Get hydraulic clutch actuation working again with the Dorman - First Stop Clutch Master Cylinder CM640063. It installs as a direct replacement for the 2004-2006 Scion xA [L4-1.5L], 2004-2006 Scion xB [L4-1.5L], and 2000-2005 Toyota Echo [L4-1.5L]. The clutch master cylinder converts clutch-pedal force into hydraulic pressure that travels to the slave cylinder to disengage the clutch during shifting.

Because those symptoms can have other causes, diagnose the source first; if a failed master cylinder is the cause, this direct replacement addresses it. Country of origin: Taiwan.
