ok none of my local parts store has a master cylinder in stock . What im wondering is there any vehicles out there that would be compatible with a 88 fiero notch back with the 2.5 engine?
1994 S10 or Blazer, both will be bigger than stock with the blazer being the Biggest. I think the Blazer MC would be too big for stock brakes, I recommend using the Fiero MC, but you could probably get away with the S10 MC.
It is a little bigger than stock (I believe) and bolts right up and threads right up, but it will change your braking a little. You will be able to produce a little less line pressure at the same pedal effort, but pedal travel will be reduced.
I said 1994 because I have a 1994 Blazer MC in my Grand Am brake swap so I am certain that year will work.
I went through several MC's before finding a good one that doesn't leak. Watch out with remans, they may have issues out of the box. Let me see if I can find the thread with more info.
The Blazer MC I bought was 27 dollars NEW from Rock Auto made by Cardone. It is great, no probems. I am sure you can find the S10 one for the same price.
Which master do you have. The one with the line out the end or out the middle? If the line is out the middle you can ask if they have or can get you a rebuild kit. If there is a clutch and brake rebuilder in your area they might carry them. Get a rebuild master kit for an 89 Jeep Cherokee. If the one with the line out he front end no ideas. I've never looked at my 88 to see which it has for sure.
