WARNING:
Clean dust on caliper and brake pads with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:

While removing cylinder body, do never 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. In this case, hang cylinder body with 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 shims and shim covers as a set when replacing brake pads.

Keep rotor clean from brake fluid.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft
pedal occurs at very low mileage. Refer to BR-39, "
BRAKE BURNISHING PROCEDURE" .
Removal and Installation of Brake PadBFS000C4
REMOVAL

When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake
fluid level in reservoir tank because brake fluid will return to
master cylinder reservoir tank.

which were marked at the time of removal when reusing
disc rotor.
2. Install brake caliper assembly to vehicle, and tighten torque
member mounting bolts to the specified torque. refer to BR-33,
"Components" .
CAUTION:
Before installing torque member to vehicle, oil and grease
on washer seats on setting knuckle and torque member.
3. Install L-shaped pin of brake hose to caliper assembly as shown
in the figure, and then tighten union bolt to the specified torque.
Refer to BR-33, "
Components" .
CAUTION:

Do not reuse copper washer for union bolt.

Securely install brake hose to protrusion on caliper
assembly.
4. Refill with new brake fluid and bleed air. Refer to BR-10, "
Bleed-
ing Brake System" .
5. Check rear disc brake for drag.

Disassembly and Assembly of Brake Caliper AssemblyBFS000C6
NOTE:
Do not remove torque member, pads, shims, shim covers, and pad retainers when disassembling and assem-
bling cylinder body.
DISASSEMBLY
1. Remove caliper assembly from vehicle. Refer to BR-35, "Removal and Installation of Brake Caliper
Assembly" .
2. Using a flat-bladed screwdriver remove retaining ring from cylin-
der body as shown in the figure.
3. Place a wooden block as shown in the figure, and blow air from
union bolt mounting hole to remove piston and piston boot.
CAUTION:
Do not get you fingers caught in piston.
4. Using a flat-bladed screwdriver remove piston seal from cylinder
body.
CAUTION:
Be careful not to damage a cylinder inner wall.

INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check inside surface of cylinder for score, rust wear, damage or foreign materials. If any of the above con-
ditions are observed, replace cylinder body.

Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine emery
paper. Replace cylinder body if necessary.
To r q u e M e m b e r
Check for wear, cracks, and damage. If damage or deformation is present, replace torque member.
Piston
CAUTION:

Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials
are stuck to sliding surface.

Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the
above condition are observed.
Sliding Pin Bolts and Sliding Pin Boots
Check sliding pin bolts and sliding pin boots, for wear, damage and cracks. If damage or deformation is
present, replace the applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to piston seal, and install
them to cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boot. Cover piston end with piston
boot, and install cylinder side lip on piston boot properly into the
groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston, and press piston into cylinder body
by hand to assemble piston side lip on piston boot properly into
groove on piston.
CAUTION:
Press piston evenly and vary the pressing point to prevent
cylinder inner wall from being rubbed.

4. Fix piston boot with retaining ring.
CAUTION:

Make sure boot is firmly in cylinder body groove on.

Do not reuse retainer ring.
5. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease to between shim and shim cover. Install inner shim, inner
shim cover to inner pad, and outer shim, outer shim cover to
outer pad.
6. Install pad retainers and, inner pad assembly and outer pad
assembly to torque member.
CAUTION:
Securely assemble pad retainer so that it is not being lifted
up from torque member.
7. Install sliding pin boot to torque member.
8. Press in piston until pads can be installed, and then install cylin-
der body to torque member. Use a disc brake piston tool (commercial service tool) to easily press piston
in.
9. Install cylinder body to torque member, and then tighten sliding pin bolt to the specified torque. Refer to

DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that axle end play is within
the specification before measuring runout. Refer to RAX-3,
"WHEEL BEARING INSPECTION" .
3. If runout is outside the limit, find minimum runout point by shift-
ing mounting positions of disc rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
BRAKE BURNISHING PROCEDURE
Burnish brake pad or lining contact surfaces of rotor according to following procedure after refinishing or
replacing drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:

Be careful of vehicle speed because 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.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Measurement point: At a point 10 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.050 mm (0.0020 in) or less
