did that about 6 years ago. Not a hard job to do and you will NEVER buy another trailer without disc brakes. I know I won't. Had I not had disc's there would had been a black bear in my grill one time. Another thing, I have a leaky grease seal and the grease slings right by the rotor so no grease is getting on the pads. Someday I'll get around to fixing it but no worrys, no grease on pads or rotor. I can't believe that the RV manufactuers still use drum brakes when all cars use at least one axle with disc. Oh yes I can, they might cost $2 bucks more.
