One of the most essential aspects of auto maintenance is keeping up with your vehicle’s brake system. Functional brakes help you, other drivers, as well as any pedestrians stay safe by stopping your wheels from turning. Here, get answers to common brake questions to take better care of this important safety system.

Frequently Asked Questions About Vehicle Brake Systems

How Do My Brakes Work?

Brakes are hydraulic systems. When you hit the brake pedal, a piston in the master cylinder located under the hood of your vehicle activates, sending brake fluid through hoses to each wheel. Fluid hits the wheel calipers, causing them to put pressure on the brake pads and subsequently the rotors. The pads provide the buffer between the calipers and rotors to prevent heat, friction, and warping.

What Are the Signs Indicating the Need For Brake Service?

Your brakes provide numerous warning signs when they need replacing. The most common is screeching or squealing noises whenever you brake, which indicates caliper contact with the rotor. Get the pads replaced to avoid expensive rotor replacements. Other signs include pulling to the left or the right when you drive, signaling uneven pad wear. You may also notice vibrations or grinding noises when you hit the pedal because the pads have worn out, as well as a “spongy” pedal that indicates a leaking brake line.

What Happens During A Brake Inspection?

Every part of the brake system gets checked during an inspection, including the master cylinder, brake lines, pistons, calipers, wheel cylinders, rotors, and wheel bearings. The quality of the pads gets checked as well and replaced if they are wearing thin. Any hose leaks and other problems also get repaired and replaced, such as a warped rotor from excessive caliper contact.

How Long Do Brakes Last?

Brake systems last up to six years depending on factors such as how often you schedule auto maintenance checks and pad replacements. How often you drive and use your brakes also determines how long brakes will last. If you drive every day in stop-and-go city traffic, for example, your system will expire faster than if you drive regularly on highways with minimal traffic.
