Correct power booster check valve? 69 B-body disc

Just 6T9 CHGR · January 26, 2007, 06:37:51 PM

Anyone have a pic of the "correct" power brake booster check valve for a 69 B body with discs?
This would be for the crimped style Bendix power booster.
Should it have 1 nipple or 2? Color?

Chatt69chgr · January 26, 2007, 10:06:59 PM

I don't have a pic but am interested in knowing the answer to this. I looked up the brake check valve on rockauto for both a 69 charger and a 69 New Yorker (both used the Bendix crimped dual diaphram booster). They list two Raybestos Part Numbers. One is a CV89005 which was for the charger. It has one nipple coming out the top of the valve and one out the side. The New Yorker listed a CV89004 with one nipple coming out the side and the other coming out the other side (opposite 180 degrees). They appear to be made of white or off-white plastic and come with grommet and plug if you don't need one of the nipples. Didn't the charger have one line running from the check valve to the vacuum fitting on the manifold and another line running from the other nipple to the vacuum canister? My car didn't originally come with a booster but I am retrofitting one so this is why I am interested. Oh, there is a check valve and grommet package for Bendix power brake booster listed on the long list of so called "NOS" parts that has appeared on this site in the past. It is a 3420973 superseded to 4271382. The last number is still active and lists for about $15. I don't know what this part really is as the Dodge sites don't have pictures nor do I know if it has one nipple or two or the orientation of the nipples. Anyway, someone will post a picture and that will solve the mystery. Thanks.

Chris, my car has the check valve that has the off white color and has the nipples 180 degrees from each other. This was what was on my car when I got it as it was coded for power disc brakes from the factory. When I had my power brake booster rebuilt, they installed a new one that was exactly the same and the company said it was correct for disc equipped cars. Knowing how Mopar changed vendors frequently, anything is possible and it could have also been plant specific.

You also might want to check with MoparJohn as his car is a factory disc brake car and was built 3 days prior to my car to see what kind of check valve his car has also.

Just 6T9 CHGR · January 27, 2007, 06:45:22 AM

I am definately getting conflicting reports....some say 1 nipple, some say 2. I have seen 440 & Hemi cars with both (Hemi cars mostly with a white 90º single nipple style)

The cars that I have seen with 2 nipples in use were the cars with cruise control. Non cruise cars with the 2 nipples had one blocked off. The vac line for the can always went to the manifold

Also some are saying that the valve should be painted black along with the booster/master assy

resq302 · January 27, 2007, 07:48:39 AM

Chris,

I just dug out the factory repair manual and checked some of the pictures in there. The show the check valve with the one line going to the vacuum on the engine going into the large flat surface of the check valve with a smaller nipple at a 90 degree angle to the one from the engine. This is on the picture with a Bendix style booser and disc brake m/c. (page 5-23 of the repair manual)

Now to confuse matters worse, below the above picture, they have a diagram for a Bendix power brake assembly drum and disc brakes with the drum m/c shown. (I was always led to believe that if you got power drum brakes, you got a Midland Ross type booster) That booster is the same as the booster above but has only 1 nipple and vacuum line going to it with no other nipple shown. Yet where the vacuum line attaches to the engine only has a vacuum port with 1 nipple going into the intake manifold.

Looking at the lubrication and maintenance section on page 0-15 and 0-16 they show even more conflicting info as they show a Midland Ross style booster with a disc brake master cyl. on a 318 engine, yet it has an unsilenced air cleaner. The m/c also appears to be a hemi style as the lines exit out towards the fender, not towards the engine. The m/c is also painted black yet the booster is a lighter color, probably the gold cad like the Midland Ross units were.

I guess it all boils down to they installed what they had at the time your car came down the line.

Chris,

FWIW...the vacuum fitting MAY be model/ application specific or possibly PNs were superceeded during the year. I did a quick scan of the 69 BS I have.

It appears that 69 Chargers B41/B51 recieved the '66' valve. But I also show the 66 was used on a B31/B51 and a B51 only car.

I also show for Chargers:

'38' for a B51 car and a B31/B51 car
'86' for manual as well as a B31 car
'25' also for a manual car.
I show '31' for two Charger 500's B41/B51 Hemi cars.

The only Charger application number that shows up for other 69 B bodies is '66' application for a B41/B51 Hemi GTX. The rest of the B bodies have different numbers.

I only cross referenced by B code and VAC FIT. I can look at it my sheet more in depth if you want me to.

This may be a partial answer to the paint question. If there were that many different vacuum fitting applications for the same brake set up, the brake assembly person would not know what specific application the booster/MC was going into so how would they know what check valve to install before painting? Wouldn't it make more sense to paint a more general application (the booster and MC) and have the unpainted valve installed later on the line?

resq302 · January 27, 2007, 10:56:52 AM

Do you have a picture of what the "66" valve looks like? Or does it look like the one in the pic below? (that is what mine looks like)

I dont know. That was just a picture I had saved to use as a reference in case I ever needed a new part that I would have the part number to compare it to or to try to order through a local Dodge dealer.

Chatt69chgr · January 27, 2007, 12:20:13 PM

I looked up the 3420129 on mymopar and it says it's the check valve for most 69-71 Bendix boosters. Tried looking it up to see if you could buy one and can't find it on any of the Mopar sites I have for buying new parts. Must not be available from MOPAR anymore. If someone has better resources, I would like to know if it is available and if so, what the Mopar number is if it has been superceded as well as the price. If it isn't available anymore, the Raybestos CV89004 looks to be more or less the same thing.

69fuchs · January 27, 2007, 03:40:59 PM

This is the valve that has been on all of my pdb 1969 chargers. (I have had 3 original cars) Someone was reproducing them for a while, but they were stupid expensive (like $100.00)

Just 6T9 CHGR · January 27, 2007, 06:20:36 PM

Thanks for all the help guys. I agree this a confusing stuff!

I was looking in the 69 parts manual and it seems that the correct # for a power disc brake car the # is 3004626 which a few of the "collector" dealers still have ...they want $60 & up for these. It seems as though they are a dual nipple design with 1 pointing striaght up & the other off to the side 90º
Much like the above pic

I think for now I will grab the $8 Raybestos one & call it a day.....now should it be painted black with the rest of the booster

Shakey · January 27, 2007, 06:43:20 PM

I was told it should be painted black.

Just 6T9 CHGR · January 27, 2007, 07:23:08 PM

Back N Black · January 28, 2007, 10:48:33 PM

This is the check valve on mine,just bought the booster on Saturday from UAP/NAPA.I guess these guys can still get the check valve?

resq302 · January 28, 2007, 10:58:17 PM

Looks like that check valve has one extra fitting on it though. Also, the booster doesnt look like an original Bendix unit. Didn't the originals have recessed areas on it?

8WHEELER · January 29, 2007, 06:11:27 AM

Those are pretty much all anybody out there sells these days. I don't like
looking at a check valve that has three ports plugged, so I just use the one
port valve, but try and find one, if you can let me know.

The top picture is what I prefer, the bottom pic seems to be the way most of them are,
so I am thinking it might be correct

Just 6T9 CHGR · January 29, 2007, 09:09:24 AM

This is the Cardone booster I got that is made of unobtanium........searched for almost a month for it and the correct master.....

It has this valve on it

Now another question to ponder........is there supposed to be a gasket between the master & the booster?

Brian this is a drum brake ck valve I believe.I have one here in stock

Booster and valve are both painted gloss black as an assy.

I'll have to dig thru my pics and see if I have any of a 1969 survivor disc brake car .

By todays paint standards, Yes it will be a low gloss black. In 1969 it was just plain old TX9 paint

resq302 · January 29, 2007, 09:00:24 PM

Ok, so the entire assembly was painted with the master cyl bolted to the booster. I guess I need to paint the 4 nuts that hold the m/c to the booster then and find a correct check valve.

Just 6T9 CHGR · January 29, 2007, 09:03:54 PM

This is the one I just ordered from Rock Auto for $6

on the 69's the caliper bolted directly to the spindle and did not use any adapter plate like in your picture. Also, the backing plates were rounded and not squared off where they met the caliper area.

resq302 · January 30, 2007, 12:15:56 PM

I asked Chris the same thing since they seem to be so hard to find, I was going to try and pick up on as a spare for me. I went onto Rockauto.com to see if they even had any there. No luck. The only rebuild and restore yours that you send to them. Supposedly they do repro the boosters but I have not seen what they look like. The thing is once you find the booster, you still need to get the linkage for it.

rare69 · January 30, 2007, 12:38:07 PM

i have the linkage and master cylinder just need the booster. and since my car was drum brake car not disc and i am using willwood front discs my booster wont work even if i had it restored.

Just 6T9 CHGR · January 30, 2007, 12:41:45 PM

The Cardone # is 54-73603. It took me a month of searching online to see who had one. Found one out in CA.

MBM Brakes out of Asheville, NC is supposed to be repoping the Bendix dual diaphram booster. Their retail outlet is Pirate Jack I think---also in Asheville. I believe you can google them up. I've been checking with them since last April on the booster. Not sure what the release date is now but last time I called it was supposed to be this spring. They have really good stuff and I think that eventually they will have this part. Maybe more folks ought to call them and talk to a sales guy and bug them. Don't just talk to the nice lady that answers the phone. They say they will tell the sales guy but you know thats bull. I will say that every time I have talked to these guys they have been very curteous and as honest as they could be. So be nice to them.

Lord Warlock · February 01, 2007, 03:54:23 AM

I suppose i could lift my hood and take a picture of mine, I replaced my disc brake booster back in 1982, so it may or may not have the original check valve in it. I seem to remember that when i replaced the booster the check valve I kept was the original, and I do believe there was a gasket to hold it in the booster (wouldn't fit tight otherwise)

In case someone is desperate for bendix calipers, i do have a spare set of them. I am waiting to see if a shop can rebuild my spare set before I decide what to do with the originals, they'd need rebuilding though, but are in good shape, seals around the pistons still so don't think they'd be rusted. Just got a call that a shop is looking into rebuild kits for the caliper set i gave my dad to look around for me. (didn't want to ship them to get them rebuilt) I do know they are originals off of a 69 disc car though.

Chatt69chgr · February 01, 2007, 01:46:44 PM

The price was going to be something like $200-$225 or so as I recall. The bellcrank would not be included I don't think. It is strictly a junkyard item but Chrysler used this apparatus on 10 years or so cars so scoring one shouldn't be too difficult. They told me that they actually did get one in from their supplier but didn't like the quality. That was last year. So they are supposedly working with the supplier to get the part in stock. You don't actually have to use this particular booster if you need one right now. The midland ross was used in 1970. If one had to, they could use one of those to get the car going and switch out the correct booster later. There are some good tech info on the piratejack site. One place I would be wary of is Master Power Brakes. They fixed their website so you can't access the tech info until you actually buy something from them. I called their marketing guy about this and he said they didn't want anyone stealing their info. But you can order a $5 fitting and then be a customer and access the tech info. He wouldn't make any exceptions and was quite nasty about the whole issue even after I explained that I needed the tech info to make an informed decision on buying some of their stuff. Go figure. Their whole claim to fame seems to be to take advantage of the paucity of information on disc brake upgrades to sell you a "package". They really don't want people doing their own thing. Personally, after my experience with them, I hope MBM puts them out of business.

My restoration book states The Midland booster part number is 3004625, and the Bendix unit used part number 3004627, except for the Hemi models which used P/N 3004626. As for the number of nipples, cars with concealed headlights had at least two nipples, one for the vacuum line from the manifold, and one going forward, I'm assuming a vacuum supply for the headlights?

I have figured out it is my check valve that broke last year, and now I'm searching for a new one for my 69' R/T with a Bendix disc brakes system. Anyone know someone who still has any check valves?? I'm coming up empty.

Thanks.

I went out to look under the hood, Mine has the vacuum line on one side, and a smaller nipple for headlights?? on the other side with the broken nipple on the forward facing surface. I looked at www.Rockauto.com, and checked under Raybestos CV89005, it only appears to have two nipples. Shouldn't it have three like the one that is broken on my R/T? Someone mentioned earlier CV89004, but that part number no longer appears valid.
