Another weekend...
When I bought my first airplane, the person who did my checkout said to me, "Never take apart anything you're not willing to replace". I thought he was nuts.

It turned out to be one of the wisest things anyone ever told be about owning an airplane.

I spend Saturday working on the 2-33 at the soaring club. Sunday morning, I was just going to take a couple of hours and change the tires on the Tripacer. They're getting really low on tread, and I had the new ones in the hanger.

When I pulled off the right wheel, it was a pain to get off. The brake on that side was stuck 'on'. Suddenly a lot of things made sense - this is why it's been so hard to push into the hanger lately, and why Mike's been complaining about it pulling to one side on landing. So we took it apart. They're drum brakes, and they're amazingly simple - the brake handle depresses a piston that forces from fluid from the reservoir down the tubes. At the wheel, there are two pistons in a 'sleeve', and the fluid forces them out. They press against the brake pads, forcing them against the wheel. A spring returns everything back to it's original position when you release the brake handle. But it was in terrible shape - the pistons were frozen, the o-rings were hard as rocks, and there was half an inch of sludge on top of the bottom piston. I'm betting this hasn't been taken apart in 20 years.

So I'm going to overhaul the brake system. I can replace all the internals of the master cylinder, and the o-rings. The pistons would cost me $175 _each_ (I have 4, 2 on each wheel), so I'll clean them up and put them back in.

It's going to take me most of the week. I bet at the end, the brakes will work better then they ever have. I hope. If nothing else, this is yet another system that I will have taken apart and understood how it really all works.

I really do enjoy working on the plane. But sometimes it seems like it will never end...

Wow, does that bring back memories. I used to fly those suckers out of Salem, NH, before they turned the field into a fucking golf course.

The HP-18 is for sale. Don't quote me on this, but I think he wants ~14K for it.
I'll buy you a beer if you drive down here to pick it up. :)

I wish. For medical reasons my flying days are over, although if someone offers me a ride in the right-hand seat I always take it.

Always.
