The Tandem Aluminum Master Cylinder from Wilwood is available in bore sizes of 1.00" and 1-1/8"; and finishes including plain, ball burnished, and black e-coat.
Designed primarily for manual applications, the 7/8" bore master cylinders include a pushrod.
The 1" bore can be utilized in both manual and power-assisted applications and does not include a pushrod.
Primarily designed for power brake applications, the 1-1/8" bore works with either vacuum assist or hydraulic assist systems.
Designed for mount flanges ranging from 3.22" to 3.40", these measurements are common for most domestic cars and trucks from the mid 1960s to present, and they feature 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.
Each master cylinder, machined from high-pressure die castings, weighs only 3lbs, achieving a 75% weight savings over most cast iron OE type master cylinders.
A combination proportioning valve kit is also available, which includes brackets and stainless lines specifically for use with these master cylinders, see PN 260-13190, or 220-13189 for the retrofit kit.
