Your right Mike. The original info given when silicone fluid first came out, was that it gave a firmer pedal; now they changed that and say it is a"little spongier." I just believed their original statements. I researched it the other day, after you said it was "spongier," and saw that now they say, "spongier.!!"Damned if you do, and d*mn*d if you don't!!

Thanks everyone. I will check the master cylinder free play, as well, and will let you all know via a new thread what is discovered.

Tom may be right on track. Check the "free play" on the master cylinder.You only need a little, but if there is none, the pressure will build to the point that the brakes will actually "lock up."

A principal of physics that I learned in my junior year in High School in 1954: "When pressure is applied to a liquid in an enclosure, that pressure will be equal at all points. Thus when you put pressure on the brake fluid with the master cylinder, the pressure is equal at all four wheels, Even tho the lines are different lengths.

Steve Lee, thank you for understanding my post. 46Coupe, your problem sound like you may not have enough brake pedal free play. The master cylinder push rod must be free of pressure when the pedal is released. Please start another thread if you are still having problems.
Tom

I didn't mean to argue, I was just trying to tell people that I have a vast experience in auto mechanics. I have had a few people that actually told me that they appreciate my knowledge and comments, but your absolutely right Tom, and I apologise to you, and all. I just get annoyed when I have so much background and knowledge, and persons argue with what I tell them. Most people that ask questions on the forum, know very little about the mechanics of the automobiles that they are working on, and that's why they ask on the forum. I admit that I have asked a few, but they were to save me wasting my time and aggrevation ; such as when I asked where the coil resistor was located, how to put the convertible top down, and finding out why my volt meter wasn't showing in the green; which I fixed myself by changing the gauge.In that instance, I asked a question, even when I had an idea of the "fix", to get other opinions, which to me is a smart thing to do. Again, I aplogise to all, and will "Hold it down" in the future!"
Regards, Steve Lee

Thanks Cliftford, that's a part I had not considered as the rod seems to move its full distance. The cylinders have been shipped. I hope to have them installed by Wed. I'll let you and everyone know what happens. I could be ordering a new master cylinder if the tests fail.

Given that information, I would suspect a problem with the master cylinder not releasing pressure fully.

I have a wheel cylinder/brake issue. Possibly you all will help me here instead of starting a new thread. The history is: 46 Super Deluxe coupe, rebuilt/ and honed all wheel cylinders, installed new brake shoes, rebuilt master cylinder, replaced front brake hoses as we found the previous ones that looked new but were actually collapsing and locking the wheels. Yesterday I had a weird noise coming from the right rear wheel. Luckily I was only 100 yds from my favorite garage and pulled in to see if I could get the car on the lift. We did and a E-brake retainer fastener had failed and part of the linkage was in the drum. That we fixed. While inspecting the other wheels we found that some were locked up and some were not. Had a devil of a time getting the car in the shop and on the lift. We closed the brake shoes as far as we could and the wheels barely turned. The drums and back plates were not hot. When we finally got the drum off the right front, the left front spun freely. We put the drum back on and could hardly turn the left or right front. We had found fluid in the front cup on the right cylinder. Does the fluid some how equalize in the system? Could this be causing the brake shoes to over tighten and then loosen? I've ordered new front cylinders and will install the old shoes on the front as we think we found a hump in the center of the new shoes. Any Ideas?? By the way, I agree with Tom. I'm a novice compared to most of you all and appreciate all the help you all have/will give me. However, I've been on forums that had this issue and eventually that ended up being all it was- people being sarcastic and wasting time convincing everyone how right they were. Thanks for the comments Tom. Hopefully it ends there.
