Changing one of the clutch hydraulic cylinders requires you to bleed the system in order to get things back into working order. You can't have air bubbles in the system and bleeding the system by yourself can be a royal pain! Replace the bleeder valve on the slave cylinder with a SpeedBleeder and complete the job in no time! The spring-loaded ball bearing in these valves lets you pump the clutch pedal without having to manually open and close the valve with each pump, and prevents air from being pulled back into the system.
NOTE: This is a SINGLE SpeedBleeder specifically for the 3000GT/Stealth clutch slave cylinder.
