Classic Performance Residual Check Valves
Classic Performance residual check valves are required in a brake set-up that uses an adjustable proportioning valve. A check valve is run inline on the rear brakes in disc/drum systems to ensure the shoes stay in contact with the drums. Failure to use a residual check valve will allow the brake springs in a drum system to compress the wheel cylinders, resulting in excessive pedal travel. These fittings are available in a variety of sizes, PSI pressure ratings, and finishes.

Classic Performance MCPV-1 Master Cylinders
After years of developing unique brake products, Classic Performance has developed their most innovative product yet. These MCPV-1 master cylinders which combine the master cylinder, double adjustable proportioning valve, removable metering valve and stop light control all in one compact light weight unit, available for Disc/Drum or Disc/Disc applications. The MCPV-1 solves many problems associated with trying to do the same thing with four or five separate pieces being plumed together. Their unique shape allows them be located on the firewall, under dash or on the frame just about anywhere. They are approximately the same size as the ever-popular Corvette master cylinder...only 260 percent lighter. The MCPV-1 has two circuits...front and rear. The front circuit of the MCPV-1 contains the metering valve, which is required on cars that have disc brakes on the front wheels and drum brakes on the rear wheels. The metering valve does not allow any pressure to the disc brakes until a threshold pressure has been reached. The threshold pressure is low compared to the maximum pressure in the braking system, so the drum brakes just barely engage before the disc brakes kick in. Having the rear brakes engage before the front brakes provides a lot more stability during braking. Applying the rear brakes first helps keep the car in a straight line. The rear circuit of the MCPV-1 contains the adjustable proportioning valve and the maximum rear pressure adjustment. The adjustable proportioning valve controls the balance of pressure between the front and rear brakes. For example, if the adjustable proportioning valve was set to 70 percent and the brake pressure was 1000psi, the front brake would get 1000psi and the rear brakes would get 700psi, regardless of what type of brakes a car has. The Maximum Rear Pressure Adjustment controls the maximum rear pressure allowed to the rear brakes to help prevent rear wheel lock up. If the Max Rear Pressure Adjustment is set to 500psi and the adjustable valve set at 70 percent, the front brakes get 30 percent more until the rear reaches 500psi.

OER Authorized Master Cylinder Pushrods
OER Authorized offers master cylinder pushrods for various GM-style master cylinders. Pushrods are crucial for ensuring proper brake pedal height and travel, preventing issues like excessive pedal travel or the inability to fully return the master cylinder piston. If the pushrod is too short, the pedal may require excessive travel to engage the brakes or if the pushrod is too long, it can prevent the master cylinder piston from fully returning, potentially causing dragging brakes or other issues. These pedal rod extensions will allow for easy adjustment to the correct length for the specific application, allowing fine-tuning the connection between both the pedal and master cylinder, ensuring optimal brake performance and feel.

Wilwood Master Cylinders and Tandem Mount Balance Bar Kits
For the ultimate control on the street or track, dual master cylinders with an adjustable balance bar allow brake bias to be fine-tuned to conditions and driver preference. Wilwood provides you with the ability to have that ultimate control with their master cylinders and tandem mount balance bar kits. The kits feature a tandem mount balance bar assembly offered with or without eyelet and paired with either two high-volume, aluminum master cylinders or two compact, remote flange master cylinders for those with limited space applications but requiring the output capacity of a full-size master cylinder. The tandem mount balance bar assembly (with or without eyelet) give modified street cars and trucks the precision-control usually reserved for race vehicles. Each one is a lightweight, forged billet aluminum assembly that bolts to the firewall, replacing the tandem master cylinder with a balance bar and sturdy dual master cylinder mounts for two race-type vertical bolt pattern master cylinders, with no custom fabrication needed. You can easily adjust brake bias with the included knob and the bar assembly is designed with oval mounting holes for 3.22 in. to 3.40 in. on-center studs for a wide variety of vehicle fitments. Wilwood's high-volume aluminum master cylinders feature high-pressure, diecast bodies with the highest fluid capacity of any integral reservoir design. With a total capacity of 8.2 oz., there is at least 26 percent more fluid volume than other brands, and more fluid volume means cooler temperatures and additional insurance for extreme conditions where high pad wear can compromise fluid levels during long events. The 1 7/16 in. piston travel offers plenty of margin when used with large 4- or 6-piston calipers and the heavy-duty internal springs provide fast retraction. Formed steel lids with bellows-type gaskets keep the moisture out. Wilwood's compact remote flange master cylinders have ultra-short 3.37 in. black e-coated aluminum bodies to provide 2.16 in. of additional clearance between the mounting flange and the fluid outlet. A full 1.12 in. of piston stroke meets or exceeds the stroke capacity of most full size cylinders, and with a 1/8 in. NPT fluid outlet port located at the top radius of the cylinder bore, the chance for trapped air is reduced. An enhanced fluid inlet port allows mounting of the standard reservoir included and also contains 11/16 in.-20 internal threads for custom reservoir arrangements.
