Among other things my brakes do not work. I had alot of play in the actuating shaft. I pulled the cover off and the 2 little pointy pins were on the sides of the concave part of the shaft. Do the pointy parts of the pins go in the concave part of the shaft or stay on the side. My guess is in, but it seems hard to get them there, but possible. Also with everything apart the paper thin linings on a few of the brake discs has come off. Anyone have a source for the lining discs only. According to the parts break down you have to buy the whole assembly for $700.
