I stripped my eng bay for paint. I have read some post on a TII brake booster upgrade. I tried to install it on my SA and it covers 1/2 the hole on the clutch master cylinder. Is the FC N/A booster a little smalller? Any Ideas? Thanks

I'm with ya, I got a GTU booster that I want to install in my 82' GSL after I do the brake upgrade.

Can you measure the width on the booster you have? Just want to compare the size with a TII one.. I might need a N/A booster

The TII and S4 GTU boosters are the same, they both have the 4-pot front brakes. You might look for the S4 booster for the single pot brakes. I don't know if they will be much different than an SE booster though.

wow that thing is ginormous!!!!!! does it fit? Does it add alot more pressure/feel to the brakes or not really?

Huh,might be something different about the SA.

My S4 booster came from a TII and it fits with just a little grinding on the side of the clutch master cylinder.
I could see the SA brake booster being smaller than the FB's,but I dont know why they would put the holes in the firewall closer together.
Is it possible you have a S5, 4 pot brake FC booster?Could be larger still,than the S4's...(which JUST barely fits)

Removed it from a S4 TII parts car i just got.. Might try a S4 N/A.. Think it's the same size as a TII one?

steve84GS TII

S4 big brake cars have a 9" vacuum servo,the base S4 have an 8".

Trim level,not engine type will determine the brakes.For the S4's,only the 4 lug base cars had the small brakes.The GTU,VERT,GXL,Sport and TII all had the 4 pots.

i have a T2 booster, MC, and prop valve on the way to me. so this wont work on an SA? ...crap

gonzz

It won't work on mine.. when you get it let me know.. might be a rhd thing..

steve84GS TII

Ahhhh....................

Thats the variable I was missing.
It could still be an SA thing,but Id be more prone to think its a difference between the J-spec and U.S. spec bodies.
