New Brake Install

[NunavutPA-12]

My PA-12 has (almost) always been on floats. It does have the brake boosters installed, though.

Since I'll be changing over from floats to wheel-skis and back every year, I understand that the best way to install the brake lines is to use a short piece of aluminum or copper line from the boosters to a couple of bulkhead fittings on the (metal) belly. Then I can use my existing hose from the bulkhead fittings to the brakes. Is that the best way to do it?

Like this.

The blue cap behind the gear fitting is the brake connection.

Sorry, I should have mentioned that my PA-12 is Exp. so I don't have a fitting as in your photo, but that would work. Thanks.

The plane in the picture is experimental also. The fitting is a 90 degree which is connected to the master cylinder with a hard line routed under the floor.
This is what it looks like above the floor. You can just make out the hard tubing as it goes under the floor just outboard of the master cylinders.

Perfect. Thanks for the photos.

The "hard tubing" you refer to ....is that aluminum? I'm having some difficulty finding hard tubing is the Aircraft Spruce catalog. I see "3003-0 Versatube" billed as "soft aluminum tubing" (p. 54). Is that the stuff to use?

Yes aluminum. http://www.aircraftspruce.com/catalog/mepages/alumtube_5052.php?clickkey=226040

03-39300 You could use 1/4" copper if it is more ​

available. You could also use 3/16" if you wish. It would be adequate.

I can't figure out why the computer is screwing up this message.​

Great! Thanks for that. Sorry to have to ask so many dumb questions!

No question is dumb if you don't know the answer.

Where is Nunavut? I have been to Inuvik, Tucktoyaktuk and Wood bay in the NW territories. It was a wonderful experience flying around in the north land. The wind shifted in the night so I had to get out quickly to avoid being stuck for an extended period.

Nunavut is a new territory, carved out of the eastern part of the Northwest Territories. 708,000 sq. miles - even bigger than Alaska (but fewer Super Cubs and we're not as smart!). My place is about 375-miles north of Yellowknife. Drop in sometime :smile:

Kugluktuk?

 

[NunavutPA-12]

Yup.

In my younger days I would have. My adventures in the far north are over even though I still have the flying machine.
