Would swapping the booster and M/C from a V-8 Fox Stang work as a direct replacement for my standard issue parts? I have access to them in great working order,and I think I need to swap the M/C,so the booster isn't much more work.
You didn't say what year, but since you have the drums on the back it should. You may need a adapter for one line, but I'm not positive about that.
Can you get a link for that? I may just get a stock replacement M/C since I have stock brakes anyway.No need to invest a lot into stock parts when I'll probably upgrade next year.
The MC shows to be the same for an 88 Mustang LX V-8 and and 88 T-Bird Sport V-8. The boosters are different between the two cars but I do know they bolt up. A 93 Mustang Cobra booster will drop right in and if you are going to the larger Cobra brakes on these cars front and back it is the way to go.

Vinnie, you have a firewall adjuster for your clutch cable,and a stock-type booster on there now?
I have stock parts.....22 years old...That's what I have.I want a Mustang booster and new M/C. I think mine have reached the end of the road....so to speak.
No he doesn't, because it won't work. I think that's what he wants to no. He never did say what year the stang parts are coming from. but they will work. as long as there late 80's or 90 ish. That cobra MC is definably a good option for him and the future.
The booster...M/C assembly is from a '91.
I've got an adjustable and a stock booster on mine, but it was a real PITA to get it in there, and I don't have very much adjustment (read: not enough) with it. A 'Stang booster is in my future.
I had to take a piece of 2x4 and a rubber mallet and a good hard slap with it to go in...on the tranny end, had to get creative with some big nuts over the end of the cable to get the adjustment I need...it works, and it'll hold, but it isn't right, and isn't "pretty", but it does what it needs to for now.
I'll scare up a pic if there's any naysayers :rollin:
I believe you,but I'd still like to see the pics.I want a fiewall adjuster as well,but I'm waiting until I install the Stang booster.
Vinnie,
If you decide go the route of full disc brakes via the SN-95 Mustangs then I would advise you not to get the booster off of a 94-95 Mustang as they do not share the same bolt pattern as the Fox cars firewall wise. It can be done but the extra $$ for the 93 Cobra booster is worth the cuss words as it is a drop in.
I run the SN-95 booster and M/C on my 93 Mustang Coupe with the Cobra brakes and ABS. The booster install was a challenge but it eventually went in. On the Bird I used a 95 GT MC and the 93 Cobra booster with the Cobra brakes but no ABS due to the Fox length axles in the rear. The booster install was a snap and bolted right up.
Both cars have firewall adjusters and no clearance problems.
Darren
Lies! I just got mine installed and it took most of yesterday! I shortened all studs like 3/4 of an inch. and had to grind away the two innermost firewall holes quite a bit at a 45 degree angle towards the middle of the car, along with add a slight angle to the outer firewall holes. Then with a rubber mallet, it popped in but my paint job on the booster is now shot. A lot of put in place, pull out, and repeat. Even with things disconnected, the main wiring harness and ac line were a pain. I put tape over my valve cover but I still got a chip in my powder coat.
I'm not sure why I had to go through such extremes but it's in and works so much better than my stock, leaky booster. 1 1/8" MC.
People should know that there's a chance that the booster upgrade may not be as easy as some people claim on the internet. I'm thinking it's slightly variances in booster and chassis. I know the studs on the reman booster were about 3/8" longer than the stock one so removing that much from the studs wasn't enough. At least it's in now...
A 90 mustang booster works. why make this thread so complicated.
If all you want to do is get a fire wall adjuster working it's all you need.
It will also work with 4 disc well.
Which booster did you use, the SN95 or the 93 Cobra?
Darren
I agree!!! I replaced mine with one from with an advanced auto and it was a total bitch but now it works pier then the stock one, so I am going to get one from a parts house. I guess I am going to get one from a mustang since I need that adjuster.
Again, what was the replacement unit? Stock, SN95, 93 Cobra? Without knowing this you guys are not helping out here. Others will read this thread and think this is mission impossible or something. The SN95 unit was a battle on my 93 Mustang Coupe but the 93 Cobra unit was a bolt in on my 83 Bird. Maybe I was lucky or something.
Darren
Sorry, the stock unit one or two of the bolts were a bitch!!!!
I just went thu and installed the 88 TC brakes on my 85TC, even the rears disc
replaced the booster with a reman 85TC unit $76 Advanced auto parts
and I used a 84/86 Mustang SVO Master cylinder $20 Advanced Auto parts
The SVO MC is an Alum unit with large wells and 1 1/8 piston
So the stock replacement booster gave you this much trouble? Wow, sorry to hear that as I have replaced a couple of stock booster and while they are not fun the hardest part I had with them was bolting them down. Those nuts are not fun to get to under the dash!
Darren
Yeah, the nuts were a pain, not the hardest thing but pretty sucky.lol
I guess I should have quoted more...it was in reference to the previous sentence.
The 93 Cobra did not go in smooth at all. The bolts under the dash were easy, as long as I ignore the fact that it was in the early afternoon of a sunny day. 14mm deep socket, universal joint, Two 6" extensions, and a ratchet got them out and back in in no time. All my problems were with the strut tower. I still have the stock pad over the corner of the strut tower so it may be slightly easier with that removed and additional clearance but I'd prefer to leave it there to prevent the paint from getting sed up.
Basically I took some grinding stones (I only had the py dremel orange ones on hand) and ground away the two holes near the center of the engine bay at a 45 degree angle towards the middle of the car. I do not mean 45 degrees down the firewall, but holding the rotozip at a 45 degree angle to the firewall sheetmetal. This was cut towards the center of the engine bay about 3/4". I also did this to the outside 2 holes but just 1/8" or so - just to clear. The cuts went down to the firewall material that is between the engine bay and cabin sheet metal. I tried not grinding away at that stuff but the unit wouldn't go in. I did not go all the way through it so on the cabin side, there is still some of that . Try not to breathe that dust in...
The studs on the booster were cut shorter about 3/4 inch total This allows the nuts to grab enough where the studs still stick out JUST beyond the nut. Rubber mallet and it tapped into place. The booster housing is a little more shoved in where I hit it but it works fine.
Pedal feel is great, but slightly more touchy than other newer cars I drive. It takes next to no effort to bring the car down to a quick stop. 73mm up front with ceramics, TC rear with organic, 1 1/8" MC, stainless hoses up front and stock replacements in the back and rear intermediate, adjustable proportioning. Freshly changed and bled fluid.
The motor was out of my car when I did this but I have done a couple with the motor in the car and it was a bit tougher but again not bad. I have also done a couple where we had to literally put a nice dimple in the shock tower to get the larger 93 Cobra or SN95 booster installed. We chalked this up to the less than stellar tolerances the Fox cars were assembled with. The thing that was not fun about the SN95 units were the studs that go through the firewall. The are not on the same centers as the Fox units which is why I like the 93 Cobra booster better. The only reason we go to the bigger boosters (93 Cobra and SN95) is due to the larger Cobra brakes.
Darren
So I've got a SN95 master off a 2002 GT and the 73mm front calipers and a TC rear end. Am I to understand that this might actually work correctly as far as pedal feel is concerned? I know what I'm in for as far as the fabbing is concerned and is no big deal.
Not sure on the newer '02 master cylinder but I have no complaints with the 73mm front/45mm rear with the 1 1/16" bore master cylinder when using the '93 Cobra booster.
