INSPECTION
1. INSPECT BRAKE LINE PIPES AND BOOTS
HINT:
Inspect in a well±lighted area. Inspect the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before inspecting the front
brake.
(a) Check all brake lines and hoses for:

Damage

Wear

Deformation

Cracks

Corrosion

Leaks

Bends

Twists
(b) Check all clamps for tightness and connections for leak-
age.
(c) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT AND REAR BRAKE PADS AND
DISCS
(Front pads: See page BR±25)
(Rear pads: See page BR±34)
HINT:
If a squealing or scraping noise occurs from the brake during
driving, check the pad wear indicator.
If there are traces of the indicator contacting the disc rotor, the
disc pad should be replaced.
