Why does the handbrake area get very hot?
3 Answers
Handbrake heating occurs because the exhaust pipe passes beneath the handbrake area, transferring heat upward during driving. Not only does the handbrake get hot, but the center console may also become warm, which is a normal phenomenon. Below is additional information: 1. Handbrake Introduction: The professional term for the handbrake is auxiliary brake. Unlike the main braking system, it uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce effectiveness and increase the handbrake's travel distance. 2. Precautions: When stuck in traffic on a slope, never forget to engage the handbrake. If you usually forget to pull the handbrake when parking and the vehicle starts to roll backward, stepping firmly on the foot brake may prevent significant danger. However, if you encounter traffic on a slope and forget to engage the handbrake, it can be extremely hazardous.
Recently, every time I get out of the car after driving, I feel the area near the handbrake is extremely hot. This is most likely because the handbrake was pulled too tight or not fully released, causing the brakes to keep generating slight friction heat after parking. That heat can transfer through the floorboard into the car interior, especially in summer when the car is well-sealed and heat can't dissipate easily. Normally, the car should cool down within a few minutes after parking. If it remains excessively hot, it might indicate worn brake pads or an electrical issue, and you should get it checked at a garage immediately. Otherwise, prolonged issues like this can increase fuel consumption and the risk of brake failure. Safety first—I always make sure not to pull the handbrake too tightly when parking, leaving a bit of slack.
As a frequent driver, I understand the reasons behind the handbrake area getting hot. The main cause could be dragging brakes, meaning the handbrake wasn't fully released when parked, causing the brake pads to continue rubbing and generating heat while driving. The accumulated heat in the chassis area then rises. For electronic parking brakes, it's more complex - motor or sensor malfunctions can also cause overheating. This isn't just uncomfortable; it poses hidden risks: high temperatures may ignite interior materials or accelerate component aging. Developing the habit of releasing the handbrake after parking and regularly inspecting the braking system can prevent most issues.
