A Brief Discussion on the Failure Forms of Brakes by Brake Manufacturers
The main manifestations of braking failures are: brake failure and lockup.
1. Brake failure
The first thing that came to mind was a shortage of oil in the hydraulic pipeline. Check if there are any leaks in the brake wheel oil pump and oil pipe.
2. Brake locking
The brake cannot be opened. After dismantling, it was found that the brake was burnt out.
