Brake Booster Vacuum Hose Grommet?

[Clatter]

OK,
We were trying to replace the power brake booster,
And when it came off,
The grommet at the barbed input,
Where the vacuum line comes in,
Was kind of gooey and chewed up.

Part #71(?)

The barbs seemed to have pulled the grommet apart.
Can't seem to find it mentioned for sale anywhere..

Upon trying to re-assemble,
We tried using one of these reservoir tube grommets to no avail.

Maybe just get a fresh hose on?
This?

Front to back? Huh?

Maybe just a blob of black silicone might do the trick?

If anyone here has this one sussed out, please share the secret.
Much thanks!

Looks like the Master cylinder reservoir does not get a rubber grommet.
thnx to mayor ratwell and jerseylooker.

Note: #4 is the master reservoir Damon has. #4 is the 73-79 w/servo. Diagram leaves a lot out.

#2 is the Master reservoir wo/servo. Note No grommet on master reservoir.
#6 is the Fill reservoir that does have the grommet though.

my 1977 has a grommet in the booster that the barb goes into. The hose then clamps to the barb. Part #71 is the clamp. It also shows up on the Early bay fiche. The grommet does not, or at least I can't find it either. The fiche shows the booster with a nipple on it. My 1977 is not like the fiche. I'll keep looking.

edit: I Googled "ATE Brake Booster grommet" and got quite a few hits that kinda look like what I would expect to fit the ATE booster. They range from $1.20 to $10 but all look alike. Good luck.

I grabbed this photo out of the Ronnin10's gallery- it shows the grommet

The part you are looking for is 211-611-833D. It’s used on all of the connections of the hard plastic lines including the check valve (5) if I am not mistaken.The grommets that go into the hard plastic line between the upper and lower reservoir is 211-611-833C (2). Bughaus has both in stock.

I would not try to alter the hard plastic hose whatsoever. You are asking for big trouble. They are pre formed. I don’t have both grommets in front of me but I do recall that they are different. The “top” of the grommet is obviously different just looking at it. I think but am not sure that the “D” grommet may be thicker thus changing the ID. Go to German Supply’s website which has a very good picture of both of the grommets in question.

no - like this on the booster. The inner grommets TCash showed go inside the plastic hose ends to seal them. Turn to like glue over time. Not used where the barb goes into the booster. Autohauz is where this photo comes from - it looks like the one on my 1977 booster. The part or one like it does not show on the VW fiche.

The bigger question is did you get all of it out?, or is some still rattling around inside the booster?

I'd go for a trip to the wrecking yard and eye up some other cars, that looks like a somewhat common part on many cars/trucks/vans.

I have read clatter's comments many times and we are interpreting it differently. I do know what these parts are. You'll find a thread back around 2009 where I detailed which piece goes where. My 1977 has all these parts and I had to source them because the PO cut some off to use garden and aquarium hose rather than the correct parts.

Where the hard plastic hose slides over things, the rubber grommets shown go. They get gooey with age. There are several of those used on the hard plastic line - each place the plastic line goes onto something one is used. There are two different diameters.

Where the hard plastic barb goes into the booster itself there is a round rubber grommet that also gets gooey. When the barb that goes into it is pulled out it comes apart. That part is not on the fiche.

There parts go on the hard plastic line where it slides onto the booster fitting.

This part goes on the booster where that fitting goes into the booster. It is NOT on a fiche. It comes with the booster but some places sell it separately.

Guess I should have told you guy's that I need new glasses and a 1000 watt halogen light to see anything.
I got back under there today and stuck a screwdriver in the end of the plastic line and guess what pops out. The gooey old grommet. Might help if I removed the old grommets.

Damon got under there and installed the 211 611 833 D Brake Grommet, Booster barb to Plastic vacuum hose. I think Damon said the square end located in the hose.

Thanks to all that posted.

Abscate I would have been blind a long time ago if what your dad said was true.

I was putting my booster vacuum hose back on when some hard rubber fell out. It appears that on both sides of the check valve there is a grommet sleeve that goes in both hard plastic pipes.

Is this what I need?

I know I need two in this particular spot but will I need more further up the line?

I am currently replacing the last piece of hose for brake booster on a 1971 bus. It is the piece that connects to the forward most side of the booster (toward front of bus) and other end under left side of bus (where driver's hip?? would be above). All other hose I have used is 15/32" vacuum booster hose, and it fits fine, but this last piece that I have to replace is 5/8-3/4" inside diameter. I am not sure of the rules so I apologize if this is not allowed, but I screen shot someones else's picture to show where the front end of the hose would connect. My question is what is the correct size, length, and type of hose, and are there any grommets that are needed? Also, where does the other end attach, what is the purpose??
Any help would be appreciated!

[busdaddy]

The hose on the front bellows is the atmosphere vent, it doesn't have to be vacuum rated, any bulk watercooled heater hose will do just fine there, your FLAPS should have 5/8" ID on a roll by the foot.. Even clear vinyl hose would work, it just has to be waterproof and not kink.
