-4- not being powerful enough to return the servo leakage when operated slowly. To obtain satisfactory results at slow speeds the friction loads had to be reduced to 'T' arm 14 lbs. and swinging arm 20 lbs. These loads under normal braking effects decrease the clank, and without the brake is released quickly is satisfactory. The snag is that the two friction loads must be kept constant. To quieten the brake release generally, rubber stops should be fitted to the rear brake levers, foot brake pedal and front equalizing shaft stop. G.W.H. | ||
