Narrative:

Customer reported left brake assembly leaking fluid. Found broken flare on hydraulic line at the brake housing; also line was slightly crushed at b-nut at the brake housing. Fabricated new line following contour of original line with slightly larger bend radius to prevent crushing line at brake housing. Customer picked up airplane and few to his home base in ZZZ. The next day we received a phone call stating the left main landing gear had stuck in the gear well due to the new brake line. The pilot managed to free the main gear; and made an uneventful landing.fabricated second new line; this time performed gear retraction test on left main gear; found 90-degree fitting on brake housing turned allowing b-nut on hydraulic line to rub and catch on sheetmetal structure in wheelwell. This structure was used to cover the landing gear door actuators. Turned brake fitting tighter; allowed b-nut to clear all structure and allowed gear to move in and out of the gear-well freely. This area is very tight and all lines and fittings must be positioned exactly. Performing a landing gear retraction test would not normally be done for a brake line change; but I will be doing one from now on; and nothing is mentioned in the [cessna]maintenance manual for a retraction test.
