There is no set rule on how often to replace a car's rear break pads. Instead of using mileage or time as indicators, car owners must look out for unusual noises, grinding or vibrations as well as sub-par performance, and seek maintenance when needed.
The need to replace rear brake pads depends on how and where an individual drives. Generally, driving in an urban area involves more frequent and abrupt stops than driving on highways or in the countryside. Thus, car owners who mostly drive in the city must check their brake pads more frequently and usually must replace their break pads sooner. Some vehicles have sensors that alert car owners when the brake pads need replacement. Other indicators for brake pad replacement include longer stopping distances and pulsations felt through the brake pedal.
