What to Do When the Handbrake of a Van Locks Up?

[VanAliyah]

If the wheel is statically locked, the best solutions are spraying rust remover or sanding with sandpaper. Here are the detailed explanations: 1. Lock-up after static parking: The vehicle is statically parked and locks up after sitting overnight. This phenomenon often occurs in vehicles with drum brakes on the rear wheels. The friction pads are semi-metallic-based brake pads, and the brake drum is made of cast iron. In the handbrake engaged state, the brake pads and drum are tightly pressed together, leading to adhesion due to oxidation and rust when exposed to moisture. 2. Lock-up caused by the brake caliper not retracting: Simply put, even without pressing the brake pedal, you can still feel significant resistance from the vehicle. In severe cases, abnormal noises may occur, or the wheel may even lock up. If the brake fluid hasn't been changed for a long time, causing internal rust in the brake caliper, it can be repaired by sanding with sandpaper and applying grease. If the caliper itself is faulty, it may need to be replaced directly.
