What to Do When Brakes Lock Up After Rain?
1 Answers
One method is to force start the engine and step hard on the accelerator; as long as the rear wheels move, the issue should resolve. Another approach is to remove the tire and lightly tap the brake drum with a hammer or similar tool a couple of times to loosen the contact surface between the brake drum and the brake pads. Below are the classifications related to brake lock-up: 1. Brake lock-up caused by the brake caliper not retracting: Simply put, even when not pressing the brake pedal, you 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, leading to 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. 2. Static wheel lock-up after parking: The vehicle is parked statically and locks up after sitting overnight. This phenomenon often occurs in vehicles with rear drum brakes. The friction pads are semi-metallic based, and the brake drums are made of cast iron. When the parking brake is engaged, the brake pads and brake drums are tightly pressed together. Exposure to water causes metal oxidation and rust, leading to adhesion. The solution is to spray rust remover or sand with sandpaper.
