What's the reason when the handbrake is released but the rear wheels don't move?

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.

As an ordinary car owner, I've encountered this situation before. That time after parking in the rain, I forgot to release the handbrake. The next day when I pulled the handbrake down, the rear wheels still wouldn't move. Later I learned it might be because the rear brake discs and pads were frozen or stuck together. I slowly reversed for a short distance until I heard a "pop" sound when they released. Now I've developed good habits: checking if the handbrake is fully released when parking, and leaving the car in gear when not using it for long periods. If you encounter this issue, don't worry - try driving a short distance to see if it releases naturally. If not, go for repairs immediately to avoid rear wheel lock-up while driving which could cause loss of control. Pay extra attention during significant weather changes, and regular car washes to remove dirt from the rear wheel area also help prevent this.

I know a bit about this issue. It could be that the handbrake mechanism is stuck or the rear wheel bearings have failed. Simply put, the handbrake is released but the rear wheels aren't turning, which could be due to aging cables, brake pads not retracting, or rusted components. If you've confirmed the handbrake is indeed released, try gently driving to see if it can break the adhesion; if not, you'll need a professional mechanic to inspect the system with tools. This can happen to both new and old cars—don't ignore it, as continued driving may worsen the braking system. Address it promptly to avoid complete rear wheel lockup affecting driving safety. Pay attention to parking conditions to minimize exposure to moisture.
