CPP HydraStop Kits are high-performance hydraulic assist brake systems designed to upgrade manual or vacuum-assisted brakes to modern, compact hydraulic units. These systems work off your power steering pump. These direct bolt-in kits include a high-performance hydraulic brake assist unit, billet aluminum firewall mounting bracket, braided stainless high-pressure lines, a heavy-duty power steering return line, and all necessary hardware. Delivering up to 1800 psi at the wheels, these systems ensure exceptional braking performance and ease of installation using standard tools.

The "Show Stopper" package features a chrome master cylinder, chrome adjustable proportioning valve, distribution block, chrome accumulator cover, and stainless pressure hoses, paired with a billet aluminum firewall bracket. This kit works with the original brake pedal for a seamless upgrade.
