Brake reservoir leaking at the bottom edge
I brought my car into a repair shop to be inspected and the mechanic said I had a brake fluid leak which appears to be coming from the bottom edge of the reservoir. I had noticed this about a year ago and asked FFR to send me another one. Now I have the same problem so there must be more to this. I was thinking that the reservoir had a weld on the bottom of it that was leaking. I took out the "old" one and looked it over closely. What I discovered was that the reservoir is actually made up of two cylinder cups. Look into the reservoir and you can see the top of the smaller cup at the bottom of the outside larger cup. They must be pressed together to form the reservoir. So how was the brake fluid getting past the top of the inner cup between the two cups. Only thing that could cause that is pressure.
Well the cap of the reservoir has a hole in it so any pressure in the cup should escape through the hole in the cap. That's the way it should have worked. As the fluid heated up in the lines and brake cylinder it would expand causing the the pressure buildup. Also if the fluid level was too much it wouldn't give it enough space to expand. Well I took a vacuum pump and connected it to the bottom of the old reservoir and pumped it up. I expected it to not hold any vacuum. It reached 10 inches and held it there for over a few minutes. That should have not happened according to my thinking. I tried to blow through the hole in the cap and nothing. I drilled a very small hole into it and still couldn't get any air through it. It wasn't until I got the black gasket out of the cap that it worked. I couldn't find any hole in the gasket so I put one in it. So that should take care of the leaking reservoir. Just don't overfill it and don't over tighten the cap.
I have been chasing my tail trying to solve a random problem with my steering where it will slightly pull to one side or the other. The "crowned road" effect. I had the alignment double checked and it was still good. Now, with what I just explained above, I was wondering if that might be causing the problem. With enough pressure I had in the reservoir to cause the fluid to pass between the two cups, was it possible that it was causing excessive pressure in the brake system causing the calipers to not release completely, causing the pulling on the rotor on a wheel?
I will test drive it after I return from the 4th of July week end.
700R4 transmission converter lockup
Months ago I was under my car installing a shifter and I was having a problem with the linkage passing on the left side of the transmission. There was a plug there with a vacuum switch in the way. I ordered from BluePrint the engine and transmission combo so I didn't know all that I had. A call to TCI and I found out it was for the converter lockup. Wow, something extra that I didn't know that I had. I asked how to hook it up and it was as simple as adding a switch and a vacuum line. I did all that and it worked nicely. It reduced the rpm in 4th gear by about 500 to 700 rpm. Better fuel economy, GREAT! There was one drawback. I had to turn the switch on and off to use it and prevent the lugging when I reduced the speed.
I found out there are controllers available that would control the turning on and off of the lockup. Problem was that most of them used the speedometer cable that comes out the side of the transmission. As you know there isn't room for that in our cars. So I thought about using the GPS that goes to the speedometer. The AutoMeter speedometer controller uses pulses from the GPS unit to tell how fast you were going. And with the way you had to "calibrate" it was not a way I wanted to go. I fly Quad copters that use GPS to know where it's going. I had a few GPS units hanging around. So I decided to use them and a computer module and a relay to determine the speed and to turn on and off the converter lockup with the relay in series with the switch. I have a background in electronics, computer repair and 20 years of computer programming before I retried. I programmed my control unit to turn on the lockup at 45 mph and turn it off when the speed dropped below 40 mph. Works like a charm. Now I don't have to worry about when to turn the lockup on and off. It feels like another gear in the transmission. I liked the way it worked out and giving me a little bit better fuel millage.
I was thinking that other people would be in the same boat as I was in and had a need for one of these controllers. I might build a few and sell them on Ebay. Well I checked in Summitracing.com and JEGS.com and they sell something that is similar, using a pressure gauge to determine it's in 4th gear and all that. I don't know if I would sell them. I might make a couple and see if anyone here would like to try it out and give me feed back on what they thought about it. Sort of a test group. I'll see.

'33 Window channel guide installing problem
In the new instructions for the electric windows they have added a new piece. See below. This piece is to guide the right side of the window so it exits the slot in the door for it. I am having trouble mounting that new piece. I had to cut away on the inside of the door and I'm thinking, before I do any further cutting, I should see how other people are dealing with this new piece. Post pictures if you can. Thanks ...Cliff
