The best solution is shown in this pic from Mike Parkin. A Banjo fitting. The Banjo bolt is straight threads, it lies low, out of the way of grabby things and is stoutly attached. So, I have a number of bits on order from various suppliers in an attem

After much flailing about which shall not be documented here, I went back to the double puck brake and spent a couple days trying to bleed the new system. Without much luck. I called Robby at Grove Aircraft and he pointed out that if there were any high

Here's a closeup of the hose end, bolt and washers. The hose end connector is identical to that which was on the master cylinder end so this should easily replace the 90 degree AN hose end provided. We'll know better later this week when I can get to th

The problem... The AN816 provided with the brake does not properly fit the threaded hole in the brake slave cylinder. It will screw in about two threads and that's all. You can see that the 90 degree hose end also sticks up in a big loop just waiting f

Put a bit of fluid in the reservoir and observe bubbles. Air is being pushed out and replaced by fluid. That's good. Watched this for almost an hour till the bubbles stopped and the reservoir began to fill. Shut the bleed contraption, stuff the line b

Walked down to the corner of the hanger to the next line of hangers where there is a WC. This is what I saw to the Southeast. Not looking good. Went to the WC and cleaned up. Looked even more threatening after the wash. Decided to close up and go hom

The threads on both fittings are 24/in. So that's a match. The issue is one is straight and the other pipe thread.

2010 06 06 - Made up an adaptor that fits the bleed and doesn't leak. Began to run fluid into the system. Went up to the master cylinder/reservoir to check on progress. Was I getting bubbles through the bit of fluid it put in back on the 3rd?

2010 07 08 - Back to the airport and back under the aircraft. With more aggressive abrasives, I was able to relieve the rub just a bit more. Not much at all, as you can see from the picture.

Safety wired the bolts and check the installation. Pushed the aircraft and the brake stopped it. Held the brake and tried to push it aircraft. It wouldn't budge. Very good. Pulled it out of the hanger, started it up, let it warm properly and taxi tes

Button the cowl and tidy things up. Looked out the door (West) and the weather was calm, not many 150's in the pattern. Looks like a great time to go and try it out. Filthy from the elbows to the finger tips so I have to hit the WC and clean myself bef

It took almost an hour to carefully and safely get the tap started in the aluminum brake. I sure didn't want to screw that up. Once I had a good start and the tap began to cut, I clamped the tap in the vice with the brake held high so chips fall out and

So it's back to bleeding the brakes again. Pull the lines out so there's no high spots and there's an "all up" run to the master cylinder. Connect the bleed contraption and wait.

More retraction tests. Closer, but still won't quite go into up lock. Maybe 1/4" (0.635 cm) from engaging. Back under for a couple more hours before I finally see where the blue from the fitting is rubbing on the side of the tunnel where the seat

And none too soon! This is what I hit departing the airport. We'll see what the weather is like tomorrow morning. Maybe try to fly then.
