And at only $20 for rear brake pads.. . you may have the same problem in the future. Not all pads are created equal and you want to make sure you purchase pads that will wear down and not cause the rotors to wear down. I'm not aware of high quality pads that only cost $20... I could be wrong and am prepared to be corrected. Personally I have very good luck with wagner thermoquiet pads on the front and the rear. I know the new front pads for my LS cost over $40 from O'Reillys... maybe I just paid too much.
Also, rear brakes don't vibrate.

You don't *have* to, but you should. Otherwise, you risk having vibrations again. And you really can't tell warping from the looks.

The braking with the wagners seem fine but they do squeak upon first drive lots of times and I can actually see that the rotor is going to have to be shaved without even running my finger across them. I installed brand new centric rotors when I put the new pads on. The rears still look good though.

If it's an older model with a sliding caliper setup, did you check to see if the slide pins aren't seized? MANY shops and people fail to use the right lubricant on those - I've seen Permatex's brake grease cause a lot problems here - use ONLY Toyota Rubber Grease, if you can't find that a SILICONE-based grease like Dow Corning 111/3M Silicone Paste(and its GM/Ford rebrands) or Sil-Glyde will work just fine.
And all brake calipers aren't immune to corroded pistons/bores and bad seals as well, you can check for those by peeling away the caliper piston boot carefully and look for torn seals, leaks or rust. Pulsations are usually a rotor issue, but a mix of bad brake pads and seized calipers can cause this. I'm running the Wagner ThermoQuiets on my fronts and they are a decent pad - but OEM or OEM supplier(Akebono or Advics) is probably better.

Here's my 2 cents......I have a 1994 LS400......I replaced all four tires(Pirellis), rear rotors (Brembo), rear brakes (Toyota), front lower ball joints (Beck Arnley).....still have front vibration when braking....took car to Midas, was told front rotors are WARPED. I'm replacing them this weekend with new rotors & brakes.....hopefully this will do it!
