TASK 32-10-00-810-802-A
External Leakage on the MLG Normal and Alternate Brake Quick Release Connectors - Hose to Connector Interface

1. Possible Causes

quick-release coupling
union nut

2. Job Set-up Information
A. Referenced Information

REFERENCE	DESIGNATION
AMM 29-00-00-790-001	Check of the External Leaks of the Hydraulic Components
AMM 32-11-12-960-801	Replacement of the Quick-Release Coupling
AMM 32-42-27-210-001	Inspection/Check of the Brake with the Wheel Installed
AMM 32-42-27-400-001	Installation of the Brake

3. Fault Confirmation
Subtask 32-10-00-710-051-A

A. Do a check for external leakage of hydraulic fluid from the connection between the brake quick-release coupling and the union nut on the brake hose assembly AMM 29-00-00-790-001.

NOTE: The permitted leak rate of the quick-release coupling is the same as the permitted leak rate of the brake units.

4. Fault Isolation
Subtask 32-10-00-810-051-A

A. If the leak rate is more than the permitted limit as specified in AMM 29-00-00-790-001:
(1) Do a check of the torque of the union between the hydraulic couplings and the hydraulic hoses AMM 32-42-27-400-001.
(2) Do a check for damage of the hose unions and the quick-release couplings.
(3) Do a check of the condition of the piston housing AMM 32-42-27-210-001.
(a) Replace all damaged parts AMM 32-11-12-960-801.
(4) Do a check of the quick-release couplings and the union nuts to make sure that there are no leaks AMM 29-00-00-790-001.
