MAINTENANCE
Brakes
The front and rear brakes are hydraulic disc type brakes. Press down on the brake pedal to
engage the brakes. See page 29.
Brake Fluid
Inspect the brake system routinely. Inspect the level of the brake fluid before each operation.
WARNING! After opening a bottle of brake fluid, always discard any unused portion. Never store or
use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The
moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade
and the possibility of accident or severe injury.
Change the brake fluid every two years and any time the
fluid becomes contaminated, the fluid level is below the
minimum, or if the type and brand of the fluid in the
reservoir are unknown. Use only DOT 4 brake fluid.
1. Position the vehicle on a level surface.
2. View the brake fluid level at the reservoir in the
driver’s side wheel well. The level should be
between the upper (MAX) and lower (MIN) level
lines.
3. If the fluid level is lower than the upper level line,
add brake fluid to the upper (MAX) line.
4. Apply the brake forcefully for a few seconds and
check for fluid leakage around the fittings.
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 friction pads for wear, damage and
looseness.
4. Check brake discs for signs of cracks, excessive
corrosion, warping or other damage. Clean any grease
using an approved brake cleaner or alcohol.
WARNING! Do not apply WD-40 or any petroleum product to
brake discs. These types of products are flammable and may
also reduce the friction between the brake pad and caliper.
5. Inspect the brake disc spline and pad wear surface for
excessive wear. Change pads when worn to 0.030"
(0.762 mm).
