Wilwood Announces New 15/16-inch Bore Tandem Master Cylinder

Tandem MC Collage-2Whenever an enthusiast is upgrading and enhancing a vehicle’s performance, it’s always a good idea to look at the braking system – after all, what good is the “go” if there’s no “whoa” to keep you out of the trunk of the driver ahead of you? Wilwood Disc Brakes has the solution in the form of their new 15/16-inch bore master cylinder, designed to match up with caliper upgrades to provide the proper amount of fluid processing power.

Official Release:

Wilwood’s 15/16” bore tandem master cylinder provides a new option for matching cylinder output to caliper capacity with custom brake upgrades on single pushrod, manual pedal brake systems.

The high-capacity body is lightweight, adds high-tech style, and has the durability for street or track. The machined billet lid captures a pressure balancing bellows gasket that fully seals moisture out and fluid in.

Standard finishes include bright media burnished for a polished look, glossy black e-coat, or plain as-cast aluminum. The master cylinders are available as stand-alone units, or can be purchased in a kit. Tandem master cylinder kits include master cylinder, combination proportioning valve, mounting bracket, pre-bent fluid tubes, and mounting hardware.


  • Available in a variety of finishes – polished, gloss black, or as-cast
  • Designed to match master cylinder to caliper capacity on brake upgrades
  • Made in the USA
