Dorman CM116209 Clutch Master Cylinder Compatible with Select Chevrolet / GMC Models

I’ve had many 88-93 Chevy trucks. All manual transmission. Most with this set up. Replacing the stock cast iron master/slave cylinders with aluminum and plastic never lasts. I’ve rebuilt several stock cast iron units and worked great. I was so glad to see a nice new cast iron piece in the box. They are better and no flex or heat issues. I have a high performance clutch that’s bigger than stock and it works great. Easy to bleed. Pedal feel is perfect. Great part and i am pleased with it.

The body of this was thicker metal than the previous replacement - Good quality and value. This fit perfectly on my 1988 K1500 Scottsdale# 5.7 liter, standard cab, full size bed, 4x4. I bench bled this unit, on the recommendation of a parts store guy, when buying a bleeding kit and the hose assembly that goes between this and the slave cylinder. I highly recommend bench bleeding, especially if doing this on your own. Also recommended buying the hose assembly and bleeding kit at the same time...you'll need it. The old hose/tube ends were seized at both ends and I had to twist them off, to remove the master and slave assemblies. I am glad that I didn't buy the pre-bled master/slave set that comes with assembled with the hose assembly, because unless you drop the clutch and/or engine assembly, I don't think you could get the hose routed without taking them apart.

I was serching for the original one but I could not find it , so bought it 3 month ago its doing the job with no issue

Fit perfect.I would buy it again.

Not as well built-as the original...

I’m ordering a second to give it another try. Hoping I just got the bad one. But this one is defective, won’t pump up.

The product is slightly different then the original this makes not fit.

a plus
