sounds like a warped rotor for sure, possible not seated right on the lathe when turned or not seated properly on the hub.
try taking the rotor off and checking the back of the rotor where it mounts for any rust build up. Usually if a rotor is turned PROPERLY you can get any warpage out of it to an extent with leaving the proper .030" for wear, unless theyre really messed up. he may have forgotten to use a vibration band or wheel when turning it. or just get a new set of rotors.

Right away you ask for trouble with using used pads and turning worn rotors. Your messed up there. Need to mic the rotors to see if they are out of tolerence and unusable. And with the new rotors get new pads. Do it up right if your rotors are out of wear. A dial indicator will pick up out of tru if you mount it on the truck. You simply can't have wobble.

Honestly I'm not so sure on how much I took off. I've personally never turned rotors so I got my buddy that I've seen do his and other peoples a thousand times. And I didn't get replacement pads bc the ones I have on are pretty much brand new. And no I didn't turn the motor on to bleed them. I've never done it this way bc I've only done it to 70's-80's model trucks before. How do I pressure bleed them? I'm doing all of this work in my shop at my school so I won't be working on it again until Monday. My truck still stops fine but just not very smoothly and my pedal pulsates.
I'm glad you replaced them, and it worked......but as stated, you should NEVER reuse pads.
All you did was take your rotors off, turn them too much and then put them back on.
That's not doing a brake job.........in the least. Buy the Haynes manual and follow it from now on, you shouldn't run into anymore problems.

Just did my rear brakes. Between the corrosion from road salt/ chemicals, and the labor for turning rotors, i was better off replacing them. 2 new slotted/ drilled rotors and new ceramic pads. No bleeding involved cause the calipers were fine. If you do the rears, plan on new park brake shoes and hardware also because they are usually rotted too.
Warped rotors are common on these trucks, by the way.
