The malfunction of the braking force distribution system may be caused by the battery running out of battery, and replacing the battery is sufficient; Or if the distribution valve is faulty, replace it. A malfunction in the brake force distribution system may cause brake failure; Abnormal noise during braking; The effective distance becomes longer or shorter; Brake bias or tail flick; Sometimes not during braking; Changes in braking stroke (such as lengthening or hardening); Shaking during braking.

The following is an introduction to the functions of EBD:
1. The function of EBD is to calculate the friction value of four tires due to different adhesion at high speed at the moment of vehicle braking, and then adjust the braking device so that it can be adjusted at high speed in motion according to the set procedure to match the braking force and friction (traction), so as to ensure the stability and safety of the vehicle;
2. When the wheels lock up during emergency braking, EBD has already balanced the effective ground grip of each wheel before ABS action, which can prevent tail shaking and lateral displacement and shorten the braking distance of the car;
3. EBD is actually an auxiliary function of ABS, which can improve and enhance the effectiveness of ABS. So in terms of safety indicators, the performance of cars has added "ABS+EBD".
