Brakes are practically the most important safety device in your car. If you’ve ever partially lost your brakes in the past, you’ll agree that it’s not something you want to experience again. Wear and tear tests on your brakes twice a year will protect you and your passengers. It will also help you save money by catching any damage before it is too expensive.
Components of the brake system that may fail
The main cylinder, the heart of the vehicle’s braking system, retains brake fluid when it is not delivered to the brakes through the brake lines. If the brake fluid leaks due to wear on the main cylinder or the brake lines are clogged or damaged, the fluid cannot be delivered and the brake pads will be damaged.
The brake fluid itself absorbs moisture that causes rust and other debris, so it can become dirty or contaminated, or decompose due to overheating. Clean brake fluid is either slightly yellow or white, whereas dirty brake fluid may be brown or black. Old and dirty brake fluid can cause internal damage to the ABS brake systems.
The brake line is connected to the master cylinder via a combination valve that combines a metering and proportional valve. It adjusts the pressure on the front and rear wheels to ensure that both sets of brakes are applied at the same time. Failure of the combination valve may cause the wheels to lock up.
Brake pads and shoes may be made of ceramic, metal or organic materials while metal is used for the disk rotors and drums against which they press back. Since the pads and shoes cause friction to stop the engine, they wear down slowly over time and can wear away completely,
