Front brakes NOT dragging no mo'
a word of caution: this is NOT advice, it's just my experience, you might not wanna do it...
My front brakes had been dragging for a long time, wheel spun for minutes (literally) with pads backed off but was dragging when brakes seated. Would only spin a rev or so.
This morning:
1. pulled & completely disassembled both calipers.
2. "polished" all 12 pistons and cylinders w/1000 grit paper (thx for the tip Alan!)
3. replaced the pressure O rings with new ones (expensive lil fukkers)
4. ditched the dust o-rings
5. installed new-ish pads (don't know what kind, they were laying around the garage.
6. New Motul DOT 4 fluid; Mytivac-ed the bubbles out.
Whoa!!! It spins many, many, revolutions now, BIG difference, and it brakes better than ever!!

I use the bike 95% on the track so I'm not too worried about losing the dust O-rings. but... just have ti see how it holds up.

After applying the brakes, if you were to lift the front end in the air would the wheel spin freely , or would there be some drag . I am just thinking about after the burnout ,its not like you can push the pistons away from the discs to get that free spining wheel again. Don

BRAKES
Always remember to pump the brakes back up with tiny strokes instead of 2to3 big ones this keeps from rolling those seals that he took out. (it usually takes about thirty to fourty pumps) do not forget to either pump the forks or spin the wheel with the pinch bolts loose so the wheel centers on the brake. spin wheel and grab handful of brake (on stands) this centers everything.
