i installed new pads yesterday and ran into a problem,with the pads in the bracket it was nearly impossible to get the calipar completly over them and bolted to the sliders??? once i was able to do that this caused the bottom of the metal pad backing to rub the hub/center part of the rotor. i've done a thousand brake jobs on other cars and i've never seen this! the clips on top of the pad just get flattened down when you put the calipar over them,correct? why is there no bracket/pins to keep the pad against the piston?
