ive put the new pads in but cant get them to go back on rotor because of the mounting bracket...i can compress the bracket in with a c clap,, but it comes out again when i remove clap.... there is still a allen bolt in the calibur that looks like it is connected to the bracket still... am i supposed to take the bolt out also, is that why the bracket will not stay compressed so it will fit on the rotor? i have tried to remove that bolt but it is extremly tight....
