Dorman - First Stop Clutch Master Cylinder P/N:CM640099
$103.99
Clutch pedal gone soft or leaking fluid? The Dorman - First Stop Clutch Master Cylinder CM640099 generates the hydraulic pressure that disengages the clutch when you press the pedal, sending fluid on to the slave cylinder. It's a direct-fit replacement for the 2003-2007 Saturn Ion (L4-2.2L), 2004-2007 Saturn Ion (L4-2.0L), and 2006-2007 Saturn Ion (L4-2.4L). Reverse-engineered from the original equipment, it's built to match the factory clutch master cylinder's design and function on these applications.
- Aluminum body: a standard-replacement clutch master finished in silver/black.
- 5/8 in bore: external-type cylinder sized to the original.
- High-grade rubber components: compatible with standard brake fluid.
- No reservoir; not pre-bled/pre-filled: a reservoir is not included, and the unit ships un-bled, so bleed the clutch hydraulic system after installation.
If a leaking or worn clutch master cylinder is the cause of a soft pedal or difficulty shifting, this replaces it; diagnose the cause first, as these symptoms can have other sources. Backed by a U.S.-based team of engineers and quality-control experts. Country of origin: China.
