2. Using a dial indicator, check runout.
CAUTION:
Make sure that wheel bearing axi al end play is within the
specifications before measuring runout. Refer to FAX-6," On-Vehicle Inspection and Service " .
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 the specific ation, grind rotor on-car using Tool until runout is within the specified limit.
Thickness Inspection Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specifications, replace disc rotor.
ASSEMBLY CAUTION:
When assembling, use only specified lubricant.
1. Apply rubber grease to new piston seal and install on cylinder body.
2. Apply rubber grease (CL25VF) or polyglycol ether based lubri- cant (AD22VK) to piston boot and apply brake fluid to piston.
Cover the piston end with piston boot, and install cylinder-side
lip on piston boot properly into groove on cylinder body. Runout limit
[measured at 10.0 mm (0.394
in) inside the disc edge] : Refer to

6. Install cylinder body to torque member.
7. Tighten sliding pin bolts to specified torque. Refer to BR-25, " Component " .
8. Install the caliper assembly. Refer to BR-28, " Removal and Installation of Brake Caliper Assembly " .
Brake Burnishing Procedure INFOID:0000000004305914
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, 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 vehicl e within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

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. Turn frame of adjuster assembly with a flat bladed screw
driver in the direction that narrows frame to narrow enlarged
brake shoe.
3. While pushing and rotating the retainer, pull out shoe hold pin, and remove shoe assembly. CAUTION:
Do not damage the wheel cylinder boot.
4. Remove the parking brake rear cable from the operating lever. CAUTION:
Do not bend the parking brake cable.
5. Disassemble the shoe assembly (shoe, springs, adjuster, adjuster lever).
6. Remove retainer ring (A) with a tool to separate operating lever (C) from brake shoe.
• Retainer ring (A)
• Contact point (B)
• Operating lever (C)
• Pin (D)

5. Connect the parking brake rear cable to the operating lever.
6. Install the shoe assembly. After assembly, be sure that each part is installed properly. CAUTION:
Do not damage the wheel cylinder piston boot.
7. Install the brake drum.
8. Depress brake pedal for several times (approximately 2 or 3 times).
9. Adjust clearance of brake shoe. Refer to PB-5, " On-Vehicle Service " .
10. Install rear wheel and tire. Refer to WT-7, " Rotation " .
Removal and Installati on of Wheel Cylinder INFOID:0000000004305917
REMOVAL 1. Drain the brake fluid. Refer to BR-9, " Drain and Refill " .
2. Remove the rear brake shoe assembly. Refer to BR-34, " Removal and Installation of Drum Brake Assem-
bly " .
3. Remove the bleed valve.
4. Disconnect the brake tube from the wheel cylinder.
5. Remove the wheel cylinder bolts and then remo ve the wheel cylinder from the back plate.
INSTALLATION Installation is in the reverse order of removal.
• Tighten bolts and bleed valve to the specified torque. Refer to BR-33, " Component " .
• Refill with new brake fluid and bleed the air. Refer to BR-9, " Bleeding Brake System " .
Disassembly and Assemb ly of Wheel Cylinder INFOID:0000000004305918
DISASSEMBLY 1. Remove boots at the right and left of the wheel cylinder, and pull the pistons and spring out of the cylinder.
2. Remove the piston cups from the pistons.
INSPECTION AFTER DISASSEMBLY Check the pistons, spring and inner wall of the cylinder for wear, corrosion, and damage. Replace any parts as
necessary.
ASSEMBLY CAUTION:
When inserting the piston, be caref ul not to scratch the cylinder.
1. Apply brake fluid to the piston sliding surface on the wheel cylinder.
2. Apply rubber grease to the piston cups and boots and assemble the wheel cylinder as shown.
