How to Solve ABS Automatic Lock-Up?
1 Answers
Solutions for ABS automatic lock-up: 1. ABS lock-up may be caused by factors such as a stuck brake master cylinder cup that fails to return, insufficient rigidity of the brake disc, improper fit of the brake pads, or poor coordination of internal components in the rear brake. 2. ABS (Anti-lock Braking System) is used in vehicles to prevent loss of control and generally reduces braking distance to enhance vehicle safety. Installing an ABS system in a vehicle helps avoid directional loss and wheel skidding during emergency braking, preventing the wheels from locking up. This ensures that the tires do not rub against the ground at a single point, thereby increasing friction and achieving a braking efficiency of over 90%. Additionally, it reduces brake wear and extends the service life of brake drums, discs, and tires by up to twice as long. 3. Based on speed signals from each wheel speed sensor, the ABS quickly determines if a wheel is locking up. It then closes the normally open input solenoid valve for the locking wheel to maintain braking force. If the wheel continues to lock, the normally closed output solenoid valve is opened, allowing the brake pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir. This prevents the wheel from completely locking up due to excessive braking force.
