MAINTENANCE
Daily Brake Performance Test
NOTICE: To ensure correct braking performance, all
periodic maintenance, inspections and procedures
must be performed. See SCHEDULED MAINTE-
NANCE CHART on page 166. A Daily Brake Perfor-
mance Test must be performed, and the entire brake
system must be serviced in accordance with the
SCHEDULED MAINTENANCE CHART.
The brake system must be bled whenever any part
of the brake system has been replaced.
The STAMPEDE 900 has front and rear hydraulic disc
brakes. Perform scheduled maintenance on the brake
system at the intervals indicated in the Scheduled Mainte-
nance Chart.
Check the brake fluid level before each operation. Test
the brakes for function before each use.
Press the brake pedal. The pedal should have some ini-
tial free play, and then become resistant. This indicates
proper performance.
If the brake pedal has a soft feel or loses resistance, per-
form a brake system inspection.
Brake System Inspection
1. Check brake fluid level.
2. Check the brake system for fluid leaks.
3. Check the brake pedal for excessive travel or a
spongy feel.
4. Check the brake calipers for looseness.
5. Check the brake pads for wear or damage. Replace
the brake pads if worn to 3/64 inch (1 mm) or less
(Ref. Fig. 2).

6. Check the brake rotors for cracks, corrosion, warping
or other damage.
7. Clean any grease found on the brake discs with an
approved brake cleaner or alcohol.
Never apply WD-40 or any petro-
leum product to the brake discs.
These products are flammable and
can also reduce the friction between the brake pad
and caliper and increase the possibility of an acci-
dent that can result in severe injury or death.
Do not allow brake fluid to contact the brake pads. If
the brake pads become wet with hydraulic fluid,
wipe the brake pads and rotor until they are dry.
Complete brake failure usually indicates a loss of hydrau-
lic fluid pressure.
If the brake pedal has a soft feel, bleed the brakes to
remove air from the brake system.
A brake pedal that loses resistance indicates a leak in the
hydraulic system:
1. Check brake fluid level. If the fluid is low, inspect the
system for leaks.
a. Check for leaks by applying pressure to the
pedal gradually and steadily.
b. If pedal sinks very slowly to the floor, the system
has a leak along the brake lines or at the hydrau-
lic cylinder. If no external leaks are apparent, the
problem is likely inside the master cylinder.
3. If leaks are found, repair the leaks in the brake sys-
tem, or repair or replace the master cylinder.
4. Bleed the brakes to remove air from the brake sys-
tem.
NOTICE: Do not allow brake fluid to contact painted
surfaces.
Brake Fluid
When adding or changing brake
fluid, always use brake fluid from an
unopened bottle. After opening a
bottle of brake fluid, always discard the unused por-
tion. Do not store, or use from an opened bottle.
Brake fluid rapidly absorbs moisture from the air.
The moisture causes the boiling temperature of the
brake fluid to drop. This can lead to premature brake
fade and the possibility of an accident that can
result in severe injury or death.
The brake fluid reservoir is located under the cowl near
the driver side front wheel. Remove the panel from the
cowl to access the reservoir.
