1964-72 A-Body, 1967-69 F-Body, 1968-74 X-Body Show Stopper HydraStop complete hydraulic assist brake kit
The CPP Show Stopper HydraStop Kit is engineered for 1964-72 A Body, 1967-69 F Body, and 1968-74 X Body GM platforms and delivers a premium hydraulic assist upgrade for classic muscle car builds. These vehicles are frequently equipped with upgraded suspension, disc brake conversions, and performance engines that can limit available vacuum assist. HydraStop eliminates that issue by using steering system pressure to generate up to 1800 psi at the wheels for responsive and predictable braking performance. This Show Stopper configuration features a billet aluminum firewall mount bracket, stainless high pressure hoses with return lines, AN6 fittings installed, master cylinder, and chrome accumulator cover for enhanced engine bay presentation. Designed specifically for GM performance platforms seeking both braking authority and refined appearance. HydraStop systems are new production assemblies supported by a limited lifetime warranty when installed with a power steering filter.
