Had this same problem on the Epperson 2E in 2010. Bolts kept coming loose and letting the caliper rattle around, safety wire kept them as tight as safety wire can. Snapped the bolts off flush and lost the Brakeman caliper at the L-burg Kiss race that year. Bought a new rear end while waiting for the old one to be fixed. No more problems until now.
Friday night in the SKM at Bloomington the bolts snapped off after the last restart and the caliper left the car after smacking Shane in the butt. Finished the race with no brakes. That rear end had two shows on it after being freshened by a very very good rebuilder. It also has a floating rotor mount, so axle end play cannot be the cause. The bolts were brand new grade 8's and were safety wired.
I am at a loss and looking for a different style mount that does not use just the two side bell bolts. I was looking at the Wilwood radial mounts, but it looks like the radial mount just bolts to the same two side cover mounts. Anyone have experience with some other mount that bolts to the actual side bell studs? Building a brand new car for Sprint Week and cannot afford another failure.
