Jacking Bolt

Collapsing the shoes is not the answer. That has to be done when a ridge of rust build-up is so big, it prevents the drum from sliding past the shoes. The bolts you're referring to are needed on most import vehicles because the center hole of the drum fits onto the hub so tightly.

Those bolts are nothing special, but I would use a grade 5 or grade 8 hardened bolt to insure the threads don't peel. You can find these at any hardware store, Home Depot, Lowe's, and places like that. Run two bolts in evenly to pull the drum or rotor off. The bolts only need to be a half inch long to do the job, it's more comfortable using one to two-inch-long bolts.
