MOBILE BRAKE FLUID FLUSH AT YOUR HOME OR OFFICE

Most brake fluid used in production vehicles today is glycol-based. This type of fluid is hygroscopic, which means it naturally absorbs moisture that’s present in the air at all times. According to engineers, that absorption rate is approximately 1.5 to 3% a year in areas of normal atmospheric pressures. In humid climates, that rate can climb even higher. Moisture will always find its way into the lines through microscopic pores in brake hoses, seams, joints, and seals - there’s simply no way to avoid it. As brake fluid absorbs more and more water, it will begin to boil at lower and lower temperatures.

WHAT IS BRAKE FLUID FLUSH?

Brake fluid is essential 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 contaminated. Air in the brake fluid causes braking to feel spongy and significantly 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 ensures proper brake system performance and increases the lifespan of your brake system components.

HOW IS BRAKE FLUID FLUSH DONE?

  1. Remove contaminated brake fluid
  2. Add new brake fluid
  3. Bleed the brakes
  4. Clean any surfaces where brake fluid has spilled during the bleeding process
  5. Check for fluid leaks
  6. Inspect brake pads, rotors and hoses
  7. Test drive car

RECOMMENDATIONS

Follow the manufacturer’s maintenance schedule and guidelines regarding fluid maintenance. It is a good practice to change brake fluid every 24,000 miles or 36 months.
