1. We must pay attention to the degree of wear of the brake band of the electric hydraulic brake or the friction material of the brake pad;
2.pay attention to the brake friction surface of the brake wheel should not have defects that hinder the braking performance or be contaminated with oil;
3. The control parts (such as pedals, joysticks, etc.) of the electric hydraulic brake to be controlled should have anti-skid performance;
4. The actual contact area between the brake band or brake shoe and the brake wheel should not be less than 70% of the theoretical contact area; the processing of the worm of the brake accessory
