C. Install one end of a clear hose onto the REAR
bleeder screw and direct the other end into a
container; then while holding slight pressure on
the brake pedal, open the bleeder screw and
watch for air bubbles. Close the bleeder screw
before releasing the brake pedal. Repeat this pro-
cedure until no air bubbles are present.
PK103A
NOTE: During the bleeding procedure, watch the

reservoir very closely to make sure there is always a
sufficient amount of brake fluid. When the level falls
below MIN, refill the reservoir before the bleeding
procedure is continued. Failure to maintain a suffi-
cient amount of fluid in the reservoir will result in air
in the system.
D. At this point, perform steps B and C on the
FRONT RIGHT bleeder screw; finally, move to
the FRONT LEFT bleeder screw and follow the
same procedure.
PK104
E. Repeat steps B and C until the brake pedal is
firm.
3. Carefully check the entire hydraulic brake system to
ensure all hose connections are tight, the bleed
screws are tight, the protective caps are installed, and
no leakage is present.
CAUTION
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 sur-
faces.
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
maintenance that is required is replacement of the brake
pads when they show excessive wear. Check the thick-
ness of each of the brake pads as follows.
1. Remove the wheel corresponding to the brake being
checked.
2. If the brake pad friction material has worn to the
point of the wear groove (A) no longer being visible,
replace the brake pads.
PK105A
NOTE: For optimum new brake pad life, the brake

pads and rotors should be replaced as a set.
To replace the brake pads, use the following procedure:
A. Loosen the brake pad retaining pins (A); then
remove the cap screws securing the caliper
holder to the knuckle (B). Remove the retaining
pins and pads from the caliper.
PK106A
B. Install the new brake pads. Coat the threads of
the retaining pins with blue Loctite; then tighten
to 13 ft-lb (17.7 N-m).
C. Secure the caliper holder to the knuckle with
new " patch-lock "
(34 N-m).
cap screws. Tighten to 25 ft-lb
