So on my "new to me" Giant AC2 I have Hayes Hydraulic Discs (I am not sure the model I will have to check when I get home). However, when I hit the brakes I find that many times the pads do not always fully retract and then the pads are constantly rubbing the disc. I ride primarily downhill and this not only makes an annoying sound but creates undue heat and slows my momentum. I am wondering if there is something I can do to correct this or if it is just an issue with hydraulic discs b/c I had the same problem with my Kona Stinky with Hayes Hydraulics. I am thinking of switching to Avid BB7's if I cant fix these. Thanks in advance for the help!
