What is the purpose of brake repair?

The core purpose of brake maintenance is to ensure that the braking system is always in optimal working condition, so as to guarantee driving safety, handling stability and the service life of components. The braking system converts kinetic energy into thermal energy through friction to achieve deceleration or stopping, and its key functions include forced deceleration (e.g., in response to sudden road conditions), stable parking (to prevent vehicle rollaway), and control of downhill speed (to avoid thermal fade). Wear or failure of these components can lead to extended braking distance, abnormal pedal feel (either too soft or too hard), or uneven braking force. For example, brake pads must be replaced when their thickness is less than 3mm; otherwise, the metal backing plate directly contacting the brake disc will cause sharp noises and damage the brake disc. The cost of a single replacement ranges from approximately 200 to 800 ringgit, depending on the vehicle model. In addition, regular maintenance can prevent the decrease in boiling point caused by brake fluid absorbing moisture (which may lead to vapor lock). It is best to replace DOT4 standard brake fluid every 2 years or 40,000 kilometres. Sudden braking accelerates the wear of brake pads (typically, front brake pads last 30,000 to 50,000 kilometres, while rear ones last 50,000 to 70,000 kilometres), whereas smooth and anticipatory driving can extend component service life by over 20%. For models equipped with electronic parking brakes, the motor module also needs to be calibrated regularly to ensure parking reliability.
