My brake rotors were warped about three months ago and now warped again. I don't really know what's going on but I believe that my calipers are sticking on the front. It is only the front rotors but I can't seem to figure out how to check the calipers to see if they are sticking. When I stop, sometimes it feels like the caliper on one side or another feels loose but it is all tight and seems to be fine but I can't keep this up. Gettin expensive. Please help. Is there only the piston on the caliper that should be greased?

 

When your rotors were warped, you had resurfaced the rotors & replaced the brake pads with new ones? If yes, what type of pads did you put on there? Also, try bleeding your brakes.

 

For 1 did they just simply resurface the rotors or give you new ones? Resurfacing the stock rotors is usless.

get a new set of aftermarket rotors and pads. A way to see if they are sticking is jack the front up put the car in neutral and spin the wheel if it moves freely its not sticking. I doubt your have a hung rotor, warped rotors is very common on these cars

 

Spectacura, if you have the warped rotors fixed at the dealership, they will warranty the repair for a period of time. So when the rotors warp again three months later, you should bring the car back for warranty claim.
