Youdaoplaceholder0 WHAT is the rear brake caliper of a car
The rear brake caliper is an important component of the automotive braking system Its main function is to apply pressure to the brake pads, causing them to rub against the brake discs or brake drums, thereby reducing the vehicle speed .
Working principle
When the brake is applied, the master cylinder generates thrust that pushes the hydraulic oil to the slave cylinder, and the piston inside the slave cylinder starts to move under the hydraulic pressure, thereby pushing the brake pads against the brake disc or brake drum to slow down the vehicle until it stops .
When the brake pedal is released, the brake fluid flows back to the master cylinder and the system returns to its original state, ready for the next braking operation .
Maintenance and care suggestions
The brake caliper is a very important component in the automotive braking system. It has high technical requirements and is directly related to driving safety. Therefore, car owners should attach importance to the maintenance and upkeep of brake calipers. In general, the disc front wheels of a car need to be serviced approximately every 30,000 kilometers, the disc rear wheels approximately every 60,000 kilometers, and the drum brakes approximately every 100,000 kilometers .
In addition, road conditions and driving habits also affect brake caliper wear to varying degrees .
The main function of the rear brake caliper is to transfer the pressure of the hydraulic oil to the brake pads, reducing the speed of the vehicle through the friction between the brake pads and the brake drum (or brake disc) until it stops . Specifically, when the driver steps on the brake pedal, the master cylinder of the brakes generates thrust, sending the hydraulic oil pressure to the rear brake calipers. The piston inside the rear brake caliper starts to move under the pressure of the fluid, pushing the brake pads against the brake drum (or brake disc) to achieve braking effect .
The working principle of the rear brake caliper is as follows: When the driver steps on the brake pedal, the piston in the master cylinder is pushed, and the hydraulic oil is transmitted to the rear brake caliper through the oil pipe. The piston in the rear brake caliper is pushed by the hydraulic oil, which pushes the brake pads to rub against the brake drum (or brake disc), generating braking force that slows down the vehicle until it stops .
The fault manifestations of the rear brake caliper include decreased braking performance, sluggish braking, abnormal braking noise, overheating of the brakes, and brake deviation, etc. These faults affect driving experience and safety, especially at high speeds or in emergencies .
Therefore, it is very important to regularly inspect and maintain the condition of the rear brake calipers to ensure their normal operation and guarantee driving safety.
The reasons and solutions for THE rear brake calipers of AUTOMOBILE mainly include the following:
Youdaoplaceholder0 Change the brake fluid : Failure to change the brake fluid for a long time can cause impurities to accumulate in the brake fluid, affecting the return of the slave pump. The solution is to replace the brake fluid with a new one, ensuring it is clean and free of impurities .
Youdaoplaceholder0 Cleaning pistons and piston cylinders : If pistons and piston cylinders are stuck due to rust or impurities, clean them, sand the relevant parts and apply grease to ensure they move smoothly .
Youdaoplaceholder0 Replace the rubber sleeve : Aging or damage of the rubber sleeve will cause the brake fluid to drain faster, the parts to rust and affect the return of the slave pump. The solution is to replace the rubber sleeve with a reliable protective barrier .
Youdaoplaceholder0 Replace the brake pads : If the brake pads are not precise enough or too thick, they will prevent the piston from returning to its original position. The solution is to replace the brake pads with qualified precision and appropriate thickness .
Youdaoplaceholder0 Check and repair the guide sliding pin : Rust or damage to the guide sliding pin can cause a sliding failure of the sub-pump and affect its return. The solution is to sand, clean and grease it, or replace it with a new sliding pin .
Youdaoplaceholder0 Check and repair parts inside the sub-pump : If small parts inside the sub-pump are damaged, it can also cause the sub-pump not to return to its original position. The solution is to replace the brake calipers or caliper assembly with new ones .
Youdaoplaceholder0 Check the brake tubing and brake pads : Leaking brake tubing or severely worn brake pads can also cause the slave pump to fail to return to its original position. The solution is to check and replace the leaking tubing, replace the severely worn brake pads .
