MAINTENANCE
Brakes
The front and rear brakes are hydraulic disc type brakes activated by the
brake pedal. See page 34.
Always check brake pedal travel and the brake fluid reservoir level
before each use of the vehicle. When applied, the brake pedal should
feel firm. Any sponginess would indicate a possible fluid leak or low
brake fluid level, which must be corrected before riding. See page 73 for
brake fluid information.
If you discover any irregularities in brake system operation, including
excessive pedal travel, contact your dealer for proper diagnosis and
repairs.
Operating the vehicle with a spongy brake pedal can result in loss of
braking, which could cause an accident resulting in severe injury or death.
Never operate the vehicle with a spongy-feeling brake pedal.
Brake Inspection
1. Check the brake system
for fluid leaks.
2. Check the brake pedal
for excessive travel or a
spongy feel.
3. Check the brake pads for
wear, damage and loose-
ness.
4. Inspect the brake pad
wear surface for exces-
sive wear.
5. Change pads when the
friction material is worn
to .40" (1 mm).
6. Check the surface condi-
tion of the brake discs.
Measure the thickness of
the front and rear discs.
Replace a disc if the
thickness is less than .170” (4.32 mm).
7. Check brake system hoses and fittings for cracks, deterioration,
abrasion and leaks. Tighten any loose fittings and replace any worn
or damaged parts.
