Pad ReplacementEFS0017Z
REMOVAL
CAUTION:
When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.
1. Remove master cylinder reservoir tank cap.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
and shims.
INSTALLATION
1. Apply brake grease on back of the pad and both sides of the shim. Install inner shim and inner shim cover
to inner pad, outer shim to outer pad.
2. Install pad retainers to torque member and install pads.
3. Connect cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press piston in until the pads can be installed. Carefully mon-
itor brake master cylinder reservoir fluid level. Brake fluid will return, raising master cylinder res-
ervoir tank fluid level.
4. Insert lower sliding pin bolt and tighten to the specified torque.
5. Check brakes for drag.

Caliper Removal and InstallationEFS00180
REMOVAL
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve while depressing
brake pedal.
3. Remove union bolt and remove brake hose from caliper assem-
bly.
4. Remove union bolts and torque member mounting bolts, and
remove caliper assembly.
5. Remove disc rotor.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Never reuse drained brake fluid.
1. Install disc rotor.
2. Install caliper assembly. Tighten mounting bolts to the specified torque.
CAUTION:
Wipe brake fluid and grease on axle assembly washer seats and caliper assembly mounting sur-
face. Install caliper assembly.
3. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.
CAUTION:

Do not reuse the copper washer for union bolts.

Securely assemble brake hose to protrusions on cylinder body.
4. Bleed air. Refer to BR-9, "
Bleeding Brake System" .
Caliper Disassembly and AssemblyEFS00181
DISASSEMBLY
WARNING:
Be careful not to pinch your fingers in the piston.
CAUTION:
Be careful not to damage the cylinder inner wall.
1. Remove caliper assembly from vehicle.
2. Remove sliding pin from cylinder body. Then remove pads, shims, shim covers, and pad retainers from
caliper assembly.
3. Remove sliding pin boots from torque member.
4. Using flat-bladed screwdriver (as shown in the figure), remove
retaining ring.

5. Place a wooden block as shown in the figure. Blow air into union
bolt mounting hole to remove pistons and piston boots.
6. Using flat-bladed screwdriver, remove piston seals.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.

Check cylinder inner wall for corrosion, wear and damage. If corrosion, wear or damage is detected,
replace the cylinder body.

Minor flaws caused by corrosion or foreign material can be removed by polishing the surface with fine
sandpaper. Replace the cylinder body, if necessary.
To r q u e M e m b e r
Check for wear, cracks and damage. If wear, cracks or damage is detected, replace the applicable part.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear and damage. If corrosion, wear or damage is detected, replace the
applicable part.
Sliding Pin, Pin Bolt and Pin Boot
Check sliding pin and sliding pin boot for wear, damage and cracks. If corrosion, wear or damage is detected,
replace the applicable part.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of the disc rotor for uneven wear, cracks and serious damage. If uneven wear, cracks or seri-
ous damage is detected, replace it.
Run Out Inspection
1. Using wheel nuts, fix the disc rotor to wheels hub. (2 or more positions)

2. Using a dial indicator, check run out.
NOTE:
Make sure that wheel bearing axial endplay is with in the specifi-
cation before measuring runout. Refer to RAX-6, "
On-vehicle
Inspection and Service" (2WD), RAX-10, "On-Vehicle Inspec-
tion" (4WD).
3. If the run out is outside the limit, find the minimum run out point by shifting the mounting positions of disc
rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If the thickness is
outside the standard, replace disc rotor.
ASSEMBLY
CAUTION:
When assembling, do not use rubber grease.
1. Apply rubber lubricant to piston seals, and install them to the cyl-
inder body.
CAUTION:
Do not reuse piston seals.
2. Apply brake fluid to piston boots. Cover piston end with piston
boot. Install cylinder side boot lip properly into groove on cylin-
der body.
CAUTION:
Do not reuse piston boot.
3. Press piston into cylinder body by hand. Assemble piston side
boot lip properly into groove on the piston.
CAUTION:
Press piston evenly and change pressing point to prevent
the cylinder inner wall from being rubbed.Measurement point:
At a point of 10 mm (0.39 in) from the outer
edge of the disc.
Run out limit:
0.07 mm (0.0028 in) or less
