What Are the Causes of Brake Dragging?
1 Answers
Here are the main causes of brake dragging: 1. No free travel in the brake pedal. 2. Broken or missing brake pedal return spring. 3. Internal failure of the master cylinder. 4. Internal failure of the relay valve. 5. Poor exhaust in the brake system. 6. Rusting or sticking of the brake wheel cylinder. Here are the main solutions for brake dragging: 1. Most brake dragging faults are caused by rusted brake transmission components. These parts can be disassembled, derusted, and lubricated, which generally resolves the brake dragging issue. 2. For air brake systems, the more common faults occur in the air pressure control system, such as air leaks in the master cylinder, hand brake valve, or relay valve. These components should be replaced as soon as possible.
