I did a conversion on my 91 NA (don't know if its a GLX, GTU or what), it has P/W, P/S, P/L, sunroof, heavy *** hood, non LSD, and sinngle calipers.

No need to change the discs, however the rear ones on the single pistons FC's have a solid rear disc vs the double pistons caliper FC's that have a vented one.

All 5 lugs FC's use the same brake pads........

As mentioned before, you need:

- Front Calipers
- Brake lines
- Hard lines (it goes in between the caliper and the brake lines) <----- you can make your own

It is a very easy job, I went thru and got myself some nice HAWK HP (the cheapest ones), and braided lines. My car stops on a dime, I LOVE IT!!!

The only thing I don't really like is the squealing, but once I hit the brakes....................It's all forgotten

 

ok, so for brake swap you don't need hubs?

and brake lines are absolutely needed and BMS's aren't...? just clearing things up.

 

on s4's the rear are different, the calipers on standard brakes are smaller as well as the rotor not being vented. I have had to fit a standard rear caliper on a vented rear rotor. They fit but have to have thin pads!!!!not a very good fix.

 

ok i got the calapers with the hard lines will the hard line hook up to the old single piston lines from the shock.

 

Bump please anyone need info Quick
do you konw if single piston brakes will use the same line if i were to put 4 piston calapers on my car i got the hard liine on the 4 piston calalper will it adapt to the existing brake line attashed to the shock.

 

When I did my swap from the 4-lug single piston to 5-lug 4 piston, I was told I needed the proportioning valve from the 5 lug car. If I didn't, the front-to-rear braking balance wouldn't be correct. Also, I was told that I needed the booster from the same car, as it is a little larger. But I think the master cylinder itself is the same for either brake setup.

 

The hard lines that comes with the 4 piston calipers will replace the strut-mounted hard line that is on the car now. That new hard line should connect to the existing rubber hose (which is then connected to the chassis-mounted hard lines and the master cylinder respectively).

 

Thanks thats what i need to hear

 

Exactly!

 

its that posible guys or not just swap the calipers and lines and keep the small rotors?
