Wilwood’s tandem chamber master cylinders represent the latest refinements in brake pressure actuation and fluid control. The exclusive Wilwood features incorporated in this innovative and unique new design make it the perfect choice for a wide range of custom manual or power brake applications.

Each master cylinder is configured with full separation between the front and rear reservoir chambers and fluid outlets. There is a pressure access on both sides of the piston bore for right or left hand plumbing based on mount location. A total piston stroke of 1.10” is distributed at a 2:1 volume ratio between the primary and secondary chambers.
