Why does the Corolla make a clunking sound when braking?
3 Answers
The reasons why the Corolla makes a clunking sound when braking are: 1. Excessive wear of the brake disc and brake pads: Both the brake disc and brake pads are high-wear items. Friction occurs between these two components during braking, leading to natural wear over time. When the wear becomes excessive, abnormal noises will naturally occur. Regular inspection and replacement are necessary. 2. Improper installation of the brake pads: When installing brake pads, car owners should have the work done at a professional auto repair shop. Taking the Corolla 2021 TNGA 1.5L Manual Pioneer Edition as an example: its engine has a maximum torque of 148 Nm, a maximum power of 89 kW, is equipped with a 6-speed manual transmission, has a fuel tank capacity of 50L, uses a MacPherson independent suspension for the front suspension, and an E-type multi-link independent suspension for the rear suspension.
I noticed that after driving my Corolla for a while, there's a clicking sound when I step on the brakes, similar to the sound of lightly clicking a mouse. I asked a few friends who also drive Corollas, and they said it might be due to loose brake pads or debris stuck on the brake rotors, especially if the rotors rust after rainy days. The braking system in a family sedan like the Corolla is designed to be simple and reliable, but it's prone to dust accumulation, which can affect performance. It's recommended to take some time to visit a repair shop to check the brake pads and rotors. If they're worn out, they should be replaced promptly. Parking in dry places can help reduce rust accumulation, extend the life of the brakes, and ensure driving safety. This is advice from experience—addressing issues early saves money in the long run.
With my extensive driving experience and having driven many cars, the Corolla's brake clunking noise is usually caused by loosely installed brake pads or uneven rotor surfaces, resulting in movement sounds. Sometimes, the ABS is triggered only during emergency braking, but the sound you described doesn't seem to fit this scenario. It's advisable not to attempt DIY fixes. First, check the brake rotor surface for any scratches or signs of wear. The Corolla's braking system is durable, but regular maintenance is key to preventing issues before they arise. Have a professional mechanic inspect it with proper tools for peace of mind while driving. Brake noises are more common in humid weather. Try cleaning the brake components to see if there's any improvement. Don't ignore minor issues, as they may indicate larger faults, such as loose suspension, which can indirectly affect braking.
