What are the common brake system problems for refrigerated trucks?

1, the phenomenon of failure: step on the refrigerated car brake pedal, pedal does not rise, no resistance;

Determine the reason: check whether the brake fluid is missing; whether there is oil leakage in the brake cylinder, pipeline and joints; whether the main pump, pump parts are damaged;

2, the phenomenon of failure: the brake pedal stepped in the end, the brake effect is not good; continuous braking, the effect did not improve, and the pedal gradually increased;

Reason for judgment: The brake system is mixed with gas;

3, the phenomenon of failure: continuous brake pedal, pedal back to increase, the brake effect has improved;

Reason for judgment: The gap between the friction plate and the brake drum is too large;

4, the phenomenon of failure: continuous brakes, pedal position, and a sense of subsidence;

Reason for judgment: oil leakage;

5, the phenomenon of failure: the pedal position is very low; then step, the location can not be increased, feeling hard;

To determine the reason: the total pump is blocked;

6, the phenomenon of failure: pedal height is normal, not soft not sink, but the brake effect is not good;

To determine the reason: friction plate and brake drum clearance is too large or oily;

7, failure phenomenon: brake deviation;

To determine the reason: if the refrigerated truck skews to the left, it will not work properly for the right wheel, and vice versa;

8, failure phenomenon: refrigerated truck driving mileage, brake drum (disc) heating;

To determine the reason: check the master cylinder, brake cylinder or pipeline;

9, the phenomenon of failure: brake pedal free travel too small;

Judgment reason: need to adjust;

10. Failure phenomenon: The brake fluid picks up slowly;

Determine the reason: Loosen the bleeder screw and observe the brake shoe return. If the brake shoe returns, the tubing should be dredged; if the brake shoe does not return, the brake cylinder should be disassembled.
