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.

  • Direct replacement: built to match the original clutch master cylinder on the listed vehicles.
  • Precise design: reverse-engineered from the original equipment for a reliable fit and function.
  • Specs: 0.625 in bore with an M10 x 1.0 outlet thread.
  • Durable materials: includes high-grade rubber components compatible with standard brake fluid.

Signs the clutch master cylinder may need replacing include fluid seepage at the cylinder, a soft or sinking clutch pedal, or difficulty 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.
