Caution
Danger of contamination and paint damage from escaping brake fluid.
- If the brake pads are worn out and brake fluid is filled, the brake fluid may overflow if the pistons in the brake cylinder are 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 Brake Charger/Bleeder Unit -VAS5234- to extract brake fluid from brake fluid reservoir.
