Description

Clutch Slave Cylinder Bleed Screw for the hydraulic clutch release circuit. It threads into the clutch slave cylinder, at the highest point of the fluid chamber.

Opening the screw releases trapped air from the slave cylinder when bleeding the system, restoring a firm pedal and full clutch release; closed, it seals the hydraulic circuit against fluid loss. A seized or rounded bleed screw is a common reason a slave cylinder cannot be bled and is renewed in its place.
