took to the hills today for brake testing, all seemed to work well
with one exception. Wheel bearing oil seals had dried and stiffened causing
unwanted friction/drag. Didn't have the CRC with me to enable correction,
so will roll it out again later today, it could help with the pushing up hill too.
The new sail arrangement is still not ready, coming soon May need
small wear pads on underside of driving platform as it catches when one does
wheely, makes disconcerting scraping noise on contact with bitumen
