Pickup is a 2002 Dodge Ram 1500 4 wheel drive. A brake pad must have stuck to the rotor and tore off. I do not drive this pickup much. One side of the rotor was gouged up some so I got a new rotor and set of brake pads. I did the other side as well and it went right together as it should. On the drivers side everything is put back together except dropping the caliper into place. Bracket which holds the caliper is on and new hardware is one the bracket. Brake pads are inserted into the hardware and against the rotor. The problem is I cannot get the caliper to set back into the bracket and over the rotor. The little rubber boots that protect the two bolts/bushings that the caliper slides on just can't get pushed back enough to allow everything to drop into place. I have done many brake jobs and this one has me confused as to why it will not fit together. Any ideas? Thank you.
