Ever see ad for clunky little gadgets that slip on like eye glasses? There are two little lights at the temples. Years ago I got one. Not wonderful, but they did help a couple times when had to do some night harvestings. The problem was wearing "specs" at the same time. Think I like the headlamp idea much better.

I copied this from Wikipedia (I think) - even their condensed explanation is too much to say the least. Presumably it can be removed. Microsoft initially shipped Windows CardSpace with the .NET Framework 3.0, which runs on Windows XP, Windows Server 2003, and Windows Vista. It is installed by default on Windows Vista and is available as a free download for XP and Server 2003 via Windows Update. An updated version of CardSpace shipped with the .NET Framework 3.5.

Hi all! The long-awaited response -- my contractor came over the following week and I explained what I found online wrt Newton's Rings, and his eyes began to glaze over. Now he thinks I'm a nutter! Nonetheless, he called up the window company, explained the situation, and they said that this was not an unusual thing and that they fix this issue often. They came by and checked it out. They said that this happened because they installed the glass when it was cold outside and that the windows would clear up when the weather became warmer when the gas expanded back to warm-weather conditions. I totally agreed, but asked him if it would recur when the weather in CANADA got COLD again, say, for six months of the year?! Result -- they popped the triple-glazed panels out, and injected gas to equalize the pressure betweeen the panes. They sealed up the windows and popped them back into the frames. Voila, no more Newton's Rings. I will keep an eye on the situation, and if they do recur (hopefully in the shape of the Virgin Mary for eBay sales...) we will address it again. Thanks so much for the BEST. INFO. EVER. Maya

As you know, you have a brake failure. The brakes must be renewed before this vehicle can be driven again. Something blew out causing loss of brake fluid and no brakes on the affected wheel(s). Your vehicle likely has a split brake system and you've lost half of your brakes, else you'd have no stopping power at all. Maybe the hand/parking brake would yet work. The '96 Tahoe, in standard form, has shoe brakes on the rear wheels, and I assume that is what you have. The failure could be a broken or leaky brake line/fitting or it may be the piston/seal in the wheel cylinder. By your description, I vote for the latter. As the brake shoes wear away, the piston in the wheel cylinder moves farther out. If the brake drum has been over machined, the piston can come out too far and fail. [I had the same thing happen on a 1986 Chevy Citation. The piston moved too far out, tipped, and spilled. In my case, it was my opinion there was a design flaw - the brake cylinder was too short. After the brakes were rebuilt by a brake shop, I noticed that the repair cylinder was longer than the original.] Whatever the case, I suspect you have a failure at the cylinder. You'll need to pull the wheel and brake drum to see what failed. Until then, we are guessing. Let us know what you find. Measure the brake drums to see if they are within specifications. If the drums are over the wear limit, new drums will be needed for the rebuild. Do a google search on "96 tahoe brakes" and you'll find there has been more than an ordinary amount of problems with those brakes.
