Wilwood’s Tandem Aluminum Master Cylinder is available in 2 bore sizes 1.00†and 1-1/8â€; 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 3.40â€, 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.

Generally happy
Style: Tech Pack 28 sqft, Style: Tech Pack 28 sqft
Much thinner than I expected, but installation went better than I'd thought it would. Needed to line the interior of the engine cover of a Ford E450 RV. Tried nitrile gloves, but they stuck to the material so did it bare handed. Cut easily with a fresh razor blade. Pressed in place with a plastic putty knife. We'll see the effectiveness on the next trip.
