 |

Wolfsburg West just announced the availability of new (not rebuilt)
boosters, made by themselves, for both early (71-mid 74), p/n 211611905,
and late (mid-74-79), p/n 211612103, busses with disk brakes. Both $178.40.
I'm beginning to like those guys at WW.

That's exciting!, hopefully someone can post a review of the part when they get one.

Wow, that's excellent. All their WW reproductions I've installed have been great fit and quality. No core charge either

Great Price...
In 06 I bought two rebuilt boosters from them; for $285 each + a $50 Core charge, so I could have some spares in stock, they came unpainted and from different re-builders, one without the boot :0(
The new ones sure look purdy!

Just got mine. Ordered and delivered from WW within a week. I compared it to to an original, and it looks identical (which I would expect). I'll report back after installation and testing, but it will be awhile. I plan to do the whole brake system, minus steel brake lines. I like good brakes, and at the moment mine are marginal.

Just received one of these (the early 71-74 model), and there are a few things worthy of mention:
1. The vacuum connection on the rear of the unit is not the correct size for the stock 12 mm ID vacuum hose. It is 3/8"in. diameter (EDIT: actually 10.2/11.3 mm), with a somewhat
larger bulge at the tip. What the hell? This makes me wonder exactly what does "made by Wolfsburg West" actually mean? Why would
they make a part for VW's that doesn't fit a stock VW setup? I suppose this discrepancy could be fixed by putting a "sleeve" over the nipple
to increase the size, but I think an appropriate sleeve should have been included with the booster, or the nipple should have been made the
correct size to begin with.
2. The pushrod that fits into the master cylinder piston was too long. There is supposed to be some clearance between the pushrod and the M/C
piston (specified as 1 mm for non-booster M/C's), but the unit I received had "negative" clearance, i.e., the piston was compressed when
a known good M/C I had on hand was bolted to the booster. As luck would have it, the push rod has a threaded, adjustable tip, with a knurled
locknut, and I was able to screw the tip further into the pushrod shaft to achieve some clearance. Again, What The Hell? I suppose there might
be differences between M/C's (I tested with a Varga/TRW M/C), but if so there should be a PROMINENT notice included with the booster that
this might be an issue. There is a large potential for some seriously screwed-up brake systems here.
3. There are a multitude of detail differences between the WW booster and an original ATE unit, and as would be expected for a unit that sells for
less than 50% of the price of an original ATE, the WW booster suffers by comparison on most of them. One that stood out for me was the big rubber
boot at the front: the ATE boot feels sturdy and snug, the WW boot seems flimsy and worryingly loose.

well, that is up to the installer to check everything. for all we know, it is set up for a ATE master. who's to say that the flange thickness from a Varga, ATE etc is the same.
proper set-up = good mechanic
the rest, i don't know what to say. other than your boot complaint, the rest is workable imho. i do agree, i am sick and motherf#king tired or making new stuff work, so i feel your pain in that respect

Flange thickness got nothing to do with it. Not 5 in a 100 bus owners would even be aware there could be an issue there, the original stock parts were
just supposed to work due to correct dimensioning, there were no user-adjustable parts involved. I thought a WARNING was in order.

Agreed, a genuine part would be expected to be a direct bolt on with no adjustment required because they are all manufactured to the same tolerances. Props to WW for attempting to duplicate some of the most precision parts ever mass produced, at least they anticipated some error and allowed for adjustment but you are correct a warning or instructions should be included.
And thanks for the review

I finally got around to installing my new WW brake servo. I had some reservations about doing this, as info from W.W. indicates
that they have been the victims of a "bait-and-switch" scam by the outfit that produced these, i.e., they were provided with
sample units which met WW's specs and (presumably) performed to WW's satisfaction, but (at least some of) later production
delivered to WW failed to do so.
Re: the pushrod length problem I noted in earlier post: WW states they specified a 1 mm pushrod protrusion from the M/C mounting
surface based on their examination of several OE boosters. Indeed, I have a new ATE booster on hand which has a 1 mm protrusion,
and my (I assume) original '71 ATE booster has a .5 mm protrusion. Nevertheless, both my 12-yr-old ATE and 16-yr-old Varga M/C's
will have zero (or less) pushrod-to-piston clearance with any pushrod that protrudes beyond the booster/M/C mounting surface.
Bolting my Varga M/C to the new ATE booster clearly results in a partially blocked compensating port, but not so with the ATE M/C.
Make of these facts what you will: I see a clear need for some thin M/C mounting shims, but have never heard of such an animal.
The pushrod length of the WW booster is highly adjustable, as a I mention before, and I set it flush with the booster surface before
I installed it.
RE: the wrong-sized vacuum hose nipple on the WW booster: I cut off the end bulge (which is really not suitable for the type of hose to be
connected) with a tubing cutter and slipped on a length of some snug-fitting vinyl tubing I had. This resulted in a nipple with
13 mm O.D., which worked fine with the stock wire-reinforced vacuum hose.
For no good reason I can think of, the mounting studs on the WW booster are excessively long, and required a deep socket to get
the nuts on.
After installing the booster, I fired up the engine and played with the pedal some. Every time the brake pedal was released, there would
be a very noticeable engine rpm surge. My old ATE booster never did such a thing.
Then I went for a test drive - and man, was it horrid. Beyond horrid. There was almost no modulation possible on brake action. It went from
very light braking to almost being flung thru the windshield with the tiniest increase in pedal pressure. I went about my business for the
rest of the day, and it required total concentration on my delicate foot pressure to avoid slamming on the brakes. Needless to say, that
bogus WW booster came out and my old ATE unit went back in, and all was well again.
Weight of WW booster: 5.5 lbs
Weight of old ATE booster: 6.8 lbs

So sorry to hear that, I hope you are making WW aware of your findings 
I spent part of my afternoon saying nasty things about the Chinese or more precisely the buyers who accept that second rate crap from some of those crooks with a bag full of crappy slightly too thin crimp style wire connectors, nowhere near as much work or danger as what you went through

I've not ever had any good luck with aftermarket new boosters. I've seen several of them fail, no matter who they are from, within a couple hundred miles when installed on customer's buses. For this reason, we only have old boosters sent off to be rebuilt and they have never had an issue of any sort. Just my two cents.
p.s Btw, we send the boosters here:
