version today that i purchased from gmpartsdiect. had to use a 2.5 foot breaker bar to get the old bomb loose with the 8mm hex fitting. i was a little nervous, as it felt like i was twisting something that shouldn't be twisted before it let loose.
i did pump the brake pedal about 40 times before starting this process, and inspite of that, when i started to first loosen the old bomb, there was still a spray of brake fluid from the threads. i let it sit for a moment, then continued to unscrew it. when i got close to the bottom of the threads (almost completely unscrewed), there was a loud hiss and a cloud of hot brake fluid vented to atomosphere. first hint, don't do this after driving the car for any time, brake fluid gets really hot! or at least be very careful!
the new accumulator threads right on, and it does come with a new o-ring. i did plug the m/c hole with a paper towel and cleaned the crud from around the opening to prevent dirt falling in accidentally. i also used a paper towel plug to chase the threads on the port to get rid of dirt there. snugged the accumulator up hand tight, and then tightened it to 30 ft lbs with a torque wrench. again, while tightening it, i was a little nervous as it again felt like something was twisting that shouldn't.
i did mean to just hand tighten first, then push brake pedal down to bleed air from the threads, but i forgot to do that. it didn't seem to make any difference however. i did fill the m/c resevoir with fluid as the level dropped. once i pumped the brakes, the fluid level did come back up, to the point of squirting out the hole in the cap, so i don't know that filling the resevoir is actually necessary.
after cleaning the top of the resevoir and surrounding area (from the fluid cloud)with brake cleaner i fired the car up and let it idle to see if there were any sirens and smoking lights happening.
so far so good, after shutting the car down, i turned the ignition on (but not started) and pumped the brake pedal. it took 20 pumps before the warning lights came on. definately an improvement from the 1 pump then lights that i had been having. took it for a test drive, and did a few test stops, no issues. one sorta side effect that i noticed (but haven't fully tested yet) is the car doesn't lurch to the left when i slam on the brakes. it did squeal the tires when i stomped them hard. i do have abs on my car. i will do a high speed panic stop test and see if the lurch is still there or not.
the long and the short of it is the gm part seems to work fine as others have said. i figured i'd give a complete report of my expereicnce. it is a simple swap to do if your car is having accumulator issues. i think the $120.00 total cost for the gm part makes it silly to consider the $400.00 saab one unless you're really really concerned with originality.
::sigh:: while i was at it i figured i'd rotate the tires, and now there is a sort of rotational sounding noise from the front that wasn't there before. i'm hoping it's the tires, i'll find out when i swap them back next weekend. i guess the continuum is sneaking in lol.
maark :-)
