WTB - 63-64 FC/EM master Cylinder
Posted by: SteveInMarietta ()
Date: March 18, 2017 07:16PM

After a couple of false starts (and ebay return), I've decided I need an original 1963-64 FC master cylinder for the Firebrier - with a snap-on not screw-on cover. I believe the MC from the same year cars are the same. Does anyone have a good quality, restorable one available?
Thanks,
Steve

You want a core?

New ones are available just about everywhere. Rebuilts are relatively inexpensive.

Marco,
The new ones are different; indeed, the new one I'm trying to return through ebay is different enough to be unusable (and didn't match the description). Clarks notes the difference in their catalog. I haven't seen a rebuild of a bona fide original one anywhere yet, but maybe I've overlooked these, and please point me in that direction if you can.
Thanks,
Steve

1961-63 FC had a square M/C with screw-in in lid.

1962-63 cars had a cap with a thumbscrew retainer (in the center).

1964-66 cars had a lid with a "snap-on" wire retainer.

Is this what you are looking for?
You say with the snap top not a screw top?

That Duralast is very likely Chinese made. I bought one of these (Chinese) and the cap and the bail (cap retainer) were not very well formed,
but I worked them over to be acceptable. If you were to substitute the American made parts (cap and bail) you would be more happy with the setup IMO.

Although the above picture does not show the back side of this new MS, all of the other similar offerings I have seen online are different than the original as shown below. It appears they are manufactured to accept the brake line either from the rear or the side, with the unused port plugged with a set screw.

The Duralast one I have looks just like the picture you posted. Also has the rubber boot for the actuating rod.

So what you are after is a MC with just the side port and no bleeder valve?
Correct? You want a rebuildable core?

Marco,
The MC in the Firebrier is not original (it is old as the ages, but has a snap cap & a bleeder valve), so I don't know for sure what was there originally. However, the Firebrier is a late '63 build and has the larger size opening for the MC floor plug, and I suspect that that redesign was introduced when the MC was switched from the screw-top cover to the snap-on cover (so yes, that's why I'm looking for a rebuildable core you described). But maybe I'm wrong. Thoughts? By the way, do all FC MCs use the same rod?

Al,
Thanks for the offer, but I'm not sure that the LM MC is correct for the FC, and they look pretty rough. I was told once that a critical issue is the condition of the piston bore - if it's corroded, the MC is shot.

Thought one of them might be the same as you are looking for. I thought maybe the top 2 might be rebuildable.

It just might be time to toss them in the scrap metal pile and send them to china.

Steve:

Parts catalog states the following:

Item 4.650

62 - 66 CORVAIR. F.C . . . . 5465489 (1 die, cyl.) Moraine

So 3 of those I have would be OEM for your Firebrier.

The car master cylinder bolts right on with no problem. Unfortunately the wire bail is difficult to remove on an FC. You have to crawl under the vehicle to snap it loose. Also the late car cap won't go thru the access hole in the floor so you have to remove from underneath. the original FC cylinder had a small iron plug that does come up thru the hole.

I will maybe take the cylinders out and find the one best bore. Keep the best one for the Corsa. But that is a maybe. Haven't determined if I will stay with single master. That decision is down the road after engine is running.

But since the single is available from FLAPS, no need to keep junk.

A tricky issue with parts catalogs is that in later years, as parts are discontinued, the current acceptable part number would be substituted. So, for example, 5465489 is listed for all Corvairs in some later date P&A catalogs, but the 1964 P&A 34 catalog shows 5464735. How do -5489 and -4735 differ? - Beats me. To make matters even more complicated, the part number for the MC in the 64 car and FC assembly manuals (5465094) is not listed in the P&A catalogs (but looks like the ones in Al's pictures).

The MC lid fits through the larger size floor panel hole, but not with enough room to hold the edges with your fingers. The FC MC with the 1" plug was discontinued in mid-62, I believe.

There is a shop called White Post back east that places a stainless steel liner in brake cylinders. If you find the correct part it can be rebuilt.
