I think the disc brake booster requires a deeper bracket because the push rod is longer or something. I am not sure but so far I used nuts on both sides of the drum booster brackets and it seems to be working. I would like to see a disc brake booster setup unmolested from the factory to be sure. Fat chance of that happening Armand snip What's different about the brackets? I know the drum brakes used a single diaphragm booster and the discs a dual. The only thing I can think of that my be different is the bolt pattern on the back of the booster, or the disc booster is mounted a little higher for clearance because of the larger diameter.
