Re: semi-metallic vs. non-metallic brake pads
The best pads out are the ceramic's. akebono's are the only brand we install here at the shop, we've tried other don't last as long and make nosie, alot of newer cars and trucks use them , the chevys get 80,000 plus out of them, and you can't use semi metallics in there place, the brake system isn't designed for them , they won't stop nearly as quick and causes the abs to kick,
on to your problem, I would check to make sure you don't have a frozen slide, and then try to push the piston back in, if its hard to push back in, open the bleeder and see if it goes in easy that way, if it does i would put a new hose on it.
