brake line repair

Post by Sweetnam »

Developed a brake fluid leak on my 170b Cleveland Brakes at the place where the starboard steel line is clipped to the strut. My mechanic, who is only marginally familiar with the 170, pulled the steel line down the strut but reports that he is having trouble finding "the fitting to the rubber hose that goes into the brakes." Can any one advise?

Is your “mechanic” an actual A&P/aircraft mechanic?

The metal line which runs down the landing gear is usually aluminum not steel, although anything is possible on these 70-yr old airframes.
Aircraft Spruce or Genuine Aircraft hardware suppliers should be able to provide the proper fittings. Do you have a pic you can post?

Is this what he is needing?: https://www.aircraftspruce.com/catalog/ ... kkey=10357

Thanks for your quick reply. Yes, he's an AP but mostly works on the commercial planes over at Bradley. I'm the one that assumed the lines were steel. I'll forward this information to him. Thanks again.

If he’s been working on large aircraft…Be Certain he knows that the brake fluid in a Cessna 170 is Mil-Spec-H-5606…NOT what is in most larger aircraft.

I'll make sure he knows about the mil spec H 5606. I just checked at the hangar (his own shop is down at Danielson Airport, a few miles away,) and he took the whole lower rubber hose and fittings so I assume he'll replace what he needs to connect to the new Al brake line. Thanks for your advice.
