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:
lWhile removing cylinder body, do not depress brake pedal because piston will pop out.
lIt 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 a wire so as not to stretch
brake hose.
lDo not damage piston boot.
lIf any shim is subject to serious corrosion, replace it with a new one.
lAlways replace shim as a set when replacing brake pad.
lKeep rotor out of brake fluid.
Removal and Installation of Brake PadEFS005T0
REMOVAL
1. Remove tyre from vehicle.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire. Remove pad assembly and pad retainer from torque member.
CAUTION:
When removing the pad retainer from the torque member, lift it in the direction indicated by the
arrow in the figure so that it does not deform.
INSTALLATION
1. Install inner shim to inner pad, and outer shim to outer pad.
2. Install pad retainers and pad assembly to torque member.
3. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
CAUTION:
lWhen installing pad retainer, attach it firmly so that it
does not flat up higher than torque member, as shown in
the figure.
lIn the case of replacing pad with new one, check a brake
fluid level in the reservoir tank because brake fluid
returns to master cylinder reservoir tank when pressing
piston in.
4. Install lower sliding pin bolt and tighten to the specified torque. Refer toBR-24, "
Components".
5. Check front disc brake for drag.
6. Install tyre to vehicle.

CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.
Torque Member
Check torque member for wear, cracks, and damage. If a malfunction is detected, replace applicable part.
Piston
Check piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable part.
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt and Sliding Pin Boot
Check sliding pin, sliding pin bolt and sliding pin boot for wear, damage, and cracks. If a malfunction is

ASSEMBLY
CAUTION:
When assembling, use only rubber lubricant specified below.
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
2. Apply brake fluid to piston and apply rubber grease to piston
boot.Coverthepistonendwiththepistonboot,andtheninstall
cylinder side lip of the piston boot securely into the groove on
cylinder body.
3. Insert piston into cylinder body by hand and insert piston boot
piston-side lip into the piston groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
4. Install sliding pin and sliding pin boot to torque member.
5. If pad assemblies are removed, install pad assemblies to torque member. Refer toBR-25, "
Removal and
Installation of Brake Pad".
6. Install cylinder body to torque member, and then tighten sliding pin bolt to the specified torque. Refer to
BR-24, "
Components".
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheel hub. (2 or more positions)
2. Check runout using a dial indicator.
[measured at 10 mm (0.39 in) inside the disc edge]
CAUTION:
Make sure that wheel bearing axial end play is within the
specifications before measuring runout. Refer toFAX-5,
"WHEEL BEARING INSPECTION".
3. If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.
4. If runout is still out of the specification, refinish the disc rotor with
on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent). Or replace the disc rotor.

Thickness Inspection
Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.
BRAKE BURNISHING PROCEDURE
Burnish the new braking surface according to the following procedure after refinishing or replacing rotors, after
replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).
2. Use medium brake pedal foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).
Adjust brake pedal foot pressure such that vehicle stopping time equals 3 to 5 seconds.
3. To cool brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.
4. Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.Standard thickness : 28.0 mm (1.102 in)
