When you press the brake pedal, the brake pads and drum brake shoes press against the brake rotors and drums creating friction, which slows the vehicle. The brake pads and shoes are comprised of a metal backing plate and a friction material. The friction material rubs against the brake rotor and drum and with time wears down. Worn brake pads can SEVERELY degrade stopping performance and potentially lead to an accident. When your brake pads or shoes are worn you can sometimes experience what is called a “long” brake pedal.
This means that you have to press further on the pedal to get the brakes to engage. You can also experience a “mushy” sensation. In extreme cases the pad or shoe may be SO low that the metal wear indicator may contact the brake rotor or drum, further diminishing stopping performance.
Genuine Mitsubishi brake pads and shoes are designed for long life, powerful stopping performance, quiet operation, and minimal brake dust. Some non-genuine pads may provide one or two of these attributes, but compromise others. For instance, a non-genuine brake pad may provide strong stopping power, but at the expense of quiet, dust-free operation. A car with noisy brakes can be a significant annoyance, while a pad that emits large amounts of dust can cover your wheels with black powder that is difficult to remove.
Signs of Wear
Any grinding, squeaking or squealing noises while braking may indicate worn brake pads or shoes. Once the brake pads wear down to a thickness of less than 2mm (0.080 inch) the pad will need replacement. The wear limit for brake shoes is 1.0 (0.040 inch)
If you ever hear unusual noises while braking,have your vehicle inspected by a qualified technician like those at your Mitsubishi dealer.
WARNING: Driving with worn brake pads will make it harder to stop and can cause an accident.
Because everyone’s driving habits differ, there is no standard life expectancy for brake pads. It is important to have your vehicle’s brake pads inspected regularly. Changing brake pads before they wear completely will prevent expensive repairs to braking system components and ensure your vehicle is capable of stopping in an emergency.
