5. Using a flat-bladed screwdriver, remove piston seals from cylin- der body.
CAUTION:
Be careful not to damage cylinder inner wall.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
 Use new brake fluid to clean. Do not use mine ral oils such as gasoline or kerosene.
 Check inside surface of cylinder for score, rust wear , damage or foreign materials. If any of the
above conditions are obser ved, replace cylinder body.
 Minor damage from rust or foreign materials m ay be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.
Torque Member
Check for wear, cracks, and damage. If damage or def ormation is present, replace the torque member.
Piston
CAUTION:
 Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
 Check piston for score, rust, wear , damage or presence of foreign materials. Replace if any of the
above condition are observed.
Sliding Pin Bolts and Sliding Pin Boots
Check sliding pin bolts and sliding pin boots, for wear, damage and cracks. If damage or deformation is
present, replace the applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boots. Cover the piston end with piston boot, and install cylinder side lip on piston boots properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.

3. Apply brake fluid to piston, and press piston into cylinder bodyby hand to assemble piston side lip on piston boot properly into
groove on piston.
CAUTION:
Press piston evenly and change the pressing point to pre-
vent the inner wall of cylinder from being rubbed.
4. Fix piston boot with retaining ring. CAUTION:
 Make sure boot is firmly in cylinder body groove.
 Do not reuse retaining ring.
5. Install sliding pin bolts and sliding pin boots to torque member.
6. Apply PBC (Poly Butyl Cuprysil) grease or silicone- based grease to the backside of brake pad and to both
sides of shim, and attach inner shim and shim cover to inner pad, and the outer shim to outer pad.
7. Assembling shims and shim cover to pad. CAUTION:
When attaching pad retainer, inst all it firmly so that it does
not float up higher than torque member, as shown in the fig-
ure.
8. Install brake pad retainer and pad to torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified torque. Refer to BR-24, "
Component".
10. After installing caliper assembly, refill with new brake fluid and bleed air. Refer to BR-8, "
Bleeding Brake System".
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cra cks, and serious damage. If a malfunction is detected,
replace applicable part.
Runout Inspection
1. Using wheel nuts, fix the disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the specification. Refer to RAX-6, "
On-Vehicle
Inspection".
3. If runout is outside the limit, find minimum runout point by shift- ing mounting positions of disc rotor and wheel hub by one hole.

Measurement point : At a point 10 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.05 mm (0.0020 in) or less

4. If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro-Cut PFM On-Car Br ake Lathe (Tool No, 38-PFM90.5) or equivalent.]
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
Brake Burnishing ProcedureINFOID:0000000001327638
Burnish the brake pad or lining contact surfaces of rotor according to following procedure after refinishing or
replacing drums or rotors, after replacing pads or li nings, or if a soft pedal occurs at very low mileage.
CAUTION:
 Be careful of vehicle speed because brake does no t 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 for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Standard thickness : 16.0 mm (0.630 in)
Wear limit : 14.0 mm (0.551 in)
Maximum uneven wear
(measured at 8 positions)
: 0.015 mm (0.0006 in) or
less
