S10 master cylinder swap

[Dinosport]

Bump on this topic. Just wondering if anybody else has swapped to this master with out having started with a bad one and noticed if there was any difference.
I have the s10 for the front plus ls1 rears. Dont know If I should do a master as a part of that swap?

Well I asked a question and got hit with a Disagree? Disagree about what? Was it a stupid question?

That 'disagree' is most likely just an accidental fat-finger on a cell phone.

I was hoping somebody with experience would chime in.

Your probably right. Im hoping somebody that has done this swap before and can give us a real comparison vs the factory one can give there 2cents on if its worth while to do.

The heart of the matter is that a larger bore master cylinder will provide a pedal that takes slightly more effort but requires less travel for the same response. The S10 master cylinder wouldn't benefit me since my car was a diesel and I've decided to retain the hydroboost. The stock master cylinder for my car has a 1-1/16" bore. I looked up master cylinders for a 2000 S10 pickup and for a 2000 Blazer on Rock Auto and they show a 1" bore for those applications. If your stock master cylinder is a 7/8" bore then that S10 master cylinder would be an upgrade for you.

I have the SSBC front brake upgrade kit, and I'm looking at discs off of a firebird/camaro for the rear of my 86 grand prix. Would I be able to bolt this master cylinder and not have to worry about a metering block/proportioning valve?

If you go to rear disc you will need a disc/disc proportioning valve.

Alright, thanks

If you look up the master cylinder for your car on RockAuto it will list the stock bore size.
