Keep warping rotors, im really frustrated!, Getting warped for the 3rd time Options

[eliaz]

Ok, so having replaced my front discs for the third time I can notice that the rotors is being warped again. I have only driven 250 miles with my new set and I can now feel that they (or maybe just one of them) are slightly warped. I replaced the new discs with OEM toyota discs and EBC greenstuff pads. I have noticed that the right disc is much warmer that the left one. Ok, so I thought that the caliper is stuck somehow. I have overhauled all four calipers about 6 months ago. Today I took out the caliper and both sylinders, all seems fine and the slide without any prob. I can push them into the caliper body with just my fingers! I tried a testrun without no braking at all and I can say for sure that the right disk are warm (let's say about 115F), so the caliper are not retreating fully? Not working 100%? I have no more ideas, I really hope someone can help me. I am getting really frustrated

Edit: Oh, I've been really careful when braking.

one other quick check you can do is check pedal free height and free play. if the pedal is over adjusted
it can cause the brakes to drag. free height is checked using a ruler, held next to and perpendicular to the
part you put your foot on, measure to the highest point on the ruler that the pedal reaches (without touching the pedal), try to make sure the ruler is touching the metal behind the carpet. here is a picture, look at page six of the br section.
note the specs are for a g35. i seem to have lost my dam chilton, so if anyone can post the specs thatd be great

pedal free play is checked using the same set up, but wiggle the pedal up and down WITHOUT pushing
the brake booster. if there is no free play then the pedal is overadjusted.
