The brake system is an important part for your vehicle, and the brake pads are the component that provides the friction to slow your vehicle. They are located in the brake calipers and function by pressing against the disc brake rotors with friction material to slow and stop the wheels. As they are a contact wear item, the brake pads will eventually wear out over time and need to be replaced.
The most common symptom of bad or failing brake pads are noisy brakes. Brake pads can accumulate dust as they wear, which if allowed to build excessively, may cause vibration and squealing when the pedal is applied or let off. Squealing brake pads can also be caused by excessively worn pads that have worn down to the point where the wear sensor has come into contact with the rotor. Severely worn brake pads, ones that have worn all the way to the brake pad backing plate, will produce a scraping sound as a result of the metal-on-metal contact between the brake pad backing plate and the rotor. Depending on the extent of the wear, the scraping may be heard when the vehicle is in motion or when you apply the brakes.
Another symptom of bad or failing brake pads is a pulsating brake pedal. Severely or abnormally worn pads can cause the pedal to pulsate when the brakes are applied. A pulsating pedal may also be indicative of a potential problem with the rotor as well, as the pulsation felt in the pedal is a result of the contact between the rotor and brake pad.
Bad or failing brake pads can also cause poor brake response. If the brake pads have been excessively overheated or severely worn, their capacity to slow the vehicle may be hindered as a result. Make sure to contact us so we can inspect the vehicle for you.
