What is brake caliper

The brake caliper is the brake that holds the brake pad to achieve the braking effect after the car steps on the brake. The more pistons in the car caliper, the greater, more stable and more stable the braking force.

Brake caliper is a caliper device with the functions of decelerating, stopping or maintaining the stopped state of moving wheels. It is generally only used in disc brake system.

The working principle of disc brake can be described as a plate. When holding the rotating plate with your thumb and index finger, the plate will also stop rotating. Your thumb and index finger play the role of brake caliper.

The disc brake on the car 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 to press the brake shoe against the brake disc, resulting in braking effect. Disc brake, which is divided into ordinary disc brake and ventilated disc brake. Ventilation disc brake is to reserve a gap between the two brake discs to make the air flow pass through the gap. Some ventilation discs also drill many circular ventilation holes on the disc surface, or cut ventilation slots or prefabricated rectangular ventilation holes on the disc surface. The ventilated disc brake uses the effect of air flow, and its cold and heat effect is better than that of ordinary disc brake. The main advantage of disc brake is that it can brake quickly when braking at high speed, the heat dissipation effect is better than drum brake, the constancy of braking efficiency is good, and it is convenient to install advanced electronic equipment such as ABS.

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 internal main components of the caliper can be divided into piston, piston seal and dust boot. Ray Xiaobian will not mention other details. When working, the piston and caliper will rub against each other. When the plastic parts (seal) 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 the problem of blocking.

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 fluid.
