    Wilwood's Drilled Steel brake rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. Steel rotors are typically found in lighter weight open wheel cars such as sprints and modifieds. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

    AFCO 3/4" master cylinder rebuild kit for AFCO master cylinders manufactured after January 2013

    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.
