AFCO 7/8" master cylinder rebuild kit
Racer Note: Master cylinder bores are built with close tolerances. Stroking the master cylinder dry can cause damage to the internal rubber seals causing leaks, soft pedal, and lack of pressure. Never clean a master cylinder with carburetor cleaner or similar products as they will cause seal damage.
Racer Note: When rebuilding brake master cylinders and calipers, always lubricate internal parts with brake assembly fluid before installation.
This will keep seals and o-rings from becoming damaged by dry cylinder walls and pistons.
