(2) Emergency Operation.
(a) The emergency brake cable (17)
attached to the towing vehicle
pulls on the emergency brake le-
ver (19) when the trailer breaks
away from the towing vehicle.
The lever movement forces the
master cylinder (3) to release
brake fluid, braking the trailer as
in normal operation.
(b) The trailer brakes can be re-
leased quickly by pulling on the
emergency brake release cable
