What are the common faults of parking brakes?
1 Answers
Parking brake faults are as follows: 1. Parking brake failure: The main causes of failure are excessive clearance between the friction plate and brake drum, oil contamination on the friction plate or brake drum, or severe wear of the friction plate. Immediate repair is required. 2. Abnormal noise: Manually swing the parking brake to check for loose fixing screws, deformed operating lever, loose fixed pins, or damaged operating lever spring. Timely repair and adjustment are necessary. 3. Parking brake lever cannot be fixed: At the unfixed braking position, inspect the lever head. Grip and release the lever handle, perform up and down movement tests to check if the lever is bent, stuck, or if the spring is broken.
