I do not know anyone turning rotors in my area anymore, just not worth it, and maybe the rotors are still good. Unless they are out of round, shaking when braking, or unless you ran on the totally worn off pad, they might be just fine. I would have them justify every part they will replace and all the labor cost and I would ask to see and give me the parts they remove, this sometimes gets a "HO this my be OK".
I just cannot figure how it can take 12 hours to do the brakes on a MH, please someone explain the "special" procedure. I think it's a ripoff.
To me it is just nuts and bolts, big nuts need bigger tools, that's it.
