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, 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 within the
specification before measuring runout. FAX-5 , "
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.
4. If runout is still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and
705” or equivalent).
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
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.
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 the brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Measurement point: At a point 10.0 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.040 mm (0.0016 in) or less

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
1. Remove tyres from vehicle.
2. Remove upper sliding pin bolt.
3. Suspend cylinder body with wire, and remove pads, pad retainers and shims, and shim covers from
torque member.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the bosh side of inner shim and outer
shin, install inner shim, inner shim cover to inner pad, and outer shim, outer shim cover to outer pad.
2. Install pad retainers and pads to torque member.
3. Press in piston until pads can be installed, and then install cylin-
der body to torque member.
NOTE:
Using a disc brake piston tool (commercial service tool) to easily
press piston in.
CAUTION:
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.
4. Install upper sliding pin bolt and tighten to the specified torque. Refer to BR-33, "
Components" .
5. Secure disc rotor with wheel nut. Depress brake pedal a few times until it gets a responsive touch.
6. Check rear disc brake for drag.
7. Install tyres to vehicle.
Refer to GI-10, "Components" and the followings for the symbols in the figure.
1: Apply rubber grease.
2: Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease.
3: Apply polyglycol ether based lubricant.
