*PIPER AZTEC SERVICE MANUAL
2-56. INFLATING OLEO STRUTS. With the proper amount of fluid contained in the
strut as described in paragraph 2-53, inflate the strut to the following pressures:
Tire
Tire Pressure (psi)
Strut Pressure (psi)
6.00 x 6 - 4 ply
27
132
6.00 x 6 - 6 ly
32
151
7.00 x 6 - 8 ply
46
NOTE
Strut pressure is with strut fully extended.
2-57. BRAKE SYSTEM.
2-58. SERVICING BRAKE SYSTEM. The brake system incorporates a hydraulic fluid
reservoir through which the brake system is periodically serviced. Fluid is drawn from the
reservoir by the brake master cylinders to maintain the volume of fluid required for
maximum braking efficiency. Spongy brake pedal action is often an indication that the
brake fluid reservoir is running low on fluid. Instructions for filling the reservoir are given in
paragraph 2-59. When found necessary to accomplish repairs to any of the brake system
components, these instructions may be found in Section VII.
2-59. FILLING BRAKE CYLINDER RESERVOIR. The brake cylinder reservoir should
be filled to the level marked on reservoir, with the fluid specified in Table II-I. The reservoir.
located in the left side of the nose, shown in Figure 2-8 should be checked at every 100 hour
inspection and replenished as necessary.
2-60. DRAINING BRAKE SYSTEM. To drain the brake system, connect a hose to the
bleeder fitting on the bottom of the cylinder and place the other end of the line in a suitable
container. Open the bleeder and slowly pump the desired brake pedal until fluid ceases to
flow. To clean the brake system, flush with denatured alcohol.
2-61. TIRES.
2-62. SERVICING TIRES. The tires should be maintained at the pressure specified in
Table II-I. When checking tire pressure, examine the tires for wear, cuts, bruises and
slippage. (Refer to Card 2116 Section 7, paragraphs 7-75 and 7-76 for suggestions on tire
balancing. See Card 2J3, Figure 7-31 for information concerning construction of a tire
balancer.)
