Description
Master Cylinder - Tandem - 1.125 in Bore - 1.100 in Stroke - Integral Reservoir - Aluminum - Burnished - Kit
Wilwood High Volume Tandem Master Cylinder - 1 1/8in Bore Ball Burnished
Wilwood’s Tandem Aluminum Master Cylinder is available in 2 bore sizes 1.00” and 1-1/8”; and 3 finishes, plain, ball burnished and black e-coat. 7/8” bore master cylinders are designed primarily for manual applications and include a pushrod. The 1” bore can be used in manual and power assisted applications and does not come with a pushrod. The 1-1/8” bore is designed for use primarily with power brake applications, either from vacuum assist or hydraulic assist systems. They’re designed for mount flanges from 3.22” to 3.40”, common measurements for most domestic cars and trucks from the mid 1960s to present, and offer fluid outlet ports on both sides of the bore. The stroke is set at 1.10” with a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3lbs, a 75% weight savings over most cast iron OE type master cylinders. We also offer a our combination proportioning valve kit, which includes brackets and stainless lines specifically for use with these master cylinders, see PN 260-13190, or 220-13189 for retrofit kit.

Wilwood tandem chamber master cylinders represent the latest refinements in brake pressure actuation and fluid control. They are available in plain, ball burnished, and black e-coat finishes. The features incorporated into the innovative and unique design make them the perfect choice for a wide range of custom manual or power brake applications. High-pressure diecasting of a premium alloy produces a high-capacity body that is lightweight, looks great, and has the durability for competition. A machined billet lid captures a pressure-balanced bellows gasket with 100 percent sealing against moisture invasion or fluid leakage.
