PHANTOM III FRONT BRAKES. We have carried out a test on 36-EX to see how many turns the front brake adjustment has to be released to allow the front wheels to rotate when jacked up on the built in hydraulic jacks. We find that releasing OS 2 clicks NS{Norman Scott} 1 clicks allows wheels to be forced round by hand. OS 3 clicks NS{Norman Scott} 2 " allows wheels to be turned freely enough for washing. OS 4 " NS{Norman Scott} 3 " allows wheels to be spun freely for balancing. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
