Why are you concerned of possibly "bent" ("warped" is the more appropriate term) rotors? Do you have some performance issue such as pulsating or chattering? If not, the rotors are probably fine.
If you really want to know, it's easy enough to check the rotors. Just put a dial-indicator, or some semi-rigid pointer if you dont have an indicator, up to the rotor and rotate the wheel. The indicator will show you the runout directly. If using a pointer, find the high and low area, and measure the low area with a feeler gauge.
Jack it up & spin the wheel if there is alot of drag in some areas more than others there is a good chance you have warped rotors or if when braking it brakes hard & releases
