When it comes to vehicle safety, nothing is more critical than brakes.Grease Monkey™ centers offer Brake Service and Brake Fluid Flush.
How Do Brakes Work?
When you step on the brake pedal, the master cylinder compresses the brake fluid, sending pressure through the brake lines:
- On disc brakes, the fluid pressure causes the calipers to pinch brake pads into contact with the disc brake rotor, which is attached to the wheel, forcing it to slow down or stop.
- With drum brakes, the fluid is forced into the wheel cylinder, which pushes the brake shoes out. The brake shoes are pressed against the drum, which is attached to the wheel, causing the wheel to stop.
In either case, the friction linings (pads or shoes) convert the forward motion of the vehicle into heat. Heat is what causes the pads or shoes to eventually wear out and require replacement.
Grease Monkey’s Brake Service
A brake service at Grease Monkey includes a free, thorough inspection of the vehicle’s brake system components and a short interview with the vehicle owner on the history and any symptoms of the brake system. If maintenance or repair is indicated, you will receive a free written estimate for your review and authorization. Once authorized, the service includes cleaning the serviceable parts, and replacing worn components with quality new parts. Resurfacing the rotors is also included in each service level, which is recommended when the pads are replaced. We also lubricate the brake system sliding mechanisms and hardware so your brake system will continue to perform.
How Often to Perform a Brake Service
Routine maintenance of brake components is a cost effective way to keep your brake system operating safely and decrease long term brake repair costs. It’s a good idea to have timely inspections, such as during a tire rotation or at recommended mileage intervals, so you know the condition of your brakes. You can replace components that are wearing out before the brake pads or shoes wear to the point of metal to metal contact. Replacing the wearing components before additional parts are needed can save you long term repair costs. You should also have your brake system inspected anytime you think you’re experiencing an issue with your brakes.
Brake Fluid Flush
How Does Brake Fluid Work?
Brake fluid is essential to the brake system, providing the hydraulic force to stop the vehicle. Just like engine oil and other critical fluids, brake fluid is formulated with additives that inhibit corrosion, but those additives break down over time. Once the inhibitors are depleted, the brake system is unprotected and vulnerable to corrosion and contamination from particulates, including copper. The presence of these particulates in the fluid can lead to damaged components. The result can be longer stopping distances and in severe cases, total brake system failure.
Grease Monkey’s Brake Fluid Flush
Often overlooked, brake fluid flushing and fluid replacement is a recommended maintenance service. Brake fluid is not maintenance free! It requires periodic testing, and replacement when indicated. The first step of a Grease Monkey Brake Fluid Flush is to test the vehicle’s brake fluid for copper. If the test shows copper levels at or above a specified level, service is needed. The 20-30 minute Brake Fluid Flush clears out all old, worn-out, oxidized, and/or contaminated brake fluid, and replaces it with fresh, new brake fluid. The process also removes moisture, condensation, and air from the brake system.
How Often to Perform a Brake Fluid Flush
You can’t tell brake fluid condition by color, time or mileage. It has to be tested. Testing for copper, and replacement when indicated, is supported by industry experts such as the Motorist Assurance Program (MAP), the National Highway Traffic Safety Administration (NHTSA), and the Automotive Maintenance and Repair Association (AMRA). The experts recommend brake fluid testing at the same interval as your owner’s manual recommendations for brake system inspection, and to replace the brake fluid (for most vehicles) when testing shows the copper content exceeds 200 ppm.
