Evening fxxxrr and greenfielder,
When the photos of fxxxrr’s handbrake photos were posted a couple of weeks go it answered a question that I couldn’t answer for the life of me when the handbrake discussion first arose when greenfielder first bought his machine and there was a discussion with gml about it. I just couldn’t see how a pulley would be utilised as a brake. I agreed with you greenfielder that the best guess was that a circular section bar would rest in the pulley. The real answer is way more ingenious! What a beautiful piece of imaginative bush engineering! I love it.

. The million dollar question is.....how well does it work.
Cheers,
I put my hand brake on yesterday as the lever was in my way while i was doing something cont remember now exactly what, possibly removing the transmission covers , or when fitting the springs , fast forward to today when i realised it was still on, ooops i had left the handbrake on while playing with the drive system, getting it running and moving it back and forth while testing, pushed it in and out of the shed while i tidied up a bit, sio i guess the answer to that question in my instance anyway is , It doesnt work LOL when clicked on it makes zero difference to the rolling resistance what so ever, when pulled on on hard past the locating slot, it barely changes it, i guess when the belt section is new it would work ok as a park brake, but if as i suspect it has been used as a brake in general and is worn out it dont
work so good

Just had a thought looking at the photos, and it would be fairly easy to bend the lever to allow it to work again and rather than it be worn out. i think the lever has been bent during use causing the predetermined slots to be not effective
