Reassembly Of Metallic Linings To Caliper - Thrush Aircraft S2R–T660 Maintenance Manual

C. Inspect pressure plate and back plates for excessive warping. Straighten pressure plate too
less than 0.010" flatness.
D. Check lining attachment pins for mushroomed heads or other visible damage. Damaged
pins may be replaced by carefully drilling out the pins (refer to Fig. 6-3).
1. Install replacement pin in holes in pressure plate or back plate with tail of
pin sticking out the counter bore side of the part.
2. Hole locations in pressure plates / back plate should allow installation of lining after
pin upset.
3. Place pins and pressure plate or back plate on a flat metal surface.
4. Using Cleveland's 199-1 Rivet Set Kit orbital or screw type press, install pins on
pressure plate or back plate.
5. Check to be sure pins are tight and movement free with no distortion of parts.
6. Refer to (Fig. 6-3) for Pin installation acceptance criteria.
E. Apply a light film of spray adhesive (3M Super 77 or equivalent) to metal backing of lining
and install lining segments onto pins. Check to insure metal backing is tight against the
pressure plates / backing plates.

REASSEMBLY OF METALLIC LININGS TO CALIPER

A. Carefully wipe dirt, grease, etc. from cylinder, pressure plate, and portions of piston
extending beyond cylinder face, and push piston back into cylinder.
B. Slide pressure plate with new lining over anchor bolts and install brake caliper into torque
plate. For equipment that is operated in an amphibious environment, or in extremely wet
climates, lubricate the anchor bolt with Lubriplate. For equipment used in a non-amphibious
environment, or in extremely wet climates, lubricate the anchor bolt with a dry film lubricant
(silicon spray). DO NOT USE GREASE OR OIL. These materials will attract dirt enhance
the wear of the anchor pins.
C. Install back plate attachment bolts and washers in brake caliper.
D. Install insulator shims (typically used with metallic lining) and spacers as applicable.

AIRCRAFT MAINTENANCE MANUAL
The adhesive is used to maintain position of lining until the
brake is assembled onto disc, and will be burned off in the first
few stops. Lining will remain in place on assembly trapped
between the brake disc and pressure / back plates.
