How to Solve the Slow Return of the Spring Brake?
1 Answers
Solutions for the slow return of the spring brake are as follows: 1. The issue of slow brake return is somewhat related to the performance of the brake master cylinder. It is recommended to check whether the piston of the brake slave cylinder is stuck due to dirt. Another possible cause is that the guide pipe fixing the brake slave cylinder is stuck, preventing the brake slave cylinder from returning. 2. Check the assembly condition of the return spring on the brake pedal to ensure it is normal and not detached. If abnormal, replace the corresponding parts and reassemble. Additional Information: 1. The spring brake method is mostly used in the handbrake systems of medium and large-sized vehicles. The handbrake system of such vehicles is usually in a constant braking state with a strong spring. When the vehicle needs to move, the driver releasing the handbrake is an inflation action. A certain air pressure must be reached to push open the spring, i.e., to release the handbrake, before the vehicle can move. 2. Under normal circumstances, the reasons for a truck's brake not returning include: brake locking, brake not returning or returning slowly, bearing damage, improper tightness of the axle head, abnormal tire pressure, or frequent use of brakes under excessive load conditions, all of which can cause high temperatures in the tires and axle head.
