And he now has a leak in the rear of the master cylinder. I thought i used raybestos 36283 .....BUT. that number the lines exit fenderwell side. The one on the car exits engine side. And i no longer am able to get into old pc files to look it up

I don’t think they’re available anymore. I guess you either use a 36283 and reconnoiter the lines, or rebuild what you have. To further complication matter afaik after market MC kits are not available anymore. So either look for NORS or buy a 36283 and pirate the piston assemblies to rebuild the old MC.

Ive passed said info along. And I think he is going to just buy a 36283 and buy new master cyl lines and move them to the fender side and call it done

Why not buy a good rebuild kit and fix that one I would Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

OHIO, USA	Bill I looked through a lot of photos of '68 B-bodies with power brakes, not sure if any, some or all were disc or drums but one thing that stuck out (pun in a moment) was ALL of the brake lines exited on the engine side of the master cylinders. Then it hit me why they might be on the engine side. The power brake booster moves the master cylinder forward and this puts the brake lines right over the top of the shock and hinders the fender side brake line master cylinders from exiting and going straight down to the proportioning valve. Seems to me this may be the reason for the exit on the engine side on power boosted brakes??? I know my '69 GTX with power disc brakes has the brake lines exit on the engine side and I remember someone saying that was correct for power brakes, drums and discs. Now I see why with the forward location of the master cylinder over the shock inner fender. Mike

This is what I have found. I bought a couple of spare ones back then. The only ones I’ve been able to buy lately are the fender side exit lines. The factory used engine side exit masters cly on wedge head cars and fender side exit on hemi engine cars. There has been many wedge head cars found with fender side exit masters, though,especially on Superbirds. The master cly shown in the above post are an aftermarket casting made with the ability for machining the lines for either side. Mopar never made one like that.

Here is a '67 GTX with a 440 and power front discs. "We live in a time when intelligent people are being silenced so that stupid people won't be offended".

The second image is how it was when I bought the car from the original owner. I'll check when I get a chance later for the part number. Mike

A12 Too Many Posts Joined: Jan 2003 Posts: 21,505 N.E. OHIO, USA	Bill the casting number on my original '69 disc brake master cylinder is 2226821 and is listed for '67 -'69 B-body with disc brakes. It looks pretty much like the one in your photo and the 2223821 master cylinders are difficult to find even used. If he's not concerned about "numbers" find a suitable replacement (reman) and sell that one for decent $$$ if it is a 2226821. Personally, I would see about having it professionally rebuilt, again if it is a 2226821 master cylinder.

At least i dont remember it being one Owner is going to pull it off this week and see if these casting numbers are in it. If thats the case....he may try and rebuild or have it rebuilt Edit....owner found an nos one. Turns out the one on the car was indeed an original. Guessing a Reman unit i came up with. So it will go in the spares bin. He wants to find a kit and hang on to it Just in case

Took the GTX out Saturday and I know I filled or topped off the main reservoir (low a few month ago) and then Sunday just out of curiosity I checked it and it was almost dry. I check the garage floor, all of the brake lines and all of the wheels and don't see any sign of brake fluid so I'm guessing it's leaking into the vacuum booster from the first master cylinder seal if that's possible? Going to pull the master cylinder and will probably need to rebuild it if parts are available or find a 2226281 casting Bendix master cylinder but would rather try to rebuild this one as it is the original to the car. All the info says it's an 1-1/8" bore. I could maybe find something that works for now and hopefully find some place reliable to rebuild and return my original? Any recommendations would be greatly appreciated, thanks. Mike

Orig and orig replacements were 1 1/18" bore. Below is the data on mc. C body used theses too. The difference was pistons installed. Though you probably would not notice any difference. These are all Bendix units. 2881868 MC Casting 2225621 to Fender 67 All B Body and 68 B with Hemi 4 Piston Bendix 2881870 MC Casting 2226811 to Fender 67-68 C Body Fat and Tall 4 Piston Budd 2883058 MC Casting 2226821 to Engine 68-69 B Body without Hemi 4 Piston Bendix #1 2944269 MC Casting 2226821 to Engine 68-69 B Body Station Wagon Power Drum #2 2944376 MC Casting 2225621 to Engine 69 B Body with Hemi 4 Piston Bendix #3 2883089 MC Casting 2225621 to Fender 69-70 C Body Floating Single Piston Calipers 2944476 MC Casting 2229191 to Fender 70-71 B/E Body with Hemi Fat and Short #4 2944477 MC Casting 2226821 to Engine 70 B Body without Hemi Floating KH Single Piston Caliper #5 2944479 MC Casting 2225621 to Fender 70 B Body Taxi Manual Disc has studs

I would need a rebuild kit for: 2883058 MC Casting 2226821 to Engine 68-69 B Body without Hemi 4 Piston Bendix ('69 GTX 440, front power disc brakes) There are a few listed on eBay but until I take my MC off and apart I don't know what I need to start looking for. On the other hand, I will need to take it apart first to confirm what I need, (duh) but a rebuild kit part number may get me into the right area to search. Thanks, Mike
