Brake maintenance is one of the most important factors ensuring the safety of your vehicle, and it’s essential to appreciate the many moving parts that make up your brake system.
The brake dashboard light glows amber or red, brake pedal feels spongy, brake pedal presses closer to the floor than usual
squeaky, grinding noise is heard, and/or the vehicle pulls to one side when the brakes are applied.
Your braking system is a complex assembly of mechanical, electronic and hydraulic components which use friction to slow and stop a moving vehicle. When the brake pedal is applied, the pressure on the brake pedal moves a piston in the master cylinder, forcing the brake fluid from the master cylinder through the brake lines and flexible hoses to the calipers and wheel cylinders. The force applied to the brake pedal produces a proportional force on each of the pistons.
The calipers and wheel cylinders contain pistons, which are connected to a disc brake pad or brake shoe. Each output piston pushes the attached friction material against the surface of the rotor or wall of the brake drum, thus slowing down the rotation of the wheel. When pressure on the pedal is released, the pads and shoes return to their released positions. This action forces the brake fluid back through the flexible hose and tubing to the master cylinder.
Disc Brakes are comprised of a disc (rotor), a caliper assembly, and pads. The caliper is connected to the master cylinder through tubes, hoses and valves that conduct brake fluid through the system.
Drum Brakes are comprised of a drum and backing plate, a hub or axle assembly, brake shoes, and wheel cylinder. The wheel cylinder is connected to the master cylinder through tubes, hoses and valves that dispenses brake fluid through the system.
Brake fluid is a hydraulic fluid used to transfer force under pressure from where it is created through hydraulic lines to the braking mechanism near the wheels. Braking produces extreme heat so brake fluid must have a high boiling point to remain effective and must not freeze under operating conditions.
Don’t Put It Off
Brake pad replacement is the most common repair job simply because brakes are designed to wear out. Your brake pads rub on the brake disc to slow and stop your vehicle, so worn pads are the first part to check. The longer you prolong servicing your braking system, the probability of more costly repairs are looming.
From the pads to fluids, calipers to rotors, discs to ABS sensors, Master Automotive Centers can perform brake repair on any make and model car, truck, or SUV. Call or come by for a complete brake inspection today!
