Disc Brakes Disc brakes components1. Brake discs (or rotors)2. Calipers3. Brake pads 4. Brake lines5. Brake master cylinder6. Brake fluid reservoir7. Brake pedalA disc brake has a plate-like disc (also called a rotor) attached to the wheel. This disc is squeezed by the brake pads within a caliper, much the same way that you might squeeze a spinning plate between your thumb and fingers to slow it down. As the brake pads press against the brake disc, an enormous amount of heat is generated, therefore; they can warp, crack, or even become dis-aligned. They can even be damaged by worn out brake pads that scratch grooves into the surface. These conditions result in less contact surface for the brake pads leaving you with reduced braking power also known as 'brake fading'.When brakes fade:The pedal depresses farther (closer to the floor).The distances it takes to stop increase dramatically.The brakes emit a burning odor.In the most extreme cases, the pedal can depress all the way to the floor without any braking action occurring and the brakes can actually smoke or catch on fire. When brake fade happens, the only thing you can do is pull over and allow your brakes to cool and simply replacing the brake pads on a wheel with a bad rotor will not fix the problem, but our ASE Master Certified Technicians at Auto Repair Service can help you get it done right.
