Bottomed out forks hard, now front brakes are dragging!

I had them set way too soft for my fat ass (230 lbs) Everything looks straight, and it handles fine. No wobbling, headshake or anything. But's the front brakes are making a swish swish swish sound that goes away when I apply them. It never did this before I bottomed it out.

Did the forks move in the clamps? Bent axle? Could I have bent the rotor?

Well, I loosened and re-tighted all the clamps one at a time, and blast the calipers with brake cleaner. The noise seems to be gone now.

Have you checked your fork seals?

Disc brakes always drag on the brake pads. If you put the front on a stand and spin the wheel, as long as you get like 2 revs or more out of it... you're good.

I know they're supposed to drag a little, but it got really bad immediately after I bottomed out the forks. It almost sounded like air leaking out of the tire at first it was so loud.

yeah sometimes oil from your fork seals can get on there if they are extremely leaky. Also if your brake fluid is old/comtaminated it doesn't help the situation. Any hydralics brake or clutch systems on cars or bikes should be running near 97 percent efficiency with low stiction to avoid wear and tear, and achieve best performance. If the fluid is contaminated by anything it can bring the efficiency below the threshold.

Current bikes:
2004 CBR600RR (daily rider, to be raced)
2006 CRF450R
1973 CG150 (off road, future restoration project)
1971 CB100 (being restored)
2006 BWS50 Zuma
Bikes of my (recent) past:
2004 Honda Ruckus, completely built, 55mph on the flats, 60 downhill and/or drafting
2007 Kawasaki Ninja 250
2004 Yamaha R6

CBR600RR Mods:
BMC race filter
Jardine slip on
8987 PENSKE triple adjustable shock
STM slipper clutch
Power Commander III

Gear up or go home!!
