shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
