Common Equipment Failures And Solutions Of Semi Trailers

1. The brake system is not good, the brake system is slow

Excessive clearance between brake pedal friction pad and brake system drum: adjust the clearance

Excessive damage of brake pedal friction pad: remove and replace the brake pedal friction pad

Air leakage in the air braking system reduces the working pressure: check the components with air leakage, repair or replace the parts

Poor operation of emergency relay valve: disassembly and replacement

2. The brake system cannot be eliminated or the brake system is very slow

The emergency relay valve has emergency braking function: increase the working pressure of the air braking system to the specified value

Brake system return spring is broken: replace the spring

Pipe blockage: Inspection and removal

Bending of air chamber push rod of brake system: repair or replace parts

Incorrect stroke of air chamber push rod of brake system: readjust
