INSPECTION
1. INSPECT BRAKE LINE PIPES AND HOSES
HINT:
Check in a well lighted area. Check the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before checking 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 BRAKE PADS AND DISCS
(See page BR±29 )
HINT:
If a squealing or scraping noise comes from the brake during,
check the pad wear indicator to see if it is contacting the disc
rotor. If so, the disc pad should be replaced.
3. INSPECT BRAKE LININGS AND DRUMS

7. INSTALL PAD SUPPORT PLATES
Install the 2 pad support plates.
NOTICE:
