Wilwood 260-7563 Details

Tandem remote master cylinders provide one of the safest ways to actuate four wheel or dual caliper axle brake systems. This versatile, lightweight and easily adapted master cylinder provides single pushrod activation of two separate brake fluid circuits. By completely isolating the fluid reservoirs and circuits, the front and rear brakes are able to operate independently of each other and provide a safety net should any one side of the system become inoperable. Shipped complete with the master cylinder and all necessary hardware including 30 inches of hose that can be cut to the desired length for remote mounting of the two 4 ounce fluid reservoirs. 

  • Can be bolted directly to Wilwood single mount pedals
  • 50/50 front/rear brake output from a 1.00" bore with 1.10" stroke
  • Great match for Wilwood's Bolt-On-Disc Brake Kit systems configured from OE components
  • Reservoirs can be either remote or master cylinder mounted

Overall Assessment

Customers found the product to be a quality upgrade for older brake systems, able to easily fit into small spaces and models like 1946 Willys cj2a and 1931 Model Lay. It features a readily adjustable part and comes with 10lb residual valves. User-friendly installation processes, along with its cost-effective pricing, were well-received attributes. It's particularly appreciated for its added safety feature of separating front and rear brake systems, which helps prevent accidents due to catastrophic brake failure. Some customers did wish for included bleeders plugs. This product far outscores competitors in terms of quality, practicality, and safety.

I used this item to upgrade the brakes on a 1946 Willys cj2a. The installation was really simple. I mounted the master cylinder to a 3" x 4" x1/4" thick plate. The plate was then welded to the mount on the frame where the old master had been. I used the support that connected the brake pedal pivot to the old master cylinder by simply shortening it up and bending it 90° then bolting it to the new mount. The remote reservoirs were mounted on the firewall above the master cylinder. This unit came with 10lb residual valves for both front and rear brakes. They are simple to remove before the brake lines are hooked up. My Jeep has discs in front and drums in the rear so I took both residual valves out because I already had a 10lb residual valve in the rear brake line, I installed a 2lb residual valve in the front brake line. The original Jeep pushrod works fine by simply grinding the knob off of the end, it is also adjustable.

Crashed when we lost brakes in the race car using a single reservoir master cylinder . This is a good product separating front and rear brake systems to help allow the car to stop if there is a catastrophic failure in the brake system. I needed a firewall adapter to make it fit to the Toyota MR2, but this was easy to make with plate aluminum/steel.

Very basic, effective, inexpensive, and easy to install. Wish plugs for the bleeders were included.

Do the remote reservoirs have to be above the master cylinder? If so will you give me a part# for a master cylinder that has a 1" bore that is shorter than 4.460 tall and will fit your swing pedal?

Is there a way to use this cylinder with a 340-1289 floor mount pedal? It would appear that the lines exit the bottom of the cylinder.
