The brake system is actually composed of two kinds of systems—Hydraulics and Friction Materials. Here’s what happens within these systems between the time your foot hits the brake pedal and your car stops.
When pressure is applied to the brake pedal, the master cylinder creates hydraulic pressure which pushes brake fluid to the wheel brakes.
Brake Lines and Hoses
Steel brake lines and high pressure rubber hoses are the avenues through which the pressurized brake fluid travels.
Wheel Cylinders and Calipers
These are the hydraulic cylinders that apply pressure to the friction materials, causing your car to stop.
Disc Brake Pads and Drum Brake Shoes
These brake linings are composed of high temperature materials that create the friction that stops your car.
Types of Brakes
Disc brakes consist of a Disc Brake Rotor, which is attached to the wheel, and a Caliper, which holds the Disc Brake Pads. Hydraulic pressure from the Master Cylinder causes the Caliper Piston to clamp the Disc Brake Rotor between the Disc Brake Pads. This creates friction between the pads and rotor, causing your car to slow down or stop.
Drum brakes consist of a Brake Drum attached to the wheel, a Wheel Cylinder, Brake Shoes, and Brake Return Springs. Hydraulic pressure from the Master Cylinder causes the Wheel Cylinder to press the Brake Shoes against the Brake Drum. This creates friction between the shoes and drum to slow or stop your car.
The Parking Brake uses Cables to mechanically apply the brakes (usually the rear brake.) This is used to prevent the car from rolling when not being driven.
Anti-Lock Brakes: A System Built For Safety
Computer-controlled anti-lock braking systems (ABS) are a recently developed safety feature. When sudden stops are made, the ABS prevents wheel lock-up. The system is comprised of wheel-speed sensors that monitor wheel rotation, computer-controlled hydraulics that pulse the brakes on and off onboard and the on-board computer.
BRAKES & BRAKE REPAIR
At Integrity Auto Repair, we want our Eugene customers to have the opportunity to feel comfortable in their vehicle. You can leave the repairs and services to our professionals, but please don’t hesitate to ask us questions about why a service is needed or how it occurred. Give us a call at 541-343-1545, and we will be happy to speak with you. Here is some valuable information on brake issues and corrective services Integrity Auto Repair offers.
Brake Pad & Shoe Replacement
Brake pad problems can usually be identified by squealing brakes. If your brake pads deteriorate completely, you’ll hear a grinding metal-on-metal sound when braking, meaning that it’s too late and you’re ruining your rotors or drums! Those with knowledge of auto repair may be able to fix this at home, but you should always see an auto repair professional immediately if you have brake problems.
In a disc brake system, rotors are attached to your vehicle’s wheels. When the brake pads grip the rotor, they bring both the rotor and wheels to a stop. However, the friction causes grooves and cracks to appear over time. Resurfacing brings the rotor back to a “like-new” condition, reducing squealing and wobbling. Integrity Auto Repair will give your rotors a thorough inspection and recommend your best course of action.
The brake caliper houses your brake pads and fits around the rotor like a clamp, pressing the pads against the rotor when you brake. A brake caliber problem could cause uneven braking, making your car slide forward when you brake. Uneven braking can also cause your vehicle to slide out of control in bad weather conditions, so contact Integrity Auto Repair as soon as possible.
A brake hose is a tube carrying pressurized brake fluid from the master cylinder to the brakes. A crushed hose can cause a lagged or slow brake, and a leak in the hose can cause the brake, or the entire brake system, to fail. These don’t need to be replaced often but should be replaced at the first sign of cracking or wear.
Brake Fluid Flushes
Brake fluid will absorb water from the air over time, causing the brake system to become less effective and the fluid to become corrosive, possibly damaging the system. It is important to perform a brake fluid flush regularly to ensure that your vehicle is using fresh fluid. Talk to our technicians at Integrity Auto Repair about when it’s time for a brake fluid flush.
Wheel bearings are found inside of wheels, allowing the wheels to spin freely, and are connected to the brake system. They can become worn over time, causing a vibrating suspension and noisy rubbing as the car is driven. If they break completely, the vehicle will become very difficult to control and unsafe to drive. Replacement interval for wheel bearings varies greatly, but they should be checked for leaks and wear periodically. Integrity Auto Repair can make sure that your bearings are in good shape and let you know if they need replacement.
Anti-Lock Brake System
Anti-lock Brake Systems (ABS) ensure that the wheels don’t stop rotating during braking, preventing the car from skidding and offering greater control. If your ABS light comes on, visit Integrity Auto Repair where we will be happy to diagnose and fix the problem.
