Press the clutch pedal and the Dorman First Stop Clutch Master Cylinder CM39750 turns that pedal effort into the hydraulic pressure that pushes fluid to the slave cylinder and disengages the clutch. It drops in as a direct-fit replacement for the 1983-1985 Toyota Corolla [L4-1.6L], 1984-1985 Toyota Corolla [L4-1.8L], 1986-1989 Toyota Celica [L4-2.0L], and 1986 Toyota Celica [L6-2.8L].

  • Direct replacement: reverse-engineered from the original equipment so it installs and operates like the clutch master it replaces on the listed vehicles.
  • Durable materials: includes high-grade rubber components compatible with standard brake fluid.
  • 0.625 in bore: built to the original inside-diameter specification for the listed applications.
  • Trustworthy value: backed by a team of engineers and quality-control experts in the United States.

Signs this part may need replacing include fluid seeping from the cylinder, a soft or spongy clutch pedal, or a pedal that sinks toward the floor and makes shifting hard. If a failed clutch master cylinder is the cause, this replaces it — diagnose the hydraulic clutch system first, since those symptoms can have other causes. Item grade: Standard Replacement. Country of origin: Taiwan. Manufacturer part number CM39750.

What are signs my clutch master cylinder may be failing?
