PRESSURE PLATE CONTROL

(A) The control of the pressure plate is accomplished
through the spring in the center of the clutch shaft and
two rollers mounted on the cam end.
(B) The rollers ride on an incline on the cam end, and
when on the rise on the incline, pull the spring shaft
(attached to the pressure plate) back against the spring
into the braking position.
