DISASSEMBLY SERVICE POINTS
PISTON BOOT/PISTON REMOVAL
CAUTION Blow air gradually to remove the pistons. The pistons will rush out if a force of air is applied suddenly.
Cover the caliper body outer side with a cloth or similar materials.
Blow compressed air through the brake hose installation area to remove the piston and piston boot.
PISTON SEAL REMOVAL
CAUTION Do not use a flat-tipped screwdriver to remove the piston seal. This may damage the inner side of the cylinder.
1. Remove the piston seal with your finger tip.
2. Clean the piston surface and cylinder inner face with alcohol or specified brake fluid.
Brake fluid: DOT3 or DOT4
INSPECTION
- Check the cylinder for wear, damage or rust.
- Check the piston surface for wear, damage or rust.
- Check the caliper body for wear.
- Check the pad for damage or adhesion of grease, check the backing metal for damage.
BRAKE PAD WEAR CHECK
WARNING
- Always replace both brake pads on each wheel as a set (both front wheels or both rear wheels). Failure to do so will result in uneven braking, which may cause unreliable brake operation.
- If there is significant difference in the thickness of the pads on the left and right sides, check the moving parts.
Measure thickness at the thinnest, most worn area of the pad.
Replace the pad assembly if pad thickness is less than the limit value.
Standard value: 10.0 mm (0.39 inch)
Limit: 2.0 mm (0.08 inch)
