I have a Hydroboost unit I had on my 95 RRC. Worked great, the master cylinder was bought new and has about 1000 miles. Included is the boost pump, master cylinder, hydraulic lines that will fit all RRC and DI's, brake line fittings for master cylinder and a reservoir. You may need to get a new rod for the rear as I had to cut, measure and weld the end piece on. If you are not familiar with the hydroboost, do a search in the Discovery tech for hydroboost or hydraboost. Asking 165 shipped OBO
