LANDING GEAR AND BRAKE SYSTEM

PA-32R-260 / 300

6-1. INTRODUCTION. In this section are instructions for the removal, disassembly, inspection, overhaul and

installation of the various landing gear and brake system components used on PA-32 series airplanes.
Also included are instructions for the alignment of the nose gear and the repair and service of the brake
system .

6-2. DESCRIPTION. The landing gear incorporated on the PA-32 is a fixed, tricycle type, fitted with three

600 x 6 wheels. The landing gear struts are of the air-oil type. The nose gear, steerable through a 60
degree arc, enables a 30 degree turn in each direction. To aid in nose wheel and rudder centering and to
provide rudder trim is a spring device attached to the rudder pedal torque tube assembly. A shimmy
dampener is also incorporated in the nose wheel steering m echanism .

The two main wheels are equipped with a single disc hydraulic brake assembly which is actuated by a
hand lever connected to a cylinder located below and behind the center of the instrument panel, or by
individual cylinders attached to each rudder pedal. The hand lever also doubles as a parking brake and
may be operated by pulling back on the handle and pushing in on the button at the side of the handle. To
disengage the parking brake, pull back on the handle. A brake fluid reservoir is installed on the left
forward face of the engine firewall.

6-3. TROUBLESHOOTING. Troubles peculiar to the landing gear are listed in Table VI-I, at the back of this

section, along with their probable causes and suggested remedies. When troubleshooting the landing
gear system, it may be found that it is necessary to place the airplane on jacks. If so, refer to Jacking,
Section II.

Release the cowl fasteners, two on each side and remove the top cowl.

Disconnect the electrical leadto the landinglightat the quick disconnect at the inside of the
bottom cowl.

Remove the bottom cowl attaching screws from around its aft end and remove cowl.

Place airplane on jacks. (Refer to Jacking, Section II.)

Place a drip pan under the nose gear to catch spillage.

To remove air from the strut, depress the air valve core pin found at the top of the strut assembly.
After the pressure in the strut chamber has diminished, remove the valve core pin, and attach a
small hose to the air valve, and drain the fluid by slowly compressing the piston tube. If it is
desirable to extract more fluid from the strut chamber, remove the filler plug, insert the siphon hose
and drain fluid from the upper area of the housing.
