These brand-new, genuine Girling slave cylinders were original equipment on many formula cars and sports racers equipped with Hewland transaxles from the 1960s to the 1980s. We offer two styles in two different bore sizes. Both designs are for bolt-on installations. Note that the left-hand and right-hand versions are not mirror images (see photo).
The .75" bore size, which is not very common, is available in a Right-Hand version only (see photo). This unit was original equipment on the Ford Escort "Mexico".
The more common .87" bore is available in either a right- or left-hand version:
The .87" Left-Hand version is ideal for mounting on the right side of the transaxle in most mid-engined cars. This version fits Hewland FG 400, FGA, and FGB gearboxes.
The .87" Right-Hand version is typically installed on the left side of the transaxle in most mid-engined cars. It is most commonly used on the Hewland Mk series, DG 300, and FT 200 gearboxes. Note that on the Mk series, the pushrod points down and both ports are at the top.
For front-engine applications, choose the style which allows the most direct inlet hose routing. The inlet and bleeder ports are interchangeable, so the inlet hose can be installed in either port.
All versions have two 5/16" (8mm) mounting bolt holes oriented perpendicular to the bore and spaced 2 3/8" center-to-center. Overall length approximately 3 1/2" including boot. Inlet and bleeder ports are both threaded 3/8-24 UNF (3AN) with a concave seat. This allows the bleeder to be used in whichever port allows the most direct hose routing. Both bore sizes have a 1.25" stroke. The EPDM seals are formulated to work with any DOT-rated brake fluid (not for use with hydraulic oil). Pushrod not included.
