I've posted several times about the S2's front brake seals, over time, dragging.
(S1's not so much as they have half as many pistons)
This (IME) is due to rubber hardening up, grit, grime, seals don't allow the FOUR pistons (each disc) to retract.
The below video was taken today, with approx. 12,400 miles on the rebuilt calipers from 8-30-12.
I'll note the bike is pleasure only, rarely see's rain. As part of regular maintenance, I use an air compressor to routinely blow out old brake dust.
**Note, I initially spun the tire and stopped with the front brake to show the pads were NOT pushed back in, etc. They are
in their current, natural position.
I've also posted an easy way to check them it to go for ride, maybe 50 MPH and stop with the REAR BRAKE ONLY.
The front DISCs should be cool to the touch. If their hot, your brakes need attention..
Enjoy!
