Hydraulic Brake System

CHECKING/BLEEDING
The hydraulic brake system has been filled and bled at the
factory. To check and/or bleed a hydraulic brake system,
use the following procedure.
1. With the vehicle in a level position and the tires prop-
erly inflated, check the fluid level in the reservoir. If
the level in the reservoir is not above the MIN, add
DOT 4 brake fluid.
2. Depress the brake pedal several times to check for a firm
brake. If the brake is not firm, the system must be bled.
3. To bleed the brake system, use the following procedure:
A. Remove the cover and fill the reservoir with DOT
4 brake fluid.
B. Install and secure the cover; then slowly press the
brake pedal several times.
C. Install one end of a clear hose onto the bleed screw
farthest from the cylinder (right rear) and direct the
other end into a container; then while holding
slight pressure on the brake pedal, open the bleed
screw and watch for air bubbles. Close the bleed
screw before releasing the brake pedal. Repeat this
procedure until no air bubbles are present.
WT065A
 NOTE: During the bleeding procedure, watch the
reservoir very closely to make sure there is always a
sufficient amount of brake fluid. If the fluid level gets
low in the reservoir, refill the reservoir before the
bleeding procedure is continued.
D. Repeat step C until the brake pedal is firm.
E. At this point, perform step B, C, and D on the left
rear bleed screw; then move to the right front bleed
screw and follow the same procedure. Finish with
the left front bleed screw.
4. Carefully check the entire hydraulic brake system
that all hose connections are tight, the bleed screws
are tight, the protective caps are installed, and no
leakage is present.
This hydraulic brake system is designed to use DOT 4
brake fluid only. If brake fluid must be added, care must be
taken as brake fluid is very corrosive to painted surfaces.
INSPECTING HOSES
Carefully inspect the hydraulic brake hoses for cracks or
other damage. If found, the brake hoses must be replaced.
CHECKING/REPLACING PADS
The clearance between the brake pads and brake discs is
adjusted automatically as the brake pads wear. The only
WT012A
maintenance that is required is replacement of the brake
pads when they show excessive wear. Check the thickness
of each of the brake pads as follows.
1. Remove a front wheel.
2. Measure the thickness of each brake pad.
