Figure 12-33.-Crosssectional view of multiple disc brake.
When hydraulic pressure is applied to the pistons,
pressure is released, the return springs force the pistons
the pucks are forced against the first disc, which contacts
back to the preset clearance between the pucks and the
the pucks in the center carrier. This force moves the
disc. The self-adjusting feature is identical to that
center carrier and its pucks against the second disc,
forcing it in contact with the pucks in the housing. In
described for the single disc brakes. Maintenance of the
this manner, each disc receives equal braking action on
dual disc brake is the same as that previously given for
both sides as the pressure is increased. When brake
the single disc type.
