CAUTION:

There is a risk of contamination and paint damage from escaping brake fluid.

  • If the brake pads are worn out and brake fluid is filled unnecessary, the brake fluid may overflow, causing the pistons in the brake cylinders to be pressed back.
  • Check the brake fluid level before pressing back the pistons. If there is brake fluid up to the "MAX" mark, some brake fluid will need to be extracted.
  • Use the :VAS5234  to extract brake fluid from the brake fluid reservoir.
