inktoxicated

ok so i got a new noise that ive heard a few times but today it was quite loud for about 20 seconds str8, then i parked my car. when i later drove it i didnt hear it.(2 hours later) the car has 59000 miles orginal rotors. when driving the front right wheel makes a hsk hsk hsk hsk kinda noise. faster when going faster slower when going slower.( hsk hsk hsk hsk hsk hsk...... or hsk hsk hsk hsk(slow) when im next to a wall or curb its loud since the sounds reflecting. car brakes fine and makes no odd noises or pull when braking. like i said its not always there but it has started to become more frequent. pads were changed at 40k. thinks its just warped rotors? and where can i get a set of 4 for a bargain

Warped rotors would cause that pulsing sound.

Could be rotors, but if the sound comes and goes I would look at a sticking caliper piston. You might have slight warping of of rotor (not severe enough that you notice any difference in braking performance or vibration) and when the pad hangs you are hearing that light brushing. Also if it was constant I might even suggest rust or dirt between the rotor and hub when you reassembled it the last time you did the brakes but again, with it coming and going that also is unlikely.
