My rear rotors will warp before my fronts and they start to drag after 25K the pads get replaced about 50K.
(I sued Honda over this and oil leak in under the lemon law.) They usually get cut once then warp again. After the new pads I notice a few mpg increase! They were last changed out at 75K. Now I was loosing MGP again 100K so it hit me Hmmm the rotors are hanging up? (went over this with the rep a few times no good) Greased everything really well this time and put in ceramic pads at 100K. The ceramics are suppose to give heat up better and maybe this will help. When the rotors warp again I'm going to slotted rotors. I think the problem is in the screwing in of the caliper piston. Once it gets so far out I think they hang there.
Don't know just my .02 cents and that ain’t worth too much.
