A popular upgrade to V7 / V700, Ambassador, and Eldorado models is to replace the rear wheel and drum brake with one from an 850 T. There are several benefits to doing so:

Basic installation

Installation is straight forward. Just replace the stock rear wheel, brake plate, and axle with the rear wheel, brake plate, and axle from an 850 T. I'm not even sure you need to swap axles, but I did and forgot to visually compare the axles. I do recommend the following activities prior to install:

Added spring to help return the rear brake to the non-applied position after braking. I did not find this necessary on my 850 T rear brake.

Replacing the brake stay arm

I've never liked that the cush drive does not sit parallel with the the rear swing arm. It always looks a bit off to me. So, I decided to fabricate my own brake stay rod to correct this annoyance.
