hmm. well thanks for the info. maybe i will look into this when i redo some stuff this winterf00g00;1851989 said:The hyd brake system in the 750 , early 735 and 850 would be to complicated to install. Besides the master cylinder with "Hydroboost" and pump (two versions, 735 and 750 had self leveling rear shocks, 850 normal) and a 2 part pressure regulator/accumulator. The accumulator or "Brake bomb" holds pressure to allow you to get about 10 good pumps from the brakes with no hyd power. There are also pressure switches on there. If you could get it to work it might be "The Bomb"
