BRAKES 15 - 3
It is necessary that rod (5) which is attached to the brake
pedal operating r o d, be adjusted for clearance where it seats
in piston (13) so that there is 1/4" free movement of the
brake pedal p ad before the pressure stroke starts. Cup (15)
is thus permitted to be clear of port (16) when piston (13) is
in its released position.
NOTE: If this port is not cleared by the piston, t he compensating
action of the master cylinder will be destroyed and the
brakes will drag.

NOTE: Master cylinder should be kept at least one half
full of Hudson Hydraulic Brake Fluid. The filler cap and
master cylinder should always be cleaned of all dirt and
grit before removing the cap. Grit in the fluid will cause
scoring of the cylinders and possible plugging of lines and
ports.
