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.
(f) Install back plate and back plate attachment bolts and washer. Torque to 75-80 inch-
pounds (8.5-9.1 N.m.).
(g) Uncap and attach hydraulic line to cylinder inlet fitting.
(h) Bleed the system. (Refer to 32-42)
(i) Install main gear fairings. (Refer to 32-10)
(j) Perform Adjustment/Test - Conditioning Procedure for Organic Brake Linings. (Refer to 32-
42)
C. Inspection/Check - Brake Inspection
(a) Disassemble brake assembly. (Refer to 32-42)
(b) Check brake lining for deterioration and maximum permissible wear. Replace lining when
worn to 0.100 inch (2.54 mm).
(c) Inspect brake cylinder bores for evidence of scoring and deterioration. Replace scored
cylinders.
(d) Replace all packings and O-rings upon reassembly.
(e) Reassemble brake assembly. (Refer to 32-42)
D. Inspection/Check - Brake Disk
(a) Disassemble wheel. (Refer to 32-41)
(b) Inspect brake disc for cracks, excessive wear, scoring, mounting hole elongation, corro-
sion, and warping.
(c) Remove corrosion and blend out small nicks using fine 400 grit wet or dry sandpaper.
(d) Replace brake disc if worn below 0.327 inch (8.306mm).
(e) Coning of disc in excess of 0.015 inch (0.381 mm) is cause for replacement.
(f) Reassemble wheel. (Refer to 32-41)
E. Brake Linings (See Figure 32-421)
(1) Removal - Brake Linings
(a) Acquire necessary tools, equipment, and supplies.
(b) Remove back plate attaching bolts and washers
(c) Remove back plate.
(d) Slide brake caliper out of torque plate bushing.
(e) Slide pressure plate assembly off anchor bolts.
(f) Using arbor press, remove rivets attaching lining to pressure plate.
(g) Using arbor press, remove rivets attaching lining to back plate.
(h) Separate lining from pressure plate/back plate.
(i) Clean pressure plate and back plate surfaces of dirt and grease.
(j) Inspect pressure plate and back plate for excessive corrosion, visible damage, or exces-
sive warping.
