bleeding process the level is not allowed to fall below
the MINIMUM mark.
2 Unlatch the pedals, and bleed each brake separately as
follows:
3 Right Hand Master Cylinder

A, ensuring that the free end of the tube is
immersed in fluid contained in a suitable container.
b Open the brake bleed screw and apply full pedal
strokes of the right hand brake pedal until all air is
expelled.
c Close the brake bleed screw with the pedal fully
depressed.
4 Left Hand Master Cylinder
