ok, first, the 500t brake came from the factory precracked. the quicker you can stop, the further you can go before slowing down. then the faster you can be back on the gas. olmstead used to lift the rear wheel of his 360 on a regular basis. 550 front end disk combo. ive been dying to get an even better brake for the 350. the stock brake i had could get overworked pretty easily on the 350. mike cooked the crap out of it and i didnt have much luck with it. but i d know more now than i did then. so that could also be part of it. if you send your entire kit out to vintager brake, and just shell out the $$$, you'll have an excellent brake. and another thing, sometime, measure the size of the cable, and check out the way the casing is made. wehn you pull on the brake lever, the casing just squishes. ive found a guy in town here who makes them out of some kind of special uber material that doesnt flex as much. anyway, id love to be able to lift the rear wheel, but i just dont think the bikes are that linear with drum brakes. they just dont get going fast enough, and arent able to slow down quick enough. it might also be an issue of suspension not to mention geometry. but i have seen mike do it alot. said there was a guy in canada who said he was getting the rear wheel off the ground about 6" so you can equate that to probably 4" still pretty cool.
