A very compact unit, at a good price value. Finished in a dull raw finish that's easily painted if needed. Looks great as it comes also. About 1.25" stroke.

Rebuild kit 8352606 includes the pushrod that you need but the other items of that kit are not correct for this master cylinder. Sorry we do not have a rebuild kit made for this master cylinder.

The best way to bleed your throwout bearing is to have someone open the bleeder then push the pedal all the way down and hold while they close the bleeder. Once the bleeder is closed release the pedal. Repeat the process until you no longer get any air out of the bleeder.

I bought this MC under the assumption that it was 1/8" NPT. It is not. What's tapped into the MC appears to be some sort of flare fitting, 3/8-24 threads.

This Master Cylinder will use a 5/16”, right hand thread heim. I suggest something like our 175-0202. This will use a 5/16” cross-bolt as well (to secure the heim to your pedal).

This master cylinder has a vertical mount pattern of 2 ¼” center to center as compared to the horizontal mount pattern for most GM applications. We offer a master cylinder adapter kit under part number 8352503677 that includes the vertical to horizontal mount adapter plate, a clevis for the pushrod and a different length push rod if needed along with some hardware and a rubber push rod boot.
