OK guys. I need help. I've never worked on disk brakes before. I'm replacing the pads and rotors on my Hayes brakes. (Pads are pretty bad and the rotors are wore a bit too and slightly warped) The problem I'm having is that the new pads are so thick, there's no way a new rotor is going to fit between them. I've followed the instructions to a T. I've pressed the pistons back into the caliper as far as they'll go (the outside rim of the piston is flush with the body of the caliper.) The pads are in the right way, But there's just too much material there to allow the rotor to go between them. I've mic'd everything. The new pads are 4.0mm thick, old ones were 3.55mm. And the new rotor (Hayes V6 replacement rotor) is 2.00mm and the old one is worn to 1.6mm. Did I get the wrong rotor? What am I doing wrong?!
