I have the HFX-9s, nothing fancy at all, but they work. Recently I found I needed to adjust the pads, and took my rear wheel out. I found the pads very close, and tried spreading the pads with a screwdriver, when first installing these brakes like a year ago, the pads spread just fine, but now they dont budge, they will spread, but come back to the original position really close together. I also cant seem to get the pads out. I try using pliers and pulling the pad's tab close to the center of the caliper and puling outward, but no luck. Any ideas? Are these brakes trashed, or do they need a bleed in order to get my pads further apart?
