Why does the Volkswagen T-Roc make abnormal noises at low speeds?
1 Answers
Abnormal braking noises at low speeds are likely due to severely worn brake pads, where the warning shim emits sharp abnormal sounds to prompt replacement. Alternatively, excessive wear on the brake disc or brake drum, which becomes too thin, can also cause abnormal noises. Another possibility is that newly replaced brake pads may not fit properly with the brake disc or drum, resulting in point or line contact that generates abnormal noises. Additional information is as follows: 1. Brake lifespan: The replacement cycle for brake pads is not fixed and depends on the vehicle's driving conditions, the frequency and intensity of the driver's use of the brake pedal. Front brake pads wear out faster than rear ones, with a lifespan of approximately 30,000-50,000 kilometers for front brake pads and 100,000-150,000 kilometers for rear brake pads. 2. Specific causes: Faults in the caliper, brake disc, or brake pads can all produce such noises. If the noise is continuous, the first step is to check for dragging brakes, as poor caliper reset can cause prolonged friction between the disc and pad, leading to abnormal noises under certain conditions. If the noise occurs immediately after installing new pads, it may be due to a mismatch in size between the new pads and the friction block.
