You can see the piston through the ports for the resoirvior, set the clearance before putting the resoirvior on. |
Again I say: If you replace the old one with a new Airtec, which bolts right up and works fine by the way, simply measure how much your old push rod protrudes from the face of the booster, grab your 7mm and 8mm wrenches and adjust the new one to that length and you are off to the races.

Skills, I think you are thinking of the Brazilian booster. These Airtec ones fit just fine, work just fine. Any marginally competent shade tree mechanic such as myself can replace one in a few hours. ( Time Includes M/C replacement and brake bleeding)

that will be your best bet really. I used one for a client when they were first out to market. it was horrible. I don't think you'll be let down by a rebuild

Guess I drank the koolaid, got sucked in by the hype. It'd be nice to have a new one, but you're right - it looks like a sendout rebuild will be the way to go. Thanks for your input.

I wondered about that statement too, but had no idea how much vacuum is usually generated (just now realizing I could have measured it easily...). Do many other cars have vacuum limiters?
Perhaps that's why the poster's on the original thread had problems with the Airtec booster - too much vacuum for it. If so, is there an aftermarket vacuum regulator you could put in-line, like the fuel pressure-regulator I have between my fuel pump and my 34Pict, that might make it work better?
Obviously they should have designed it for the working pressure in the bus, but given our limitations, might that be a workable solution? Maybe that's why that booster works for some and not others - variation in vacuum developed in their intake manifolds.
Anybody tried that or have any thought on whether it would work?

I'm confusing the hell out of myself by following two different threads on this topic!
Thanks, EIS is a new one for me!

I fitted the WW servo in the end. Adjusted the connecting rod and bled everything thoroughly. I immediately felt the same lack of brake modulation kreemoweet noted in his review. Brakes are very sharp indeed. It's unpleasant.
Anyone else tried this servo and had different results? Is there any adjustment I can do other than connecting rod? |
I don't know if it is the same brand as the WW one, but I bought mine for my '71 at EIS and it is branded Airtec. I set the pushrod the same protrusion as the one I removed and bolted everything up and it works great. |
So I've got the same question. Is the WW booster the same as Airtec? One thing that spooks me is the photos on the Airtec sold by Jbugs and the "WW brand" both show the same blue attach point on the front end. That's not conclusive but suggests they're the same.
- Jack |
Don’t know for sure, but common sense tells me that 2 manufacturers wouldn’t start building these at roughly the same time with a similar look for such a small market. I suspect the WW is an Airtec.

Can anyone provide a link or phone # to the rebuilder for my original ATE brake servo? Many thanks!

Don't forget, and as discussed in my original thread linked to above, that even the genuine ATE booster has an
incorrect push rod setting (for use with original stock master cylinders), and there is no adjustability in that pushrod
length in the necessary direction (shorter). Either a M/C shim or machining of some sort will be required to use it. |
I just measured how much the pushrod protruded from the face of the original booster and adjusted the new one to the same amount of protrusion or lack thereof. Took maybe 2 minutes if that.

Agree. It's only a pain if you neglect to adjust it before installing it under the car along with a master cylinder and fully bled brakes.

The WW booster pushrod the same clearance as the original ATE pushrod. So I concluded that the whole thing was an inferior clone. I dried out, cleaned and refitted my original booster. Proper modulation returned along with more tactile pedal. My advice is to either rebuild your original, buy used here and get it rebuilt or save for the genuine ATE one.
Lesson (re)learnt. You get what you pay for.

Tim,
This aftermarket booster is a bit different in that the very tip of the rod that inserts into the MC is adjustable using very small wrenches. It also has the smaller, like 3/8 nipple, as opposed to the usual 1/2 inch or so size nip. Personally, larger nipples appeal to me. Your tastes may vary.
