Fault Diagnosis of automotive brake systems overhaul

1, the braking effect car diagnostic tool is adverse automobiles with braking, the braking deceleration is little, the braking distance is extended. Is generally because of: 1. Slave cylinder or master cylinder oil leakage can not assure sufficient oil pressure; brake failure; three. Brake lines penetrate the air. The factors for poor braking performance hydraulic brake program could typically be based on the brake pedal stroke, pedal when the brake pedal feeling of soft and hard, the following step to figure out the stability from the brake pedal.
Maintain brake pedal height slow decline, ruptured brake line somewhere, poorly sealed joints, master cylinder or wheel cylinder piston seal undesirable, terrible oil return valve and valve. Be the very first step around the brake pedal and observe regardless of whether the brake fluid leakage location. In the event the external standard, you ought to check the wheel cylinder or master cylinder failure. Consecutive kicks brake pedal height is slightly elevated, plus a bomb attractive, infiltrated the air inside the brake lines.

2, the brake suddenly failed
The auto Launch X431 GX3 is moving, kick or kicks within a row brake, brake pedal have been riding inside the finish, brake all of a sudden failed. Causes: 1. Brake Master Cylinder oil spill really serious; two. Brake master cylinder or wheel cylinder piston seal is broken, or also significantly air in the brake oil line. If this takes place, the driver must be rapid succession feet on the brakes. The occurrence of your failure on the brake failure, must be right away stopped and checked. First, observe no matter if the loss of brake fluid in the brake fluid tank, then observe the brake master cylinders, wheel cylinders, tubing leaks brake fluid.

3, the brake deviation
Braking, the path of deviation, specially automobiles not equipped with ABS anti-lock braking devices, directional handle can not, the explanation for uneven brake put on, master cylinder, a piston oil seal expansion, a wheel cylinder as a consequence of the oil spill.

4, Brake jitter
Shimmy, steering wheel play the hand brake. Swing differential overrun brake disc deformation from the brake caliper, brake pads ground into a cone. This occurs ought to be into the factory for repair.

5, the brake squeaky
Generally Launch X431 GX3 brake discs, brake pads or brake drum, due to the uneven shoe put on.

6, brake back
The brake pedal was each higher and really hard, there's no totally free travel, cars challenging to start or driving work. Failure phenomenon: step on the brake pedal, the pedal does not rise devoid of resistance. Have to have to figure out regardless of whether the brake fluid missing; brake wheel cylinders, piping and joints for leakage; master cylinder, wheel cylinder parts for damage.
