Single reservoir Master Cylinder question

[abloch]

Picked up a master cylinder from the auto parts shop that has two outlets. Mine have only one and I was wondering if I can just plug the extra outlet before I do the swap?

1962 Dodge and it was the only option in their book. Any thoughts?

I pulled the single feed MC off and replaced it w/ a dual. Split the lines front to back and insert a prop valve for distribution. IMO, Why bet your life and someone else s on an outdated system.

X2, get rid of that single!

Keeping it as original as I can. Thanks for the advice though.

A universal master might have 2 lines but if you're trying to keep it looking as original as you can, then you have the wrong master. Does it look like this? http://www.ebay.com/itm/50s-60s-MOPAR-SINGLE-RESERVOIR-MASTER-CYLINDER-/380679790576

NAPA sells the single reservoir MC for the '62. (Are you in the US or Canada?) You have the wrong MC and you will not be successful in using a dual with a plugged outlet; you can't get all the air out for starters, and even if you could, then : If the front is plugged that section can't move, and the other section cannot move the full range needed to close off the inlet port. It won't work with the front port plugged. If you are determined to try, plug the back port and try the front; but you can't get all the air out of the back section so it wil be soft or unusable.

Just my view if you don't mind reading on: I have a '62. Mine is 99% original and I even just got an original Carter fuel pump to put on for originalilty. BUT, the one thing I will not do is ride around on a single master cylinder; I did it when young but no more. You need to understand that if you have 1 small leak anywhere, then you will lose ALL your brakes. You will be kicking yourself in the *** if you crash because you did not do this. I did this change 1st thing on my '62.

Please reconsider if this is a driver car; for only a towed show car, then OK. For a driver, you are adding risk for the life and health of you and your passengers with no seat belts and the old brain-basher metal dash, and to make that worse with a single master cylinder makes poor sense. The change is simple: Use a '67 Coronet dual and get the conversion kit from Inline Tube in MI. It'll bolt right in.(And I am assuming manual brakes with a 1" MC cylinder diameter.)

You can always put a single back on for show only.

Sounds like you got one like I did...single reservoir with an outlet out the front and an outlet out the bottom. Mine came with a brass plug to close off the one I didn't use. Yours should have come with a brass plug as well.

I believe those with two outlets were used when they used a hydraulic stop lite switch. I bought mine from Rock Auto (was a Raybestos)

Keeping it original and risking your safety ?

There's a reason that the single reservoir was replaced with a dual reservoir - a single reservoir has a single point of failure - any place in the brake system leaks and you've got no brakes in the car. A dual gives you (2) points of failure by separating the fronts from the back brakes.

It's your car - I'll always support doing it how YOU want,

just wonder if you'd considered the safety aspect and the reason why no car makers use a single reservoir anymore . . . I don't drive a car unless it has a dual master.

Good luck !
