Brake fluid is vital 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, making the vehicle slow down and stop. Over time, the brake fluid absorbs air, moisture, sludge and other contaminants and becomes contaminated. Air in the brake fluid makes braking to feel spongy and significantly reduces braking efficiency. A brake system flush involves removing the existing fluid and moisture out of the system and replacing it with new, clean, fluid. A brake fluid flush will ensure proper brake system performance and increases the lifespan of your brake system parts.
Bear in mind
A mobile mechanic will make use a hand-held vacuum pump and/or atmospheric pressure to remove the fluid. While this is however not as powerful as a pressure bleeder, this is an industry approved method of bleeding your brakes. It gets the job done and gives the convenience of a mechanic coming to you.
How it works
- Takes out 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 vehicle
It is proper to follow the manufacturer’s maintenance schedule and guidelines regarding fluid maintenance. It is a good practice to replace brake fluid every 24,000 miles or 36 months. Always use a fluid recommended by your car manufacturer (do not use silicone based brake fluids if your vehicle needs regular brake fluid).
What common signs show you may need a brake system flush
- Brake fluid seems black or brown indicating contamination
- Brake pedal feels spongy
- Diminished brake system performance
