Why does the car make a noise when starting after releasing the handbrake?
2 Answers
This situation is normal, as it occurs when the brake pads and brake discs stick together, causing the brake pads to snap back when starting. Here is some additional information: 1. The braking system is a crucial component of a car, directly affecting driving stability and safety. 2. The main components of the braking system include the vacuum booster pump, master cylinder, wheel cylinder, brake pads, and brake discs. 3. Both brake discs and brake pads are wear-and-tear parts that require regular replacement. As the car's mileage increases, the brake pads and brake discs will gradually wear out.
I've been driving for over a decade, and the noise when releasing the handbrake to start moving has always annoyed me. It's usually caused by adhesion between the brake pads and brake discs, especially on rainy days or during winter when humidity is high and rust forms on the discs, resulting in squeaking or creaking sounds when released. Another possibility is aging or rusting of the handbrake cables or springs, where accumulated rust and dust cause uneven friction. Ignoring it may lead to more frequent noises or even affect braking safety. I make it a habit to regularly check the thickness of the brake pads and, after parking in damp areas, warm up the car to dry the components and reduce adhesion issues. If the problem persists, it's best to have it checked at a shop to prevent minor issues from turning into accidents. This is actually a common issue with older vehicles, so there's no need to worry too much, but it shouldn't be neglected either—safe driving should always come first.
