[urq] ATE Aluminum Brake Booster / Servo -- Update on Rebuild ing kits

[Robert Pastore]

This morning, I continued my insanity, and spent the morning driving halfway
across the state to meet with a hydraulic seal manufacturer.   Fortunately,
the owner of the business was a car nut too, and agreed to make the 2-piece
Teflon piston seals (2 needed per servo) since the size was not a stock item
in any reference book.   Minimum order was 50 pieces, or $250. So now, I've
invested almost exactly what a new servo would have cost!

I'll ship anyone who contacts me about a kit in the next week or so at
approx. my cost = $35 shipped.

The kit will include: 
see: http://www.quattro.ca/Urq/Brake_servo_guide.pdf

-The five o-rings & seal that are shown in the bottom left picture on page 2
of the guide.
-Two 2-piece pistons seals as shown on the piston in the guide.  These are
seals being custom made, and are Teflon outer seals, each supported by an
internal o-ring.
-Part # 357 611 243 Gasket between brake Servo and Brake tandem master
cylinder (now with a dealer cost of $8.91)

I'll have the piston seals by the end of the week, and I already have the
rest of the parts on hand.   

I don't plan on keeping any kits on hand for the future (other than for my
own needs), and although I've now got a lifetime supply of o-rings, the
thick oil seal is hard to come by, and the pistons seals are being custom
made. So please, if you think you might need to rebuild your servo at some
point in the future, take one now.

If I happen to recoup my costs, i.e., have my fellow urq-ers request 15
kits, (so that my net cost is equal to yours) I'll donate a few kits to
URQ25, and the rest of the money to Dan.

Also, I owe a thanks to Sean, who *I think* is the person who prepared the
guide that is hosted on Martin's site.   Also, another thanks to Ben Howell,
who is sending me an iron servo, so that I can identify the differences in
the internal components between the iron and aluminum servo.  I've heard
that one or two o-rings and maybe the seal are different.

If you have an iron servo, and want a kit, please email me.   I'll do the
work to find out what changes I need to make, and if there's enough demand
to cover the cost of the changes, I'll go ahead and put a kit together for
the iron servo too.

Remember to register for urq25 North America this week -- the price
increases after Friday!

Best regards,

Bob

Thanks to Jim Pasqualoni & Ben Howell, I've been able to track down the
necessary seals and o-rings to rebuild the ATE aluminum hydraulic brake
servo.
Martin Pajak has a great FAQ on the servo up on his site,
http://www.quattro.ca/Urq/Brake_servo_guide.pdf , but it seems that nobody
is putting a repair kit together anymore.

The servo part number is 857 612 107 A, and it has a current list price of
$725.81, and sells for $650.15 at Worldimpex.  There is no repair kit listed
in ETKA.

The parts needed to repair the servo are the 5 O-rings and 1seal listed on
Martin's site, plus I found and included the seal that sits between the
servo and the master cylinder which isn't show on Martin's page.  From what
I'm told, the kits used to be available from Sport Wheels for $50.

I had to buy some of the o-rings in bags of 100, others in bags of 25 etc,
so I can offer kits to anyone who needs one for $25, shipped anywhere in the
lower 48 ($20 kit + $5 shipping) 

Please email at rpastore.animalfeeds.com if you have any interest.

I hope i'm not breaking rules with this post and realize that maybe this
should be posted in the marketplace, but my intention isn't commerical, it's
only to help out fellow members of this list save a ton of money on a
potentially expensive repair.

Best regards,
Bob
