Slow braking accompanied by a thumping sound may indicate unbedded brake pads or a faulty brake caliper. Below are detailed explanations of the causes: Unbedded Brake Pads: When braking produces a sharp, screeching noise, many car owners assume it must be a vehicle quality issue. In reality, this is not the case. New brake pads and rotors require a bedding-in period. If braking happens to grind against a hard spot on the pad (due to material composition), this abnormal noise occurs, which is entirely normal. Faulty Brake Caliper: A dull thudding sound during braking often points to a malfunctioning brake caliper. Issues such as worn guide pins or detached spring clips can prevent the caliper from operating correctly.
