How do I know if my brake fluid needs to be changed?

Brake fluid absorbs moisture. Water in brake fluid can boil during repeated or extended braking, creating air bubbles which reduce braking effectiveness. Water also can corrode metal brake lines. Change your brake fluid when:
  • A Brake Fluid Tester shows excess moisture
  • Fluid is dirty or rust-colored (it should be clear or translucent)
  • Brake pedal feels mushy or requires a lot of pressure (possible air bubbles)
  • You've reached the miles or years your owner's manual recommends for fluid changes
Not returnable once opened.
