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.

make sure the hub is entirely flat and clean when you mount the rotor onto it. If it is not then it would feel like it is warped when it is just not sat flat. Get a dial test indicator and fasten the magnet part onto your strutt, then put the dial against the rotor so it is just touching, when you spin the rotor the needle on the dial shouldn't move very much, if it is moving then take off the rotor and put it on a different way, then try again. I can't push my pistons in by hand yet they work ok so your calipers sound fine.
OR
the master cylinder should slightly pull the pistons back into the caliper when you let off the brake so possibly the master cyclinder has a problem.

hope it helps.
