brake caliper on the disc. When braking, the high-pressure brake oil pushes the piston in the caliper and presses the brake shoes against the brake disc, resulting in braking effect.

Changing the brake caliper can make the brake no longer weak, which depends on the piston of the brake caliper. In general, the calipers of vehicles delivered from the original factory are configured with one-way single piston. The main disadvantage of this design is that under the condition of fierce braking, the caliper will bend to both sides and deform. In addition to the advantages of good overall rigidity, strong clamping force, average force and rapid response, the body made of aluminum alloy can also provide lightweight and heat dissipation effect better than the original cast iron, which can effectively reduce the weight of large-size disc group and reduce the working temperature of brake oil.

Calipers mainly use pistons to make the brake pads clamp the brake discs. Most ordinary cars use single pistons, while sports RV / performance vehicles will be upgraded to double pistons to provide better braking performance. More than 4 pistons are usually called "abalone". Typical examples are evolution and WRX STI. The main internal components of the caliper can be divided into piston, piston oil barrier and dust barrier. As for other details, ray Xiaobian won't mention them. When working, the piston and caliper will rub against each other. When the plastic parts reach the life cycle, there will be the problem of hardening / insufficient sealing. When impurities are mixed into the interior, there will be rust. In the long run, the piston will not operate normally, and finally there will be blockage.

Once the piston is blocked, it means it can not operate normally. Firstly, it will reduce the braking efficiency. Secondly, because the piston can not complete the telescopic action, the piston is stuck, so that the brake pad can not return to its position, and forces the brake to rub with the brake disc all the time (this possibility is not ruled out). In the long run, it will lead to uneven running in of the brake disc and brake pad, and the cost of changing the disc and brake pad is not cheap, So next time you might as well ask the mechanic to check whether the piston works normally.

It is often repaired every 60000 km, but because few car owners require calipers to be repaired, most car manufacturers rarely provide such services, mainly because of more work and trouble. The process is roughly as follows: remove the caliper, remove the piston, clean, polish the rusty part of the piston, replace the piston seal and other oil traps, reinstall the caliper and piston, and finally eliminate the excess air inside the brake. You can also change the brake oil
