Attempt no #7, 854 to get the back brake to work properly on my Rudge has actually been pretty successful this time. A lot of time spent getting everything just so, straightening the linkages and removing as much play as possible mean it's now possible to lock the back wheel
Rod brakes get a bad reputation but I do wonder what they were like when the bike was new and before 70 odd years of wear created a lot of slack. It's easy to get the front working well enough but the back brake has a lot more points for wear. You can see the groves in the bolts. It's tempting to drill and ream out to the next size up and fit new bolts. I assume they are some sort of hardened steel.
Nice leisurely 30 miler in the evening visiting the stone circle en-route.
