Wilwood has introduced the first series of rear disc brake conversion kits using their new  Combination  Parking  Brake  Caliper.  The  calipers  use  hydraulic  pressure  for stopping and an internal mechanical lock for the parking brake. CPB kits provide matching style and performance for Wilwood’s already extensive line of front Big Brake upgrades. A choice of 11.00” or 12.19” diameter discs is available for most 4 lug Civics and Integra’s from 1984 to 2010.
