2wd vs. 4wd Disc Brakes

[mud4feet]

OK - I've done disc brakes on my old 2wd POS's back in the day - mudwoman's YJ (and before too long my TJ) needs some front brake work. The rotors will definitely need turned (hopefully not replaced - scored pretty bad). So what differences am I lookin' at here (haven't gotten off my sorry a$$ yet to investigate). What are the differences 2wd vs. 4wd in doin' the front brakes? Rust, I'm lookin' forward (?) to, but how 'bout the wrenchin', things to be removed?? Help me out, "Z"ers.

RE: Good rim/tire size for a TJ w/ 4" Skyjacker lift?

Simple, likely the same as the 2wd vehicles you've done in the past. Remove the caliper and the rotor will come off. Have it turned down. Use a c-clamp to run the caliper piston back in and install the new pads. Reassemble. That's it.

No hub issues? Sounds too simple........looks like I'll be wrenchin' this week. Thanks Bounty.

Where do I find one?

If you are taking off the rotor, then you will need a special spindle nut socket. I bought mine from www.4wd.com Also be careful of snap rings that are hidden in grease. Here is a writeup for dissasembling the outer ends on the dana 30: http://www.jeepland.net/d30art.shtml

Just like Bounty said.
Not having that locking hub assembly/rotor hat/dual bearing setup, like the older stuff, makes the brake jobs a breeze.

No special socket needed, and no snaprings to worry about. The '87+ D30 front axle found on the YJ/MJ/TJ/XJ/ZJ has the sealed hub assembly in which the rotor simply slips over the hub. Remove the caliper and the rotor comes right off (unless you've never removed the small retaining clips around 2 of the lugs). No need to reuse the retaining clips.
