What's the reason when the handbrake is released but the rear wheels don't move?
2 Answers
The reasons why the rear wheels don't move after releasing the handbrake include rusted brake pads and locked rear drum brakes. Below are detailed explanations for this situation: Rusted brake pads: Sometimes it's caused by rust on the brake pads or brake discs. You can try shifting into drive to move forward slightly, then shift into reverse to move backward, repeating this cycle several times to resolve the issue. Locked rear drum brakes: If the rear drum brakes are internally locked and remain engaged after releasing the handbrake, first remove the rear wheels and then open the drum covers. Check if rust is causing the locking. Prepare some WD-40 to spray inside, and when testing the brakes afterward, press the brake pedal several times until everything functions normally.
I often encounter similar issues working at the auto repair shop. When the car's handbrake is released but the rear wheels don't move, it's mostly caused by either rusted and stuck handbrake cables or adhesion between the rear brake pads and discs. This happens especially after humid weather when moisture causes metal components to rust and seize. I recommend trying to put the car in neutral and gently pushing it or driving a short distance to see if it can release the adhesion. If unsuccessful, forcing the car to move may damage the cables or other components, so it should be sent for repair immediately. Additionally, try to use the handbrake less when parking, especially on slopes—use gear parking instead to reduce wear. Regularly applying anti-rust lubricant to the cables can prevent this problem, particularly in older car models which are more prone to such issues.
