|
I made a 'bottle' out of 2" PVC. Pipe plug in one end to fill with, cap
on the other. Two holes below the pipe plug end. Plastic hose through
one hole down to the bottom where the cap is and the other end goes on
the bleed fitting. My air gun goes into the other hole. Bleeds almost
any brake system quickly!
Linn ..... got hand cramps from pumping that oil can!!!

I've had mixed results with the pump-can bleeder but we still use one
in the field. I think the problem is that without sufficient flow,
you can still trap bubbles at the top of an arced tube. The fluid
just flows under the bubble.
For the shop, we built a brake bleeder out of a power steering pump.
We turn it with a drill motor. Added a return like John said, a
reservoir and a little plumbing. It works like a champ at about 20-30
psi.

>> No seal replacement required. Remember 83282 is 100% compatible with 5606. If you want a slightly more durable seal you can go from MS seals to Viton. Don't know any reason to, other than it probably resists high temp better while is less flexible at low temps. If your mission is between ElK Mound and International Falls year round you probably want the standard 5606 and MS seals.

>> All depends on how much effort you want to do, and what your normal mission profile is. Those that get OHare and Hartsfield taxi routes probably want the higher temps, like those of us on the southern fringe of the country.
>> Do you want to go into procurement mode, get the fluid, get Viton O-rings after figuring out exact size needed, and so on, just like the rest of the build process? The mechanical work on the calipers is child's play. Draining your system should get you 90 percent of benefit, vs flushing system and then adding 83282. You get the fun of bleeding the system either way.
