Probably the most practical modification has been to convert the rear axles to disk brakes. I highly recommend this modification, as the stock brakes are marginal at best. Its not real expensive, and is a direct bolt on upgrade. Because drum brakes depend on the rotation of the drum to activate, this means there is always a delayed response when applying the brake. Disk brakes do not have that delay, and that is often the difference between a moderate hard braking and a sheer panic stop. I never realized the delay was there, until I installed the disk brakes and it went away. Its an amazing difference to be able to stop the coach with confidence.

Could those who have done the conversion point to options available or used?
Are we looking at using new parts (vendors used) or converting using salvage parts?

I noticed your signature shows your coach as having Dexter axles. Up until 1982, Revcon used Wolverine axles. The difference is recognized by the fact that the Wolverine axles are square, and the Dexter axles are round. So it is worth making sure which axle you really have, before buying the conversion kit. Revcon did some random customization, so anything is possible, but if yours really is Dexter, it would probably be the only one.

The kit I used was this one, only for some reason it is 200+ more than what it was when I bought it. All the kits have gone up in price, but that specific kit went up more than the other ones. I specifically chose the kit with the stainless steel calipers, because stainless is a poor conductor of heat. This reduces the transfer of heat from the pad to the fluid, so the fluid is less likely to boil. Any of the 8K kits would work.

The kit is an exact fit and does not require any modifications. You will need to remove the proportioning valve, and just run the lines straight to the calipers. The OEM proportioning valve keeps about 10 PSI of pressure in the lines to hold the pads close to the shoes. This is not needed with disks, and will wear out the disks prematurely. It also screws up the response time.
The only other issue is that you are loosing the emergency brake. In my case, the e-brake never worked anyway, so no loss on loosing it. If you consider the over all safety of the conversion, it is my opinion that safety increase from switching to disc brakes far out weighs the loss of the e-brake.
