Brake Repair: Pads, Rotors, Lines, Cylinders

Brakes are the most important safety device on 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. Inspecting your brakes twice a year for wear and damage can protect you and your passengers. Additionally, it will also help save you money by catching any damage before it becomes too costly.

Brake System Components That Can Fail

The master cylinder, the heart of the vehicle’s braking system, holds the brake fluid when it is not being delivered to the brakes through the brake lines. If brake fluid leaks because the master cylinder is worn or brake lines are plugged or broken, the fluid cannot be delivered, and the brake pads will become ruined.

The brake fluid itself can become dirty or contaminated as it draws rust-causing moisture and picks up other debris, or it can break down from excess heat. Clean brake fluid is either clear or slightly yellow, while dirty brake fluid may be brown or even black. Old and dirty brake fluid can damage ABS brake systems internally.

The brake lines connect to the master cylinder through a combination valve, which combines a metering and proportioning valve. It regulates the pressure on the front and rear wheels to make sure both sets of brakes are applied simultaneously. A malfunctioning combination valve may cause the wheels to lock up.

Brake pads and shoes can be made of ceramic, metal or organic materials, while the disc rotors and drums they press against are made of metal. Because the pads and shoes create friction to stop the car, they gradually wear down over time and may wear away completely, letting the metal of the calipers and cylinders they are attached to grind against the rotors and drums and damage them. We always suggest replacing pads and rotors on the axle at the same time. These new components will provide the best mating surface for the pads to apply, minimizing the chances of noises or premature failures. Some pads have a metal strip attached that sounds a warning whistle when the pad becomes too worn, but this strip sounds only when the car is in motion and the brakes are not applied.

If you believe that your braking system is beginning to show signs of problems, bring it in to A-LEN Automotive for a complete brake evaluation. We will measure the pad thickness, check for rotor run out, inspect brake lines, check caliper function, and see how the fluid is looking. One thing our shop is able to do that most shops cannot is provide brake line repair. We are able to do this either on or off the vehicle depending on the application. Brake lines can get very expensive to repair if you have to buy the whole line, we are able to save our customers a substantial amount of money by providing this service. Just ask one of our team members at the front desk!
