Wilwood rear Disc/Drum bracket kits (sold less caliper brackets) are machined from high-strength aluminum alloy and use steel 5/16-24 clinch nuts for mounting. The kit comes fully populated with drum parking brake shoes, springs and adjusters and accepts caliper or accessory mounting. To use with 12.88"–14.00" hat-mount rotors, additional caliper brackets are required for a complete installation.
