3. Coat caliper mounting bolts with silicone grease. Then install and tighten bolts to 15 Nm (11 ft. lbs.).

Mounting Bolt Dimensions:

CAUTION: If new caliper bolts are being installed, or if the original reason for repair was a drag/pull condition, check caliper bolt length before proceeding. Bolts must not have a shank length greater than 67.6 mm (2.66 in.).

CORRECT SHANK LENGTH:

4. Install brake hose to caliper with new seal washers and tighten fitting bolt to 31 Nm (23 ft. lbs.).

CAUTION: Verify brake hose is not twisted or kinked before tightening fitting bolt.

5. Bleed base brake system.

CLEANING
Clean the caliper components with clean brake fluid or brake clean only. Wipe the caliper and piston dry with lint free towels or use low pressure compressed air.

CAUTION: Do not use gasoline, kerosene, paint thinner, or similar solvents. These products may leave a residue that could damage the piston and seal.

INSPECTION
The piston is made from a phenolic resin (plastic material) and should be smooth and clean.
The piston must be replaced if cracked or scored. Do not attempt to restore a scored piston surface by sanding or polishing.
