I know EA82 turbo wagon's are viable donor cars.  There is an AWD XT turbo at the local yard that still has all of the rear disk components.  Would the XT parts also work to convert my hatch to rear disk breaks?

 

Thanks in advance.

Yes so go grab'em!

Awesome.  Now where did I put that followed thread that had the details???

Its pretty simple bolt in, one of the first things i did, i havent added the prop valve yet but others say its really important so ill let you decide that, whan you pull the pars pull everything from the backing plate forward and take all the rubber brake lines you can, and i would buy new rotors, oreillys initially told e they wouldnt dit in the machine to rurn them, they fot it to fit and turned but i think they aren't true now because i get an intermittent squeak out of one under light brake pressure, so backing plates the hubs that bolt to the rotors, the calipers, and the prop valve which is bolter in front of the gas tank with 4 lines coming out, take these hard lines connected to the valve so you arent making your own

It's an old write-up, but still accurate. Only thing I would do different is to shorten the steel line that used to go to the wheel cylinder (in that write-up, he just bends it out of the way). Most parts stores sell pre-flared chunks of line, too, you could just replace it with a new one.

 

Or, you can replace the 2 rubber lines and the steel with the rear hose for an EJ car and it's banjo bolt. I used Centric braided stainless for a GD ('02-'07) Impreza. It comes off the caliper at an angle, instead of straight out, so you'll have to route it out around the back side of the shock.

I replaced the rear brake lines like Numbchux did, but routed them along the semi-trailing arm on my EA81T wagon.  I was even able to reuse the little metal tabs to secure the line, using some silicone tube to prevent premature wear.

FYI, there are two lengths used for GD rear brake lines.  STI and non-STI are different lengths, I think STI are longer, but I don't remember offhand.

Thanks for the replies and clarifications everyone.  This is good news indeed!

Is it the general rule that any car with rear discs and the funky 4 bolt stud pattern should be compatible? I would think that is true... can anyone confirm that?

2WD XTs (5 lug studs) have a smaller center bore in the backing plate, but I think it's true that the 4-lug vehicles should all be compatible.
