(b) If anchor bolts were removed, install anchor bolts using arbor press and a holding fixture.
Install washers and nuts. Torque nuts to 90 inch-pounds (7.9 N.m.).
(c) Install O-rings on pistons and lubricate.
(d) Place pistons in cylinder bores and insure pistons and O-rings are in proper alignment
(e) Press pistons into cylinder bores hand. If required, tap the pistons squarely with a wooden
or plastic mallet while rotating pistons.
(f) Install brake linings. (Refer to 32-42)
CAUTION: Care should be exercised to prevent over tightening the inlet fitting which
could result in cracking of cylinder casting. Finger tighten the inlet fitting,
rotate one to two turns to obtain proper installation orientation, and torque to
specified value.
(g) Install inlet fitting and torque to 40-50 inch-pounds (4.5-5.6 N.m.).
(h) Install bleeder fitting, seat, cap and torque to 40-50 inch-pounds (4.5-5.6 N.m.).
Note: Cap fittings if brake is not being immediately installed on the airplane.
(i) Install pressure plate lining facing away from pistons by sliding over anchor bolts. Ensure
pressure plate slides freely over anchor bolts.
(j) Install back plate with attachment bolts and washers.
(k) Install cylinder assembly in torque plate by sliding anchor bolts into torque plate bushings.
Note: Dry film lubricants such as silicone spray should be applied to anchor bolts
and torque plate bushing to assist sliding motion. Exercise care to insure
that linings do not become contaminated with fluid or lubricant. For best ser-
vice life, cylinders must slide freely in torque plate.
(4) Installation - Brake Assembly
(a) Acquire necessary tools, equipment, and supplies.
(b) Orient and install torque plate on axle flange with bolts, nuts, and washers. Torque to 160-
190 inch-pounds (17.6-20.9 N.m.).
(c) Install wheel assembly. (Refer to 32-41)
(d) Remove back plate attachment bolts, washers, and back plate.
(e) Install cylinder assembly in torque plate by sliding anchor bolts into torque plate bushings.
