INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mi neral oils such as gasoline or kerosene.
 Check the inner wall of cylinder for corrosion, wear, and damage. If a malfunction is detected, replace cylin-
der body.
 Minor flaws caused by corrosion or a foreign material can be removed by polishing a surface of the inner wall with a fine sandpaper. Replace cylinder body, if necessary.
Torque Member
Check for wear, cracks, and damage. If a malfunc tion is detected, replace the torque member.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.
Check piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable part.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. If a malfunction is
detected, replace applicable part.

2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that wheel bearing axle end
play is within the sp ecification. Refer to FA X - 4 , "
On-Vehicle
Inspection" (2WD models), FA X - 11 , "On-Vehicle Inspection"
(AWD models).
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 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:0000000001327632
Burnish brake pad contact surfaces of disc rotor according to following procedure after refinishing or replacing
drums or rotors, after replacing pads or linings, 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. Measurement point
