Disassembly and Assembly of Brake Caliper AssemblyINFOID:0000000005928414
DISASSEMBLY
1. Remove the caliper assembly. Refer to BR-30, "Removal and Installation of Brake Caliper Assembly".
2. Remove sliding pin bolts and remove cylinder body from the torque member. Remove pads, shims, pad return spring
(AD22VK) and pad retainers from torque member as necessary.
CAUTION:
When removing pad retainer from torque member, lift the
pad retainer in the direction shown by arrow, so as not to
deform it.

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, w ear, 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. R eplace 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.
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cr acks, and serious damage. Replace as necessary.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub at two 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 - 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 specification, 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.
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. Install pads, shims, pad return spring (AD22VK) and pad retainers on the torque member. Refer to BR-26,
"Removal and Installation of Brake Pad".
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-30, "
Removal and Installation of Brake Caliper Assembly".
Standard thickness (new) : Refer to
BR-42, "
Front
Disc Brake".
Repair limit thickness : Refer to BR-42, "
Front

Brake Burnishing Procedure
INFOID:0000000005928415
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 vehicle 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.
