keep bashing on them with the hammer then I guess :shrug:
The times I have taken mine off I didn't have to mess with the parking brake shoes, just some good motivation from a 5lb sledge, first time was only a 16oz hammer :doh:
All that is holding them on the studs would be grime/rust around the studs and mounting surface and the parking brake shoes so don't worry too much about beating on them. I supposed you could maybe use a pry bar against the caliper mounting bracket, but thinking its just gonna be some brute force to get them to come off. Worst case the inside where the shoes wear has a small lip thats holding the rotor to the axle, but the rotor would be wiggling if that is the case.
