On another note, I am once again having a sticking piston problem with my Avid Juicy 5 brakes. After using Hayes for 5 years, I switched to using Avid. The braking power and modulation is nice, but these brakes have been a bit troublesome. Also, the clearance between the rotors and pads is very small so if your rotor is even a slight amount out of true there is some rub. Nothing major but annoying none the less.
