Brake Inspection
The brake assemblies and linings should be checked at every oil
change (50 hours) for general condition, evidence of overheating, and
deterioration.
The aircraft should not be operated with overheated, damaged, or
leaking brakes. Conditions include, but are not limited to:
•Leaking brake fluid at the caliper. This can be observed by
checking for evidence of fluid on the ground or deposited on the
underside of the wheel fairing. Wipe the underside of the fairing
with a clean, white cloth and inspect for red colored fluid residue.
•Overheated components, indicated by discoloration or warping
of the disk rotor. Excessive heat can cause the caliper
components to discolor or cause yellowing of the part
identification label.
To inspect the b rake as sembl ies :
1. Remove main gear fairing. (Refer to AMM 32-10)
2. Wipe off any debris from brake caliper assembly that may obstruct
inspection.
3. Check brake linings for deterioration and maximum permissible
wear. Replace lining when worn to 0.100 inch (2.54 mm).
4. Inspect temperature indicator(s):
a. Clean and inspect temperature indicators installed to brake
caliper assembly.
b. Verify temperature indicators are firmly adhered to piston
housing.
c. If either temperature indicator is black, the brake assembly
has overheated. The brake linings must be inspected and the
O-rings replaced.
5. Check brake assemblies for evidence of overheating and/or
deterioration.
6. Install main gear fairing. (Refer to AMM 32-10)
