Caution
Danger of contamination and paint damage from
escaping brake fluid.
- If the brake pads are worn out and unnecessary brake
fluid was filled, the brake fluid may overflow, when the
brake caliper pistons in the brake cylinders are pressed
back.
- Check the brake fluid level before pressing back the
brake caliper pistons. If there is brake fluid up to the
"MAX" mark, some brake fluid will need to be extracted.
