What is a brake? The brake is the brake or brake we talk about everyday. It is a Machine element that stops or decelerates moving parts in machinery.
So what are the types of brakes? There are two types of brakes: hydraulic brakes and block brakes.
The function of the brake is obvious and crucial, so what happens when the brake malfunctions?
Below, we will analyze the common troubleshooting of hydraulic brakes.
Hydraulic braking equipment transfers braking force by converting pedal force into hydraulic energy. Its transmission organization is simple, but the braking torque generated by the brake is linearly related to pedal force. If the adhesion between the tire and the road surface is met, the braking force experienced by the car is linearly related to pedal force. This function is called brake pedal feeling (commonly known as foot feeling), so the driver can directly feel whether various working conditions of the automobile brake equipment are normal, so as to quickly diagnose. Common faults in hydraulic braking systems include: ineffective braking, such as brake bite.
1、 Brake failure
1. Appearance: When the car is moving, quickly press the brake pedal to the bottom, and the car cannot immediately slow down or park. Its braking
The deceleration is small and the braking interval is too long.
2. Reason:
(1) Excessive pedal free travel.
(2) Lack of brake fluid in the brake master cylinder, or blockage of the compensation hole, aging, swelling, deformation, or overturning of the master cylinder cup and ring.
(3) The brake master cylinder piston and cylinder body are excessively worn and loose, resulting in oil leakage, poor sealing of the return valve, and broken tension spring of the outlet valve.
(4) The brake wheel cylinder cup is aged, swollen, and the piston is stuck, resulting in excessive wear and loose oil leakage between the wheel cylinder piston and the cylinder body.
(5) The brake shoes are severely worn, and the brake clearance is too large or reversed.
(6) The brake drum is out of round, grooved or worn too thin, the brake shoe surface has oil, burns and hardens, and rivets are exposed.
(7) When air enters the hydraulic braking system or the temperature of the braking system is too high, the brake fluid in the pipeline vaporizes, forming an air lock.
(8) The oil pipe is concave, the joint is loose and leaking, and the brake hose is aged, cracked, or blocked.
