Brake Service; Tire Inflation - Piper CHEROKEE 180 E Owner's Handbook Manual

CHEROKEE "E"
Alignment of the nose wheel can be checked by pushing the air-
plane back and forth with the rudder centered to determine that
the plane follows a perfectly straight line. The turning arc of
the nose wheel is 22 degrees in either direction and factory ad-
justed at stops on the bottom of the forging. The turning radius
of the nose wheel is 17 feet.
The steering arm stops should be carefully adjusted so that
the nose wheel reaches its full travel just after the rudder hits
its stops. This guarantees that the rudder will be allowed to
move through its full travel.

BRAKE SERVICE

The brake system is filled with MIL-H-5606 (Petroleum base)
hydraulic brake fluid. This should be checked at every 50 hour
inspection and replenished when necessary by filling the brake
reservoir on the upper left front side of the firewall to the indi-
cated level. If the system as a whole has to be refilled with fluid
it should be done from the brake end of the system by filling with
fluid under pressure. This will eliminate air from the system as
it is being filled.
No adjustment of brake clearances is necessary on the
Cherokee brakes. If after extended service the brake blocks be-
come worn excessively, they are easily replaced with new
segments.

TIRE INFLATION

For maximum service from the tires on the Cherokee, keep
the tires inflated to the proper pressure of 24 pounds for all three
wheels. Interchange the tires on the main wheels if necessary
to produce even wear. All wheels and tires are balanced before
original installation, and the relationship of the tire, tube, and
