paulpicard Posted September 30, 2007 Share Posted September 30, 2007 Will the rear drums from my 84 2 wheel drive wagon interchange with the badly corroded ones on my "new" 92 Loyale 4wd? Quote Link to comment Share on other sites More sharing options...

DaveT Posted September 30, 2007 Share Posted September 30, 2007 2WD vs 4WD are different. Quote Link to comment Share on other sites More sharing options...
paulpicard Posted September 30, 2007 Author Share Posted September 30, 2007 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? Quote Link to comment Share on other sites More sharing options...

DaveT Posted October 5, 2007 Share Posted October 5, 2007 prop valve bump?? I've read that Loyales have the valve already. Quote Link to comment Share on other sites More sharing options...
paulpicard Posted October 5, 2007 Author Share Posted October 5, 2007 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?

paulpicard Posted October 6, 2007 Author Share Posted October 6, 2007 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. Quote Link to comment Share on other sites More sharing options...
Ginger48 Posted October 6, 2007 Share Posted October 6, 2007 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. Quote Link to comment Share on other sites More sharing options...
