How to Deal with Rear Wheel Locking on Wuling Hongguang?
2 Answers
Rear wheel locking can be resolved by releasing the handbrake, using a spare tire, or simply kicking the sidewall of the tire a few times. To prevent locking issues, an anti-lock braking system (ABS) can be installed. Below is an introduction to the anti-lock braking system: 1. Definition: The anti-lock braking system, abbreviated as ABS, functions by automatically controlling the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a state of rolling and sliding (with a slip ratio of about 20%), thereby ensuring maximum traction between the wheels and the road. 2. Classification: ABS can be categorized by manufacturer and by the number of control channels.
I've repaired quite a few minivans. For the Wuling Hongguang's rear wheel locking up, it's mostly due to a stuck handbrake cable or a rusted/seized brake caliper. First, try releasing and pulling the handbrake back and forth about ten times—sometimes the jammed cable can reset. If that doesn't work, lightly tap the rear wheel's brake drum with a hammer to loosen the rusted brake shoes. Never force it open if it remains stuck, as this will wear out the tire and require replacing the entire brake system. If possible, remove the tire to inspect the caliper piston; replace it if severely rusted, and promptly change the handbrake cable if it's stuck. Remember not to park with the handbrake engaged immediately after washing the car, as water entering the caliper can cause rust. Avoid using the handbrake for parking longer than three days.
