The Classic Mini clutch slave cylinder is a vital link in the proper operation of the Mini clutch. The master cylinder feeds the slave cylinder to exert the mechanical pressure to dis-engage the clutch. The simple sounding process is only complicated by a worn cylinder. As the wear continues it first will probably bypass, this will mean that the clutch will not stay dis-engaged when holding the pedal down. The next more obvious sign is when you see actual fluid leaking! The slave cylinders are easy to replace! The cylinder bore size is 7/8" diameter. For Pre-Verto style clutches. For Mini Verto clutch cylinder, see part GSY118MS or GSY118 for genuine type.

The same slave cylinder was used in Sprites & Midgets that used combined brake & master cylinders, 948-1098cc from 1958-1966.
