Your automobile’s braking system may be one of the most important safety systems in your vehicle. The braking system functions by applying friction to the wheels. This is accomplished with hydraulics. When you apply pressure to the brake pedal, the master cylinder forces the brake fluid via the brake lines into the wheel cylinders and calipers. This activates brake shoes against the drums, the brake pads, which rub against the rotor, and this slows your automobile down. Checking the parts of your brakes, such as the rotors, brake pads and brake fluid regularly and servicing them annually or every 24,000km will ensure that they wear and function properly maximizing the performance of your brakes and your safety! Servicing is much like a dental cleaning. Parts are disassembled, inspected for wear, cleaned and lubricated on reassembly.
