    I'm working on my buddies 02 and his rear drums are not working at all. Needs new wheel cyl. Somewhere I heard of using a larger gm wheel cyl. Ring a bell for anyone??
    I searched but the general consensous is to toss the D35 as far or farther than you can throw it but he allready has the superior axle and arb locker in the axle. He does have a bent shaft though from an accident last year that I just saw. Sooo, I may be trying to get him to go the 8.8 route.


    But, in the meantime, and cheap route...
    anyone heard of using that larger wheel cyl for the rear 35???

    What's wrong with the factory part?

    He's got 35's on the jeep.

    Someone at work told me about the wheel cylinders. Something about having more pressure so it helps stop the drum brakes better.

    If it was a stock jeep I'd toss the factory parts at it no problem.

    Yup....
    I haven't heard of the Chevrolet mod but you've got me curious. Maybe a CJ wheel cylinder for 11" brakes? I don't know if the bolt up is the same. Would probably need brake line adapters. Larger Id would cause a lower brake pedal. Probably not by much but something to think about.

    "How many folks do you know that can actually even tell when their drum brakes fade?"

    I can. Big Bear California. Stock 9 inch drums down the mountain, extreme fade. Strongly questioned if I would survive.

    I too am reminded why I don't use Jeepforum.

    Know the parts guys/girl at carquest in town. Guess I'll check out what they have. start with the abs/non abs versions and see what he has on the jeep to start with. going with a smaller bore wheel cyl should give a little more pressure on the brakes. I'll go the smallest incriment first and see how it works.

    Thanks for the links lynn. That one was quite the read.:rofl:

    Wrong direction. You need a larger bore size to build more pressure. Smaller bore size will give less pressure but faster movement. that's why more pressure equals lower pedal. You have to push more fluid with the m/c.
    Basic Pascal's Law.

    something happened to my last post...

    Your right. wasn't thinking straight last night I guess.
    Smaller bore would apply brakes faster, but less pressure. You'd need to stand on the pedal to get the same amount.
    Bigger bore you would have to press down farther, but it would put more pressure to the shoes.

    Ended up getting the stock ones for his jeep. If it were mine, I'd experiment a little, but he's an hour away so I don't really want to go over there to fix it if it's not working good...
