What causes the rear wheels of Wuling Zhiguang to lock up after releasing the handbrake?
1 Answers
The reasons for the rear wheels of Wuling Zhiguang locking up after releasing the handbrake are as follows: 1. Lack of maintenance: Insufficient care for the braking system, excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid or mixing different types of brake fluid causing vapor lock when heated, leakage in the brake master cylinder or wheel cylinder, or air leakage in the air reservoir or pipeline connections. 2. Improper operation: Mechanical failure due to improper operation, such as prolonged downhill driving causing the brake pads to overheat, carbonization of the brake drum, and complete loss of braking function. 3. Severe overload: Due to severe overload, the vehicle's inertia increases under the effect of gravitational acceleration, directly leading to brake failure.
