Buy the master cylinder that matches whichever booster you bought. In my case, I bought the booster for the S10 so i also got the MC for the S10.[This message has been edited by PaulJK (edited 06-01-2014).]

No
Would you really want a threaded rod over a solid one? These are your brakes we are talking about here.

Yes, I am, you can get one here http://www.fiero.nl/forum/Forum4/HTML/060500.html

The booster works with ALL other brake upgrades and setups

The GA swap will help get rid of brake fade, has the same size rotors(but vented), a little bigger piston. Not that noticable braking wise, but the lack of fade is.

By the way, you should try to "panic stop" after you install the bigger booster. When i tried mine, i got resistance from the brake pedal - it would not press down for about a second. I was not comfortable with this, so i upgraded to the bigger master cylinder and it solved the problem.

You had other problems, the booster did NOT cause that. Prob a bad master in the first place.

That is not the right way to do it, you ONLY want to go with a bigger master IF you have bigger calipers and they need more fluid to move. See the Orge's cave.
A bigger master will decrease the pressure to the calipers. Again see the Orge's cave.

Wow, sounds like you know a lot more than everybody including my car and you never even saw it (the master cylinder i took off was less than a year old & i made no other changes, ONLY changing the MCs) !
I posted what WORKED for me.[This message has been edited by PaulJK (edited 06-01-2014).]

The master size is one of the great debates on this thread right here. See early pages.

Amazing. I left the house at 1:30, went to the U-pull yard, got a like new Booster from a '96 S10 ($20), came home, & installed it. (It is now 7:30) So, How easy was that ?!. The difference is "Night and Day". I needed 2 feet to stop it before, now I have to be care full I don't throw my self through the windshield !
I Highly recommend this upgrade. ( now I'll have to go get another booster for my other fiero) Thanks to all you guys for documenting the swap !

Comparing dead booster, likely other brake parts bad too, to good booster is proof to what exactly?
"I needed 2 feet to stop it" is High Effort problem and often a sign Booster is bad and/or vac line to it have issues. Can be iffy pads, iffy/bad MC, or bad calipers too.
"now I have to be care full I don't throw my self through the windshield !" Some like this. Many will hate it. Over boosting is a problem to many. Over boost can made brakes that are very hard modulate when stopping in rain, on snow dirt etc.

I hear exactly what you are saying. but....
I had good stock brakes before the booster upgrade (I went through everything, SS lines, different ,stock, boosters, calipers don't stick slide nice, ebrake adjusts on first swing, new MC) and it just didn't seem right, good high firm pedal, but when I needed to stop NOW I had to stand on it, otherwise daily driving, they worked fine, everyone who drove my car (other Fiero owners) said I had great brakes. (BTW the biggest improvement was getting the E-brake to adjust, IIRC I had to replace a caliper) I was happy after that and all was fine but the more I drove newer cars the more I keep thinking something was wrong with the Fiero. I had allready swaped to drilled and slotted rotors, that got rid of ALL the brake fade, I swaped on the GA swap up front (as it was on another Fiero in the yard so cost was zero)
Not untill I swapped to the bigger booster was I really satified with the Fiero brakes.
When people buy/ask about a booster, I usally tell them to adjust the e-brake and make sure the system is in working order before hand. I agree with you I don't want the booster being a band aid/masking other problems. But the bigger booster is REAL NICE, you get used to it and can modulate the brakes just fine. What is scarry is haveing good stock brakes, standing on it as the dumb@#$ in front of you doesn't have brake lights and you notice late and worry if you can stop in time.
And, ok I will put this in caps, IF YOU CAN LOCK UP YOUR TIRES, YOU NEED BETTER TIRES, PERIOD!!!
Now look at where the booster comes from, an S10, Do you know the S10 comes with 3 different size boosters.?. Same vehicle, but the duke S10 only has a single diaphram booster, the 2.8L S10 has a Fiero size dual diaphram booster, the 4.3 S10 has the dual diaphram, bigger size booster. SAME CAR/TRUCK now if overboosting is a problem why does it not show up on the S10s.?. I have seen NOT ONE, not even one, person who did the upgrade, say "this sucks" not one.

So are Grand Am calipers considered "bigger calipers"? Dont they have a larger piston? If so, would they benefit from a larger MC and if so, which one is recommended?
Btw, thanks for answering my questions, I'll PM you in the next few weeks once I pull the first engine out

Ogre, All new premium pads, all new rotors, calipers, hoses, no air in lines. Old Booster did not have a" vacuum leak", still held vacuum from at least DAYS before I disconnected it. no leak from engine to booster. All was new BEFORE putting the 96 S10 unit on. Is it possible the old booster Was bad without showing any "Signs" of it ?

They are only a little bit bigger, if you only do one set IE the fronts, the bigger MC is a bit bigger than needed for both front and back, so adding a bigger MC with just one set is is too much and will decreae pressure to the calipers, it was in the Orgre's cave all the specs, I am having a hard time finding the page. beyond that I don't have a broad enough knowledge base of MCs to recommend one.

Yes it is, I have tested a booster that held Vac just fine but did not provide brake assist. Just FYI
