Dana 35 rear disc conversion

So I'm toying with the idea of doing a disc brake swap on my 05 It has a d35 I found a guy on craigslist that has an entire zj setup for $150. Looking at Stu's site it seems pretty straight forward. Is it worth it? I hate my drum brakes they never seem to adjust properly.

I looked into this and what I have been able to put together from all the post is this:

If you want rear disc for better braking / decreased stopping distance...it's not really going to do that.
However it does make doing brakes easier.

I've been told to just make sure your rear is in good working order and if your looking to get better braking upgrade your shocks and your rotors +pads to a better quality.

I'm mainly thinking ease of maintenance. I do understand that the braking power is not increased. For $150 the price is right

Doesn't the rear disk brake setup on the ZJ still use drum brakes for the parking brake?

I plan on doing the conversion just for the fact the tire won't come right off, if the axel breaks. I carry spare shafts, but I had rather swap them back at camp, instead of on an off-camber, crowded, muddy trail.

If that is your plan, you need to include not having any brakes while you're using the caliper to retain the axle. If the rig wobbles and the tire causes the rotor to push caliper piston in, it will take several pedal pumps to get it back in place.

Would the front brakes be effected as well? I understand what you are saying for the rear. It would only be a "make it back to camp" scenario and I'm manual trans.

Easy to find out. After you do the swap, push one of the rear caliper pistons in by levering the caliper over with a screwdriver. Take it for a short drive with nothing in front of you and see how many pedal pumps it takes to stop it.

If you have ever put on new pads and rotors, you have noticed they are very tight fitting to get the caliper back on over the rotor. You also noticed that even as tight as it was, you still had to pump the pedal several times before you had brakes.
