What is a brake system flush?
Brake fluid is important for the operation of a car’s brakes. When you push the brake pedal, the brake fluid makes the brake pads to press against the rotors, causing the car slow down and stop. Over time, the brake fluid absorbs air, moisture, sludge and other contaminants and gets contaminated. Air in the brake fluid makes braking to feel spongy and greatly decreases braking effectiveness. A brake system flush includes removing the existing fluid and moisture out of the system and changing it with new, clean, fluid. Brake fluid flush guarantees appropriate brake system performance and increases the lifespan of your brake system parts.
Facts to Note:
A mobile mechanic will use a hand-held vacuum pump and/or atmospheric pressure to take out the fluid. While it is not as effective as a pressure bleeder, this is an industry accepted method of bleeding your brakes. It gets the job done and gives the convenience of a mechanic coming to you.
How to Fix:
Remove contaminated brake fluid
Add new brake fluid
Bleed the brakes
Clean any surfaces where brake fluid has spilled during the bleeding process
Check for fluid leaks
Examine brake pads, rotors and hoses
Test drive car
Please follow the manufacturer’s upkeep schedule and guidelines regarding fluid maintenance. It is a good practice to change brake fluid every 24,000 miles or 36 months. Always use a fluid prescribe by your vehicles manufacturer (do not use silicone based brake fluids if your car needs regular brake fluid).
Common signs indicating you may need a brake system flush:
Brake fluid appears black or brown indicating contamination
Brake pedal feels spongy
Diminished brake system performance
Importance of this service:
If you do not frequently flush your brake system, it will end up costing you more money down the road. As the fluid becomes contaminated, it will suddenly make brake system parts to fail and leak. This will also lead to reduced brake system performance, causing a safety concern.
