One of my Avid brakes is not resetting. When I brake, the pads remain clamped to the rotor. First, I thought this was due to gunk in the cable providing too much resistance. I replaced the cable - no luck. I thought it might be the butterfly spring that hold the pads apart, but this doesn't seem to be it either. The problem seems to reside in the brake arm - whatever it supposed to spring it back is very weak.
How do I fix this?
Take the pads out and lube it?
Take it apart?
Send it back?
I did a ride yesterday with only a front brake. It wasn't so bad - only one endo from grabbing too much brake - and I jumped clear away. Still, it's a bit limiting to not have the rear brake.
