(a) Check the fluid level.

NOTICE:

If using a dropper to adjust the fluid amount, make sure that the dropper has not been used with mineral oils, water or deteriorated brake fluid. Sealed areas may deteriorate and lead to fluid leaks, or the fluid may deteriorate and lead to decreased efficiency.

• If the brake fluid level is lower than the MIN line, inspect for brake fluid leaks and brake pad wear. If necessary, refill the reservoir with brake fluid to the MAX line after repair or replacement.
• The brake fluid level must always be adjusted to the MAX line.
