I want to thank you all for not bidding against me . . .

Hopefully it will get here this coming week (by the time I'm back in town - another business trip next week).

It arrived Friday (yesterday).

The "pigtail" turns out to be the power wire for the pump motor. The connector is built into mine. Otherwise, it looks the same.

I'm out to the garage to install it now. Anything special required to bleed these things? My Haynes is silent on this type of unit.

there is a special bleeding techinique. you open the bleeder valves in each wheel one by one, and you need to pressurize the reservoir to force the fluid down into the lines, GM suggests a tool designed just for that, but I used a large cork with a hole drilled in it, with an air nozzle in it set at 60 pounds. Pressurize the reservoir and open the bleeded screws one by one untill the air bubbles stop coming out.

Sounds like a standard pressure bleed. I'd agree that is much easier, and can be done by one person, but is that the only way to do it?

I had an alignment done last year, asked the shop to bleed/flush the brakes while they had it. When I went to pick it up, they said they decided not to do it. Something to the effect of "having trouble with that type of brake system" in the past.

I had forgotten how much fun this job is. Especially the under-dash stuff - plastic cover that is the first one installed of several, needing to get your face, hand, and light in the same space while laying on your back, etc. Then under the hood - having to reach over from the passenger side to get the back two lines off (requiring wearing my glasses upside down so I could focus at that distance - Varilux, you know), working around dipsticks, cables and hoses, etc., etc., etc.

Perhaps that'* why I had forgotten. . .

thats basically how it explains it in the FSM. only thing special is that the reservoir needs to be pressurinze, i tried without pressure but it did nothing. other than that it pretty much the same

Guess I'll see if I can rent/borrow a pressure bleeder.

Default Success!

Couldn't find a pressure bleeder quickly (Harbor Freight is opening up 2 blocks from my house, but not until the 28th ). So, I went with the Mityvac.

Took awhile for the pump to build pressure, cracking the jumper line between the pump and main body seemed to get that going (burped into the reservoir when I did that). However, once I started the bleeding operation it wouldn't draw fluid unless the pedal was depressed. So, it turned into a "standard" bleeding operation, anyway. With the key on and the pump running, the battery ran down before we got it done - had the charger on 15 amp while we finished - and ate dinner). I picked up a gallon of brake fluid from NAPA (just opened up right next to the Harbor Freight), used over a quart just to fill the unit, then bled out more than a quart from the 4 wheels before the fluid cleared up and bubbles stopped.

It seems to be working better than the original and used units ever did. Hope it continues that way!

Since the eBay listing probably won't be up forever, I'll post the guy'* info in case someone else needs a unit rebuilt:

Invasion Auto Parts
6250 Lankershim Blvd
North Hollywood, CA 91606
(81506-8005
(81506-5186

I "won" it for $295 plus shipping (and $75 core charge). I don't know for sure, but he might rebuild yours for that.
