It is possible for several problems to manifest themselves if worn-out brake pads are not replaced. It is possible for the metal backing of the brake pads to come into contact with the braking rotor when the pads wear down, which may cause significant damage to both components. This may lead to a decrease in braking performance, increased stopping distances, and even the possibility of the brakes failing. Ignoring worn brake pads may cause further damage to other components of the braking system, which can result in expensive repairs and a reduction in the level of road safety.
