MAINTENANCE MANUAL STEMME S12
• Remove transparent exible hose and check nal brake uid level at brake uid reservoir.
• Perform functional check of brake system in accordance with pre-ight check, described
in the S12 Aircraft Flight Manual, chapter 4.
7.5.1.6 REPLACEMENT OF BRAKE LINING
The linings must be replaced at the latest shortly before the attachment rivets are exposed.
The wheel brake calipers are provided with brake pads on both sides of the brake disc.
For replacement of the brake pads, the brake calipers can be removed by undoing both 1/4” bolts.
CAUTION
Do not actuate the brake at this time, as this could force the brake pistons out of the calipers. It is
recommended to temporarily insert suitable blocks (wood or similar) into the calipers to prevent
this in case of inadvertent brake actuation.
The pads with the riveted brake lining can now be replaced by new ones.
7.5.1.7 REMOVAL AND INSTALLATION OF LANDING GEAR LEGS
• Loosen all attachments to the frame.
• Remove locking screws in front of the main bearings.
• Push the bearing bolts out to the front and to the rear, respectively.
Installation is carried out in the reverse order.
7.5.2 TAIL WHEEL
Description: See section 3.5.2
Lubrication: See section 6.5
• Support tail cone to check tail wheel. Fully deect rudder pedals left and right and check
clearance between wheel and fuselage structure (and additional fairing, if applicable) and
ease of operation.
• Check condition of fork (cracks, corrosion, deformation).
• Check condition of tire and observe the slip mark. The tire wears down within a relatively
short time, since during maneuvering on the ground, the high inertia moment of the wing
span of 25.07 m / 82.25 ft. counteracts the steering force.
INFLATION PRESSURE OF TAIL WHEEL TIRES
2.8 ± 0.2 bar / 41 ± 3 psi
