4x4 Front Rotors Question:
Had a bad vibration under braking. Took it to shop, the rotors were too thin to turn, they installed new rotors. Still have vibration , maybe worse. Everything in the front end checks out - nothing badly worn or loose. Put on a set of shocks because one shock bushing was worn out. They checked the rotors out of the box and they were true and straight. But did not turn them after putting them on the hubs. Is this really necessary? How bad could the rotor be from just pressing on to the hub?

I have had a history of brake problems on my 99 250 Super Duty. The only brake rotors that work are the OEM rotors from Ford. I have used Napa Rotors, and Robbins rotors, and they are all off just enough that they heat up and warp with one days use. They were half the price as the Ford parts. So I went back to Ford rotors and they now work fine, no vibration. Also check the caliper to make sure it is not junk. If the piston in it is pushing on the disc, it will cause them to heat up and warp. Just went through this problem last month. For the record, I am not a mechanic as a profession, so maybe some of my lingo is not technically accurate, for any of you bashers out there.. But you should get the jist of it.
Good Luck

I will echo what Maine_99SD said as true. Plus, I think your vehicle needs a special machine to turn the rotors while on the vehicle, I do not think a regular lathe will do. So, make sure you do not wear the pads down all the way.

you know to be easy on the brakes until they break in right? i have had a brand new set of rotors that turned out to be warped and needed turning before i even installed them once. make sure your breaks are not dragging...this could cause them to warp. though i have never seen it happen before, i have heard that if you over-tighten the lug nuts you could warp the rotor. just a few thoughts. good luck.
