rear breaks


Recommended Posts

The question is.........

 

Which D35 do you have :hmm:

 

Do you have a "new" D35 from a XJ, with the 9" brake drums, that your using on a MJ that "had" 10" brake drums??????

 

And that's why the wheel cylinders are different sizes?????

OK.......from what year???

 

I know the front brakes were changed in '91, and from my searching, the rear wheel cylinders were also changed -

 

'89 = Raybestos WC17507 (LF) WC17508 (RT)

 

'91 = Raybestos WC37844 (LT & RT) Note- bleeder is centered on wheel cyl.

 

What effect does the year change have to do with your D35's???

 

Or.....are you going to say there from the same year MJ :dunno:

I don't understand any of what you wrote. The basic question is, are the brakes on both axles 10 inches in diameter, or is the replacement axle a newer, Chrysler-vintage axle with the smaller 9-inch brakes?

ok so as it turns out the new rear end has the 9in breaks and the old one has 10in,SO can i just pull the axle shafts out of the old one and put them in the new one? is there c clips or any thing i shuld know about doing that or any problems that i might have? thanks for any help. John

The old axle will be the non c-clip style. The "new" axle will be a c-clip axle. So the shafts will not interchange. And I don't think the brakes will interchange. I am not certain, but I think the bolt pattern attaching the backing plates to the axles is different.

:agree:

 

You can not change the axle shafts that are made for a non-C clip to a C-clip, or '91+.

 

2 totally different axle shaft mounting and bearing set-ups.

 

Your best bet is to get the Correct brake parts for the '91+ axle, with the 9" drums and make that one complete.

 

And, I think Eagle is correct, that the backing plates are totally different, and not interchangeable.
