Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Assembly Procedure
- Apply a small amount of clean DOT-3 brake fluid to the piston, piston seal, and piston bore.
- Install the square-cut piston seal in the brake caliper bore groove.
- Ensure that the square-cut piston seal is not twisted.
- Install the boot over the end of the piston so that the fold will face toward the brake caliper housing piston bore opening.
When applying the clean brake fluid to the piston bores, piston seals and pistons, only apply the brake fluid to one bore at a time. This is done to ensure that the brake caliper, seals and pistons DO NOT become contaminated with dirt or other foreign material.
