Hi Guys,
I have three questions about brakes:
1- What is the generally accepted maximum machining diameter for 11" drums? The factory manual doesn't mention anything, nor do the other manuals I have. My local brake supplier says generally 2mm increase in diameter is max, mine are 1.8mm over and are showing 0.1-0.2mm out-of-round when bolted up to the hubs.
2- What is the milled area for on the outside of the rear drums? The machining is about 80mm long only on one side of the drum. Both rear drums are very out of balance and this area falls to the lower side statically so I'm guessing it was an attempt at balancing. Further, does anyone balance drums?
3- Are replacement drums available at reasonable price/quality?
Thank you,
Andy.
