genuine AP from the original tooling. The Mini Pre Verto 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. Repair kit is
GRK4008.
Bolt to hold slave cylinder is
GFK5240.
