Master Cylinder Rebuild

[Blitz1770]

The master cylinder on my 1969 Superbee is leaking pretty badly. I was originally trying to find a direct replacement for it, but because the brake lines exit from the passenger rather than driver side, there are no reproductions. So I started looking for rebuild kits, and I'm not having much luck. There are no brand names or part numbers anywhere on the master cylinder, so I have no clue what to get. Additionally, the only source I've found that might be able to supply me with a rebuild kit is The Ram Man, and I've called four times and left a message, and still haven't heard from him. Has anyone heard of an mc with no identifying markings and passenger-side brake line ports? And if so, do you know where I could get a rebuild kit or an already rebuilt replacement?

Are you trying to stick with oe style? I know wilwood MC's come with ports on either side so you just plug whatever side you're not going to use

That's a new one on me.
I'm wondering if it came like that.
Was that a power disk car from the factory?

Yes, it's factory power front disc/rear drums.

For part number, did you look underneath? Look for cast "Bendix", and probably "2226821". Date code stamped on fender side, I think 69s had been stamped.

That's actually the first place I checked. There's nothing under there at all. No Bendix logo or part number. It does look identical to Bendix master cylinders. But I was under the impression they all have identifying markings, so I wanted to figure out exactly what mc I have before ordering random parts hoping they work.

Hard to tell from the picture, but it looks like that line going to your line lock is made of copper. If so you should replace it with steel, copper lines can burst during a panic stop.

Nickel copper is being used a lot now, very strong was thinking of using it on mine.

Probably over the counter replacement. Looks either that or rebuilt with top cover/wire too (also booster). But its the right one. There's a good write-up somewhere on these forums . . .

Never heard of nickel copper tubing for brake lines. Of course there's a hell of a lot of things I've never heard of! Still, if that would be copper, get rid of it.

Wow, that's a great resource. Thanks for that. According to the previous owner, the mc was never replaced under his ownership, so it's at least 35 years old. I'm guessing it's a replacement from some defunct 70s-80s era after-sale parts supplier. But it appears to be identical to casting #2226821.

So my options are to get a Bendix mc like this one:

http://www.ebay.com/itm/MOPAR-MASTER-CYLINDER-B-BODY-DISC-BRAKES-2226821-1967-1970/251785061914?_trksid=p2047675.c100011.m1850&_trkparms=aid=222007&algo=SIC.MBE&ao=1&asc=40130&meid=bacf1155cde44d9eaa6a05e925b563bd&pid=100011&rk=1&rkt=12&sd=152524399402

Or get a rebuild kit for #2226821 like this one:

http://therammaninc.com/products/sh...REBUILD-KIT-Disc-Brakes-1967-1970-220?cid=449

I'd prefer the latter since it seems much more cost-effective. But I'm hesitant to buy from someone who I can't contact. Does anyone have any experience with The Ram Man? Is he very reliable?

Let me just say I would steer clear of Wayne.....Too many previous business issues and has clearly changed the scope of his customer service and timely delivery of communication/parts. I called a dozen times awhile back about doing a MC for me. Out of the blue months later he calls and gives me this long drawn out story. Babble and babble and more babble....I have learned that people like this are a total waste of my time and money.

However, I did find a place does does high level restorations/rebuilds on brake components.

Yeah, that's pretty unprofessional. Thanks for the heads up.

NiCopp brake line is a god-send for northern states. All I ever use at my repair shop now for probably last 5 yrs. I am very **** about routing, though, due to the softness of the line. Have had zero issues, so far ( knock on wood !! ). Would NOT recommend rebuilding a brake master cylinder at home !

There is a company called whitepost restoration. All they do is re-sleevings and rebuildings of master cylinders and wheel cylinders. You may want to try them. I have used them in the past with no issues.

Brake equipment warehouse sleeves MC's and WC's as well and uses stainless steel sleeves.......They also have a fantastic cleaning process on these cast pieces

 

[AMX364]

A rebuild with a bronze or Stainless Steel sleeve is a good long term solution. I still think someone replaced it with the wrong one in the past, but that's just me.

I have one sitting in my shed just like that. Mine came from SSBC with a disk brake conversion I did 7 years ago. I hated the snap cap and the lines being on the right side so I replaced it. I believe the conversion I used was a braking system used on a '60s Corvette or so they said. You may want to explore both SSBC and search for the GM master on line. The master was actually a Bendix. Barring that, don't order anything until you have disassembled yours and measured the internals thoroughly, then inquire with the vendor to see that you receive the correct parts. Nothing like paying for something twice. I've used nothing but Cupra-nickel (Tm) brake lines since they came out, without issue. Flare great and never leak, never rust and bend easily down to 1/2 radius without collapsing.

X2 PST! White Post Resto in VA is the best option IMO. I just had a GM MC done and they turned it around in 1 week. Fair price to restore the original piece to the car. Bled and installed, works great.

What was the cost?
