CAUTION:

Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed
air.

While removing brake pad or cylinder body, do not depress brake pedal because piston will pop
out.

It is not necessary to remove torque member mounting bolts and brake hose except for disassem-
bly or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake
hose is not under tension.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Keep rotor free from brake fluid.

When replacing brake pad, replace shim with a new one.
Removal and Installation of Brake PadEFS006JP
REMOVAL
1. Remove tires from vehicle.
2. Remove sliding pin bolt (lower side).
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.
INSTALLATION
1. Apply AS-880N grease or equivalent to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.
CAUTION:

When installing pad retainer, attach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.
CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-24, "
Compo-
nents" .

3. Remove sliding pins and sliding pin boots from torque member.
4. Place a wooden block as shown, and blow air from union bolt
mounting hole to remove piston and piston boot.
CAUTION:
Do not get fingers caught in the piston.
5. Remove piston seal with a flat-bladed screwdriver.
CAUTION:
Be careful not to damage the inner wall of cylinder.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, wear, and damage. Replace cylinder body as necessary.
CAUTION:
Clean cylinder body using new brake fluid. Never use mineral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. Replace torque member as necessary..
Piston
Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. Replace applicable
part as necessary.
ASSEMBLY
CAUTION:
When assembling, use only specified rubber lubricant.
1. Apply polyglycol ether based lubricant to new piston seal and
install them to cylinder body.

2. Apply rubber grease to piston boot and apply brake fluid to pis-
ton. Cover the piston end with piston boot, and install cylinder-
side lip on piston boot properly into groove on cylinder body.
3. Press piston into cylinder body by hand to assemble piston-side
lip on piston boot properly into a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.
4. Install sliding pins and sliding pin boots to the torque member.
5. If pads, shims and pad retainers were removed, install them to torque member. Refer to BR-25, "
INSTAL-
LATION" .
6. Install cylinder body to torque member.
7. Install sliding pin bolts.
8. Install caliper assembly to vehicle. Refer to BR-26, "
INSTALLATION" .
9. Tighten sliding pin bolts to specified torque. Refer to BR-24, "
Components" .
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. Replace applicable part as neces-
sary.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub 2 or more positions.
2. Using a dial indicator, check runout.
CAUTION:
Make sure that wheel bearing axial end play is within the
specifications before measuring runout. Refer to FA X -5 ,
"FRONT WHEEL BEARING INSPECTION" .
3. If runout is outside the limit, find the minimum runout point by
shifting the mounting positions of disc rotor and wheel hub by
one hole.

Removal and Installation of Drum Brake AssemblyEFS006JU
REMOVAL
1. Remove tire from the vehicle.
2. With the parking brake lever released, remove the brake drum. If it is difficult to remove brake drum,
remove as follows:
a. Press up adjuster lever with a wire or equivalent from plug hole
(plug hole at the side of wheel cylinder) on the back plate as
shown in the figure. Turn frame of adjuster assembly with a flat
bladed screw driver in the direction that narrows frame to narrow
enlarged brake shoe.
