Note: 
The two forward brake lines that run between the pilot master cylinders and the parking brake valve are identical. Use the procedure below to replace either of them.
Task Instructions
1. Use a 7/16 wrench to hold the AN816-3D fitting on the forward port of the parking brake valve, then a 1/2 wrench to disconnect the B-nut of the forward brake line at the parking brake valve. Cap or plug the openings to minimize fluid loss.
2. Disconnect the brake line at the pilot’s master cylinder by using an 11mm wrench to hold the HYD-006P M10 adapter fitting in the cylinder and a 1/2 inch wrench to spin off the B-nut. Cap or plug the openings to minimize fluid loss.
3. Remove the line.
4. Cut a 51.0-inch length of hose.
5. Terminate one end of the hose with a HYD-008P B-nut fitting. (General Brake Line Termination Procedure)
6. Connect the brake line B-nuts to the parking brake valve and lower connection point on the brake master cylinder.
7. With the terminated end, wrap approximately 30 inches of each hose with spiral wrap.
8. Terminate the parking brake valve end of the hose with a HYD-008P B-nut. (General Brake Line Termination Procedure)
9. Connect the brake line B-nuts to the parking valve and lower connection point on the brake master cylinder.
10. Use a 7/16 wrench to hold the AN816-3D fitting on the forward port of the parking brake valve, then a 1/2 wrench to torque the B-nut to 120-132 in-lbs
11. Use an 11mm wrench to hold the HYD-006P M10 adapter fitting in the cylinder and a 1/2 inch wrench to torque the B-nut to 120-132 in-lbs
12. Bleed the brakes per the procedure in the Beringer Manual.
Verification Method
Verify that the line is routed correctly and the pilot’s rudder pedals move through their full travel and adjustment range freely with no brake line interference.
Check for correct operation and no leaks.
