Will the rear drums from my 84 2 wheel drive wagon interchange with the badly corroded ones on my "new" 92 Loyale 4wd?

2WD vs 4WD are different.

Well, it was a thought.:( Thanks, people Guess I'll consider the disc brake upgrade. I have read the posts in USRM, but didn't see any mention of a proportioning valve change. Anyone care to comment on that?

I've read that Loyales have the valve already.

I guess I should re-phrase that. I understand disc/drum systems require different front-rear proportioning than disc/disc. So should one get the correct valve from the turbo car when doing the swap?

Apologies to all. I should have read the rear disc swap thread right under my last post, which covered the prop valve pretty well, although it still isn't clear as to whether a Loyale disc/drum has the same valve as a disc/disc. I believe I'll ask my new best friend at the nearest Soob dealer to compare part numbers.;)

It's my understanding proportioning valves are only used with rear servo type drum brakes. Loyals use non-servo brakes so there shouldn't be any proportioning valves on them.

Non-servo type brakes do not have the stopping power that servo type has. When the automobile manufacturers started installing disk brakes on the front, with the servo-type rear brakes, they used proportioning valves to keep the rear brakes from locking up prematurely. Later, the manufacturers redisigned the rear brakes to non-servos so they could eliminate the proportioning valve.
