boggles the mind
alright guys, this is not a ford question persay... however it is very vehicle related.
i have a 2000 grand cherokee laredo, it has a terrible wobble to it whenever i hit the breaks. as i compress the pedal it gets steadily worse. as soon as i let off the breaks it stops and drives fine. i have replaced front end parts and shocks and tons of other stuff. is it possible that the calipers are not functioning properly? it has twin piston calipers.... any kind of help would be real appreciated. thanks
if you need anymore info let me no... im not a member of any jeep forum and i trust the knowledge here. thanks a ton

what they said...
Jack up the front, spin the wheels. See if there is a rub or grind in full turns on both wheels. If you have an assistant, spin the wheels and have them start applying the brakes. Either way will shed some light to the wobble.
Edit: If you decide on new rotors, make sure to have a shop check for any warpage before installing them and get new pads with them. I have had many folks here advise and suggest you do this 1st. I had a similar problem, but was only very slight.These were new Wagner rotors, I had only run them for about 25 miles. I yanked them back off and sure enough, one had to be "trued" up. this was on a '04 Dodge, 4x4, and I wouldn't have believed if it. when I bought new Wagner rotors for my '92, I took them to a shop across town and had them checked, only 1 was a hair off, but glad i had it done.
Also, be sure to use a torque wrench when tightening the lug nuts, so each wheel is properly torqued.

the rotors looked awsome with no pitting or obvious sign of warpage. i will change the rotors and pads and go from there. i have never had a set of rotors warped this bad. it shakes violently, almost uncontrollable. thanks everyone

Check the caliper mounts too. I had a Mopar that had a cracked mount causing severe vibration. My 87 Cherokee had a front track bar bushing fail that caused some vibration under hard braking.

understand, but the "resurface while mounted" thing exists.
A L.Schwab or Commercial around here has the machine.
Sounds like a neat concept, to true a disc in situ, although I probably wont ever bother, it would be unusual for me to consider resurfacing anymore, rather put fresh shinies on it myself at pad time because I dont skimp on pads and would not want to lose a good set over a ready to re-warp disc.
Letting them true it requires buying pads there, another stickypoint.

One hand this is a great idea .. other I think I would rather have a big old machine turning my rotors. ... IF never seen it done its pretty cool. Someone dreamed up a way to cut time. They have a machine that rolls over to your car/ truck up on a lift, it spins the rotor and cuts it while still on. No need for the guys to take all the brackets and crap off, or pop the bearings out. Just roll it under and next to it, hook it on, set, start and go work on another part as its does it's job.

Not trying to flame on Jeep/CHrysler, but I had a boss that bought a new Grand Cherokee back in 2000. He went through 3 sets of rotors due to warpage within the first 20K miles. The dealer just kept putting them on under warranty. He claimed he was told it was a common problem with those models, but that's just hearsay.
