Following video can be used as Installation tutorial.
IMPORTANT NOTE : We removed this video from our youtube channel and "brake strenght adjustment" is no longer supported feature. Reason is becouse more than few customers damaged brake shaft while performing this procedure - causing hole on brake shaft to widen up which lead to 1-4 degrees play on brake axis (see picture below)
It is very important to align screw hole on brake shaft to the screw itself before tightening, as noted on video !!!
