Interesting you should come up with the loose wheels bearings idea, at
Pikes Peak International last year, I had a similar problem with the brakes,
only the pedal would suddenly come back up while I was on the brakes. On
inspection, we found that the outer wheel bearing had died , and the rotor
was going from an out of line condition to an in-line condition, pushing the
pads back, and then coming up hard as the pressure realigned the rotor to
the direction of rotation. Something I'd never thought about before. Just
goes to show, It's Always Something
