Master cylinder puking fluid

-
That master cyl on summit is not the way to go.It has a "sloped" reservoir.This is not the one you want.Plus the entire set-up with the handling charge is over $150.00.

This is what you want.
E-bay item # 280061064776

Little over a day on the auction,but this seller has them all the time.
$100.00 for the complete set-up with a NEW master,and the correct Mopar adapter.

I bought this MC from this seller and have it on my 65.

Krabysniper,

Black silicone,jb-weld....Bad idea.Brake fluid will eat anything,including black silicone & jb-weld.
If you were to get silicon in your brake system you would have more problems then you have now.

wasn't sure about the JB Weld, but I'm pretty sure that the silicone would swell up eventually,lose contact and start polluting the brake system as you mentioned.

I would probably take it back off and clean it up real good and fill the rust spot up by building it up by welding (with a welder) and grinding it back smooth...just another idea...
 
You could probably take it off and resurface it with a hand file, or on a surface grinder at a machine shop,if their is not to muchof a suface differnce.
I did mine on my 67 F.B. with a file, just make sure you kleen it out real good and get all the filings out.

You and 340_Scamp are both wrong. I don't mince words so don't take offense, but brake fluid does not, nor did it "eat thru anything" nor did it disolve, soften or in any way affect the silicone. Yes, it is good at ruining paint, of that we ALL know, but as far as it dissolving the silicone, nope. My repair lasted thru the fall till I put the car away, I also made certain not to put so much on there that it was spooging into the reservoir side, JUST enough to seal the edge of the MC along the edge's where it was pitted. I also know for fact that JB Weld will stand up to brake fluid just fine, tested my theory first (as I did with the silicone) by putting a lump of cured JB into a jar of brake fluid, and letting it sit there. Wanna know what happened to it?? Nothing, just a chunk of JB sitting their doing nothing. Still as solid as when I dropped it in. I apreciate the input, don't get me wrong, just letting you know that you are very mistaken in your assumptions. :headbang:

Cudasrule (no they don't, but thats just my opinion, LOL) No, the cap seal was brand new and was fine, it was the edge of the master cylinder that the seal was SUPPOSED to seal against, pitted like you would not believe, if it hadn't have been for how cheap it was in the first place (I think I paid less than $20) I would have taken it back and jammed it up someones crapper, but as it stands I was able to solve the problem myself and save myself the headache of taking it off and replacing it AGAIN. I hate doing that with anything.

As far as welding on a cast master cylinder housing 340_Scamp, you most obviously are not a welder. That would be a really BAD BAD thing to do to it. I am/have/was a welder by trade, you cannot weld on thing cast steel and expect it to hold up, or not warp, let alone the fact that the heat would destroy the seals in the MC putting me right back to square one, and the risk of getting weld spatter inside is high and one tiny grain of spatter would be just as bad if not worse than a chunk of silicone floating around in there.

No, I will stick with my repair. I am happy with it, it works, no more leaking brake fluid and the car will eject you thru the windshield if I stomp on the brakes and your not wearing a seat belt. Good enough for me.

I do wish to thank EVERYONE for their input, right, wrong or indiffrent, it was all very helpful in the search for a solid working answer to the problem. :happy4:
 
Dam brother,
Asking people for help and then telling them your mistaken,you most obviously are not a welder etc etc is not the way to treat people who are trying to help.

If you think fixing your Master Cylinder with silicone sealer is the proper fix and your happy with it,well then more power to you.

Remember it is not what you say,it is how you say it.
 
I am not your brother.

I made it quite clear, I DO NOT MINCE WORDS, you were wrong. Period. If your going to make a post stating that something will happen a given way if you do that something, then I would suggest you know what you are talking about first. I tested whether the brake fluid would have any affect on the above mentioned repair techniques before doing them. I merly let you know that you were wrong, thus letting anyone else who may run across this thread in a search in the future, due to the same problem, to know what will work and not be mislead by peoples assumptions or guess's. It was obvious to me that your thoughts were not based on fact but on what you thought MIGHT happen. Had you taken the time to test the idea first you would have saved yourself the time of posting something and then being told you were wrong.

I thanked all who had ideas, whether what they had to say was legit or not, you seem to have issue with the fact that you were wrong and I pointed it out, for all to see. Guess what, thats not my problem.

Letting people know truth is not wrong, leting people believe someting is right when it isn't, IS WRONG.

To your last comment, there is no "HOW YOU SAY IT" here, I am not SAYING anything, I am typing and you are reading type on a web page. I feel for you being informed that you were mistaken. It happens. I can't sugar coat reality just so you can feel good, and I certainly cannot place any TONE or FACIAL EXPRESSIONS or BODY LANGAUGE here with this type, for you to infer that I was not tryin to be mean but merely trying to share info so future readers and yourself would have facts, not just guess's or assumptions.

My fix worked, and damn well thank you. I am not typing that you have to go out and try it or do it to your car, I am letting anyone in the future know that it can work and save some headache for them if they wish to try it. Would it have made you feel better if I had said "you were mistaken"? Would have meant the same thing, but if it makes you happier, you were mistaken. :thumbup:
