Cylinder Body
Check inside surface of cylinder body for score, rust wear, damage or foreign materials. If any of the above
conditions are observed, replace cylinder body.
Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine emery paper.
Replace cylinder body if necessary.
CAUTION:
• Use new brake fluid to clean. Do not use mi neral oils such as gasoline or kerosene.
Torque Member
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston
Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the above con-
ditions are observed.
CAUTION:
• Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
Sliding Pin Bolts and Sliding Pin Boots
Make sure there is no wear, damage, or cracks in sliding sleeve and sliding sleeve boots, and if there are,
replace them.
ASSEMBLY
1. Install the bleed valve and cap.
2. Apply rubber grease to the new piston seal (1) and insert the new piston seal (1) into the groove on the cylinder body.
CAUTION:
Do not reuse piston seal.
3. Apply rubber grease to the new piston boot (1). Cover the piston end (2) with the piston boot (1), and then install the cylinder side
lip on the piston boot (1) securely into the groove on the cylinder
body.
CAUTION:
