Would like some comments/thoughts. I did a complete brake job on my n2009 Knight 41 SKQ (drums, shoes and new hardware). The drums were [overheated and hardened mso that they could not be turned. When the brake shop crossed numbers from the original drums they were going to cost approximately $2000.00 each. They recommended using drums from a 10 wheel dump truck that had more than 10,000 lbs. gross weight rating than the maximum for my motorhome (33,000 lbs.) The dimensions of the drums for the 10 wheeler (50,000 pounds max gross weight - less than $200 each) were all exactly the same as my old ones, but there was some difference in the heat treatment.
I have gone approximately 9,000 miles since completing brake job and everything seems great even during a couple of hard emergency stops.
Has anyone done something similar? does anyone have concerns because of heat treatment difference? I could replace these new drums 10 times for the difference in cost and as long as they are good for the heavier 10 wheeler I do not see the difference.
