Normally we would start by removing the front brake drums and all the brake components right down to the spindle. In our case, the suspension was completely removed during the car's restoration process and the drum brakes weren't reinstalled. In order to remove the old backing plate and install the new caliper mount, the two lower bolts holding the spindle to the lower control arm were removed. The new caliper mount was slid onto the spindle and new longer bolts were installed through the mount, spindle, and lower control arm. Two additional bolts were installed from the backside into pre-threaded holes in the new bracket.
