Piston Boot / Piston Removal
Protect caliper body with cloth. Blow compressed air through brake hose to remove piston boot and piston.
Caution: Blow compressed air gently.
Insert a piece of wooden plate as shown and blow compressed air through the brake hose connecting hole to remove the pistons. Adjust the compressed air pressure as necessary so that both pistons are forced out evenly.
Caution:
1. Be careful not to pinch your fingers.
2. Be careful not to splash the brake fluid.
Piston Seal Removal
1) Remove piston seal with finger tip.
Caution: Do not damage the cylinder inner surface.
2) Clean piston surface and inner cylinder with trichloroethylene, alcohol or specified brake fluid.
Specified brake fluid: Conforming to DOT3 or DOT4
INSPECTION
- Check cylinder for wear, damage or rust.
- Check piston surface for wear, damage or rust.
- Check caliper body or sleeve for wear.
- Check pad for damage or adhesion of grease and check backing metal for damage.
- Check wear indicator for damage.
Pad Wear Check
Measure the thickness at the thinnest worn area of the pad. Replace pad assembly when pad thickness is less than the limit value.
Standard value: 10.0 mm (0.39 inch)
Limit: 2.0 mm (0.08 inch)
Caution:
1. When the limit is exceeded, the brake pads on both the left and right wheels must be replaced as a set.
2. If there is a large difference in thickness between the pads on the right and left wheels, check the sliding portions of the caliper.
