What Causes a Car Not to Move When the Handbrake Is Released?
4 Answers
If the handbrake is released but the car still cannot move, it may be due to a malfunction or internal jamming of the handbrake. Below is more information about the automotive braking system: 1. Introduction: The braking system is a series of specialized devices designed to forcibly reduce the speed of a vehicle. It mainly consists of four parts: the energy supply device, control device, transmission device, and brake. 2. Function: The primary functions of the braking system are to slow down or even stop a moving car, maintain a stable speed for a car going downhill, keep a parked car stationary, ensure the vehicle can decelerate or stop as required by the driver, and guarantee the safety of both the car and the driver.
Once on a cold and damp winter night, I parked my car and left the handbrake on. The next morning when I released the handbrake to leave, the car wouldn't budge. I initially thought the transmission was broken, but a friend pointed out that it might be due to the handbrake cable being rusted and stuck. The handbrake system is usually located at the rear wheels. If the cable doesn't fully release when the handbrake is lowered, the brake pads will continue to clamp the wheel hub, causing the wheels to lock. Similar situations can also occur due to rusted or deformed brake drums or improper handbrake adjustment. Cars that are left unused for long periods are more prone to this issue. In such cases, try gently rocking the car back and forth or lightly tapping the inner side of the wheel hub with a hammer to see if it loosens. If all else fails, call a tow truck to take the car to a repair shop for inspection and maintenance to prevent damage to other components.
I'm the type who loves tinkering with my car. Last time, after releasing the handbrake, the car wouldn't move, so I immediately got out to inspect the rear wheel brake calipers. It turned out that the handbrake cable was clogged with sludge, preventing the spring from resetting. In such cases, it's best to use a pry bar to loosen the brake or check if the brake cable is aged or broken. If replacing the new cable doesn't solve the issue, you may need to adjust the handbrake tension nut or clean the carbon buildup in the wheel cylinder. Regularly lubricating the cable to prevent sticking is essential, especially during rainy seasons. DIY can save money, but for more complex issues, it's advisable to seek professional help.
It's quite common for the car not to move after releasing the handbrake, likely due to a mechanical issue like rusted rear brake pads sticking or a twisted cable. I've experienced this before - gently starting the engine and trying to move forward and backward a few times might release it. Don't force it to avoid cable breakage. If that doesn't work, consult the repair manual or take it directly to a mechanic - safety first. For regular parking, avoid keeping the handbrake tightly engaged for long periods or use gear positioning to reduce load.
