For brake failure, we may only appear in the braking force of brake or abnormal noise will be found. If you are traveling at high speed and other conditions, it is very dangerous! In fact, we usually use the Auto diagnostic tool you can determine the brake system problems, and these details are likely to be ignored for everyone.

brake failure

First, when the brakes shudder
This situation occurs mostly in old car, because the use of wear, brake disc surface roughness has a certain degree of misalignment. It is proposed that, as the case opt lathe sanding disc technology, or replace the brake pads.

Second, when the brake quickly stopped, the steering wheel will always to the side deflection
In fact, this situation is what we called "partial brake", the main reason for the failure is about the brake system Cylinder uneven forces on the brakes caused. And in the process of moving due to the rotation speed brakes, wheel cylinder uneven role in the fast friction difference is very small, we can hardly feel it. But when the vehicle stopped quickly when the difference is obvious, that the speed of the wheel stopped on one side of priority, the steering wheel will deflect. This may need to Launch X431 GDS and Launch X431 V Pro tools to detect.

brake failure

Third, driving need heat 10 minutes before the brake force
Is provided by the engine brake system pressure to promote calipers grip brakes, or push the brake drum friction brakes. So like the above conditions, may provide pressure transmission pipelines loss of pressure occurs, resulting in not timely provide braking force. This situation should be checked at the pretext of the vacuum booster hose and brake master cylinder engines have cracks or loose condition.

brake failure

Fourth, the brakes do not return
Step on the brake pedal, the pedal does not rise, no resistance, a phenomenon that the brakes do not return. Need Autel MaxiSys Mini MS905 and Autel MaxiSys MS908 tool to determine whether the brake fluid missing; whether the brake wheel cylinders, pipes and joints leak; whether the master cylinder, slave cylinder parts damaged.
