MASTER CYLINDER
The master cylinder consists of a fluid reservoir
bolted to a cylinder bcdy, which· contains a piston,
seals, and other parts, as shown In Fig. F6. With
reference t9 this exploded view, and also the hydrau-
lic flow diagram (Fig. F5). the operation cf the
brake assembly Is as follows.
When the brake lever Is operated, the push rod (1)
moves the piston (2) down the bore. The displaced
fluid in
front of the piston Is forced through holes In'
the check valve (3), lifting the rubber seal clear of
the holes, to prOVide an unblocked passage to the
wheel cylinders. On releasing the front brake lever,
the retUrn spring (4) thrusts the piston (2) back
faster than the fluid is able to return from the wheel
cylinders. This creat.es a partial vacuum In the
cylinder, which causes fluid to be drawn past the lip
of the pri'l1ary seal (5) and the main reservoir, via
the main feed port (A), and the small feed holes In
'the head of the piston (2). '
