Brake fluid is important for the operation of a car’s brakes. When you push the brake pedal, the brake fluid causes the brake pads to press against the rotors, making the car slow down and stop. Over time, the brake fluid absorbs air, moisture, sludge and other contaminants and gets dirty. Air in the brake fluid causes braking to feel spongy and considerably reduces braking efficiency. A brake system flush includes removing the existing fluid and moisture out of the system and replacing it with new, clean, fluid. A brake fluid flush make sure proper 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 powerful as a pressure bleeder, this is an industry approved method of bleeding your brakes. It gets the job done and provides 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
Inspect brake pads, rotors and hoses
Test drive car
Please keep an eye on the manufacturer’s upkeep schedule and guidelines concerning fluid maintenance. It is a good practice to change brake fluid every 24,000 miles or 36 months. Always use a fluid recommended by your vehicles manufacturer (do not use silicone based brake fluids if your car needs regular brake fluid).
Common symptoms 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 regularly flush your brake system, it will end up costing you more money down the road. As the fluid becomes contaminated, it will eventually cause brake system parts to fail and leak. This will also result in diminished brake system performance, causing a safety concern.
