How to repair the car brake failure?

Causes and treatment of brake failure;

1. First check whether the brake fluid level is normal and whether the air intake of the brake system is leaked. If yes, add the brake oil to the specified position to exhaust, and the exhaust fault will be eliminated. Check whether the brake master cylinder and four-wheel cylinder work normally and whether there is any leakage. If there is leakage, replace the master cylinder or cylinder.

2. If the first inspection is normal, remove it to check whether the tire brake pad exceeds the wear limit, and if so, replace it with a new one.

3. Check whether the brake cylinder is rusted and replace it with a new pump.
