What is a rear-wheel pump
Youdaoplaceholder0 The rear wheel pump plays a crucial role in the automotive braking system. It is mainly divided into two types: drum brake calipers and disc brake calipers.
Drum brake caliper
The drum brake caliper is an important component in the braking system. Its main function is to transmit pressure through the hydraulic system, pushing the brake pads to contact the brake drum, thereby generating friction to slow down or stop the vehicle. When the driver steps on the brake pedal, the master cylinder generates thrust, sending hydraulic oil pressure to the slave cylinder. The piston inside the slave cylinder starts to move under the hydraulic pressure, pushing the brake pads into contact with the brake drum, thus achieving braking effect .
Disc brake caliper
The disc brake caliper also transmits pressure through a hydraulic system, but its working principle is slightly different. The disc brake caliper pushes the brake pads to come into contact with the brake discs, generating friction for braking. When the brake pedal is depressed, the hydraulic oil in the master cylinder is pressurized to the slave cylinder, and the piston in the slave cylinder is pushed by the hydraulic pressure to bring the brake pads into contact with the brake disc, thus achieving braking effect .
Steps and precautions for replacing the rear wheel pump
Youdaoplaceholder0 Tools : Appropriate tools such as a wrench, screwdriver, etc. are needed.
Youdaoplaceholder0 Venting : During the replacement process, pay attention to venting to ensure that all air in the braking system is completely expelled.
Youdaoplaceholder0 Check other parts : During disassembly and assembly, check other related parts for problems such as small parts like springs that are prone to getting lost.
Youdaoplaceholder0 Safe operation : Ensure that the vehicle is in a safe condition during operation to avoid accidents.
By understanding the type, working principle, replacement steps and precautions of the rear wheel pump, the braking system of the car can be better maintained to ensure driving safety.
The main function of the rear brake caliper is to push the brake pads, and through the friction between the brake pads and the brake drum, reduce the vehicle speed and stop . When the brake is applied, the master cylinder generates thrust that pushes the hydraulic oil to the slave cylinder. The piston inside the slave cylinder starts to move under the hydraulic pressure, pushing the brake pads into contact with the brake drum to achieve braking effect .
In addition, the rear wheel brake caliper is an indispensable component of the braking system, ensuring the safety of vehicle operation. If the brake caliper fails, it may cause poor braking performance and affect driving safety .
Youdaoplaceholder0 The main causes of rear wheel pump failure include :
Youdaoplaceholder0 Damaged oil pump diaphragm : Damaged oil pump diaphragm will cause a slight leakage of oil .
Youdaoplaceholder0 Problems with the clearance between the distributor piston and the distributor wall : Uneven clearance, abnormal wear due to foreign objects, or the sealing rubber bowl being cut by foreign objects, poor quality, etc., can all cause oil leakage .
Youdaoplaceholder0 Brake fluid quality issues : Using an inappropriate type of brake fluid or poor quality brake fluid may cause oil leakage .
Youdaoplaceholder0 Manufacturing and processing issues : Problems existing in the manufacturing process of the piston or sub-pump may also cause oil leakage .
Youdaoplaceholder0 Solutions for rear wheel pump faults include :
Youdaoplaceholder0 Replace oil pump diaphragm : If the oil pump diaphragm is damaged, a new one needs to be replaced.
Youdaoplaceholder0 Adjust the clearance : Clear foreign objects between the distributor piston and the distributor wall to ensure uniform clearance, and replace the sealing rubber bowl if necessary.
Youdaoplaceholder0 Choose the appropriate brake fluid : Select the appropriate brake fluid type according to the vehicle manual and avoid using brake fluid from different manufacturers .
Youdaoplaceholder0 Repair or replace the distributor : If there is a problem with the distributor itself, it may be necessary to repair or replace the distributor .
Youdaoplaceholder0 Precautions and daily maintenance recommendations :
Youdaoplaceholder0 Check the brake fluid regularly : Ensure that the quality and type of the brake fluid meet the vehicle requirements.
Youdaoplaceholder0 Keep the brake system clean : Regularly remove foreign objects between the slave piston and the slave wall to prevent wear and leakage of oil.
Youdaoplaceholder0 Avoid prolonged braking : Prolonged braking causes severe wear and tear of the brake pads, affecting braking performance.
Youdaoplaceholder0 Regular maintenance : Regular inspection and maintenance are carried out in accordance with the vehicle maintenance manual, and problems are identified and resolved promptly.
