I considered it, but it was going to cost a rack.

Basically, you need the entire rear suspension from an AWD wagon. New hubs, new control arms, everything.

Cost is pretty expensive, work isn't to hard.

It'd be worth it to swap to AWD while you were at it.

Drum brakes on a 95? I had no idea they had them then... The master cylinder or a proportioning valve would be different as drums require different bias. My fwd has rear discs, so if you have a fwd (which I didn't know they had in 95 either) you may be able to just get the knuckles. I don't know how the parking brake will be affected.

My 95 L FWD has rear drums. Major Suck, decent pedal feel, but lots of fade over lots of turns.

Blech! Drums! :roll:

How unfortunate that car companies are still cheap enough to make such antiquated devices... Fortunately, BOTH my cars were made at a time when drum brakes were considered as such. Guess things have gone into regression since :(

Yeah, you're gonna need new rear suspension basically, not just calipers and rotors. As mentioned, for all your work, you might as well try to make it AWD, then it will be worth it.

that sounds like a lot of work...but my car is already AWD

Whole rear suspension eh? yeah well screw that. seems like a bit much to me. maybe I'll just make the front suspensio way good, i dunno. Oh yeah, my car is already AWD, and it still has drums in the rear. oh well, thanks for the replies.

Mike Shields seems to say all you need are the hubs:

He makes it sound easy.

That's what I figured. The fwd disc brake rear knuckles have the hubs and should bolt right up. Don't know about brake bias issues or parking brake still.

HIs car is AWD, so that won't work.

If it was fwd I have a pair of hubs/rotors/calipers/pads that i'd sell :P
