Inspection service:
- Always consider brake pad wear when checking
brake fluid level. When driving, a slight drop in
brake fluid level results from normal wear and
automatic adjustment of brake pads.
- If brake fluid level is at minimum marking or
slightly above, brake pads are close to wear
limit, it is not necessary to add fluid.
- If brake pads are new or well away from wear
limit, brake fluid level must be between min. and
max. markings.
- If brake fluid level has dropped below min.
marking, check brake system before adding
brake fluid.
