Hydraulic Brake System Troubleshooting

It is possible that the connection from the brake pedal to the master cylinder is loose. The brake fluid reservoir is short of fluid. Broken brake line leaking oil. Brake master cylinder cup rupture, etc.

　　

If there is no sense of connection between the brake pedal and the brake master cylinder, it means that the two are loose, and it should be checked and repaired as soon as possible. When stepping on the pedal to brake, if it feels very light and there is a slight sense of resistance, it is time to check whether the brake fluid in the master cylinder chamber is sufficient. If there is a lack of fluid, add brake fluid to the designated position. When stepping on the pedal, if there is no sense of resistance, you should check whether the hoses and metal pipes of the brake master cylinder and brake wheel cylinder are broken and leaking oil. Step on the brake pedal, although there will be resistance, but the pedal position has obvious sinking, you should check whether there is brake fluid leakage on the push rod dust cover of the brake master cylinder, if there is leakage, it means that the master cylinder The cup is broken. If there is a large amount of brake fluid on the edge of the wheel brake drum, check whether the brake wheel cylinder cup is overturned and worn.
