Removal and Installation of Brake Pads
WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the
hazard of air borne
particles or other materials.
CAUTION:
- While removing brake pads, do not depress brake pedal because
piston will pop out.
- It is not necessary to remove bolts on torque member and brake
hose except for disassembly or
replacement of caliper assembly. For brake pad removal, hang cylinder body
with a wire so as not to
stretch brake hose.
- Do not damage piston boot.
- If any shim is subject to serious corrosion, replace it with a
new one.
- Always replace shim and shim cover as a set when replacing
brake pads.
- Keep rotor and pads free from grease and brake fluid.
- Burnish the brake pads and disc rotor contacting surfaces,
after refinishing or replacing rotors, after
replacing pads, or if a soft pedal occurs at very low mileage. Refer to
BR-31, "Brake Burnishing Procedure".
REMOVAL
- Remove front wheel and tire using power tool. Refer to WT-60,
"Adjustment".
- Partially drain brake fluid from master cylinder.
- Remove the upper and lower sliding pin bolts.
NOTE:
Note the sliding pin orientation during removal. The lower sliding pin
contains a bushing.
- Remove the brake caliper from the torque member. Leaving the brake
hose attached, reposition the brake
caliper aside with wire.
- Remove anti-rattle clips, pads, shims, and shim covers from torque
member.
INSTALLATION
- Apply Molykote AS-880N grease or equivalent between the inner and outer
shims and the back of the
brake pads.
- Install the inner and outer shims and shim covers to the inner pad
and outer pad.
CAUTION:
Do not get grease on the inner and outer pad friction surfaces.
- Apply Molykote 7439 grease (A) or equivalent to the pad
retainer and attach the pad retainer to the torque member.
- Install the assembled inner and outer shims, shim covers, pads
and anti-rattle clips to the torque member.
CAUTION:
Do not get grease on the inner and outer pad or rotor friction
surfaces.
- Press piston into cylinder body using suitable tool, then install
the cylinder body on the torque member.
CAUTION:
When replacing pads with new set, check the brake fluid
level in the reservoir tank because brake fluid returns to the
master cylinder reservoir tank when pressing in the piston.
- Install the upper and lower sliding pin bolts (2) and tighten it
to
the specified torque.
- Check front disc brakes for drag.
- Install the front wheel and tire. Refer to WT-60, "Adjustment".
- Check brake fluid level and refill as necessary. Refer to BR-16,
"Inspection".
Brake Burnishing Procedure
Burnish contact surfaces between disc rotors and pads according to following
procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low
mileage.
CAUTION:
- Be careful of vehicle speed because the brake does not operate
easily until pad and disc rotor are
securely fitted.
- Only perform this procedure under safe road and traffic
conditions. Use extreme caution.
- Drive vehicle on straight, flat road.
- Depress brake pedal with the power to stop vehicle within 3 to 5
seconds until the vehicle stops.
- Drive without depressing brake for a few minutes to cool the
brake.
- Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

Removal and Installation of Brake Caliper and Rotor
WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the
hazard of air borne
particles or other materials.
CAUTION:
- When removing and installing the cylinder body, do not depress
the brake pedal because the piston
will pop out.
- Do not damage the piston boot.
- Keep the brake rotor free from grease and brake fluid.
- Refill the brake reservoir with new brake fluid only.
- Do not reuse the drained brake fluid.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings
to prevent fluid from spilling.
REMOVAL
- Remove front wheel and tire using power tool. Refer to WT-60,
"Adjustment".
- Secure the disc rotor using a wheel nut.
- Remove the reservoir cap.
- Remove the union bolt (1) and disconnect the brake hose from the caliper
assembly. Discard the copper
sealing washers.
CAUTION:
Do not reuse copper sealing washers.
- Remove the upper and lower sliding pin bolts.
NOTE:
Note the sliding pin orientation during removal. The lower sliding pin
contains a bushing.
- Remove the brake caliper.
- Remove the torque member bolts (2), and the torque member.
CAUTION:
Do not drop the brake pads.
- Remove the disc rotor. If reusing the disc rotor, apply a matching
mark as shown for installation.
CAUTION:
Put matching marks on wheel hub assembly and disc rotor,
if reusing the disc rotor.
INSTALLATION
- Install the disc rotor. If reusing the disc rotor, align the
matching
mark on the disc rotor and wheel hub assembly for installation
as shown.
CAUTION:
Align the matching marks on wheel hub assembly and disc
rotor, if reusing the disc rotor.
- Install the brake caliper assembly, and tighten the torque member bolts
to the specified torque.
CAUTION:
Do not allow oil or any moisture on all contact surfaces between steering
knuckle and caliper
assembly, bolts, and washer.
- Install the brake hose with two new copper sealing washers (1),
using the L-shaped pin for alignment as shown, then tighten the
union bolt (A) to the specified torque.
CAUTION:
Do not reuse copper sealing washers.
- Refill the brake hydraulic system with new brake fluid and bleed air.
Refer to BR-16, "Bleeding Brake System".
- Check the front disc brakes for drag.
- Install the reservoir cap.
- Install the front wheel and tire. Refer to WT-60, "Adjustment".
