bodies, such as nails and glass splinters.

- Check that tires are the same type and tread
pattern.

Inspection service:

- Measure tread depth.


Minimum tread depth: 1.6 mm (0.0625 in.)
If tread depth is close to legal permissible
minimum, i.e. if the 1.6 mm high wear indicator
spaced around tire circumference no longer has
any tread pattern, the customer must be in
formed.
Tires should also be checked for scuffing, wear
on one side, porous side walls, cuts, and
fractures.
Any defects found must be reported to the

(0.28 in.).
Thoroughly remove all dirt from wheels.
If pad thickness including backing plate is 7 mm (0.28 in.) or less the
brake pads have reached or exceeded wear limit and must be replaced. - Determine thickness of outer and inner pads by inspecting visually.

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.
