New Brakes....No Stopping Power....help please

[tomtom72]

Just a fwiw on the early ABS modules w/out a bleeder if you work on the system and then bleed, no air went into the ABS nodule. If you didn't get all the air out, and then activated the ABS system then you could get air in the ABS module, maybe. Depends where the trapped air is in the system.

The Tech1A + the ABS software will cycle the ABS, and using a pressure bleeder you can bleed the entire system at one sitting.

Or, you can get the air out manually, take a test ride and stomp the brakes to activate the ABS a few times and then redo the bleed. I do believe that when the ABS does a self test it only cycles the valves using the solenoids and no fluid is moved thru the system so if you had any air left from manual bleeding it would not necessarily get into the ABS module. This is how Jeff explained it in one of his posts if I remember right.

another fwiw, if you work alone the speed bleeders are worth the trouble to install. The one caveat is that you can not ignore the sealant on the threads, as it will wear out with use & leak air. I did minor work on my brakes and it took forever for me to get the air out working alone. The speed bleeders helped but still it took a few sessions to get it right. My next thought would be to use my Phoenix gun to do a reverse bleed as it would proly be quicker & more effective as far as working alone would be concerned.

I just figured to toss this out for your consideration as I found this system to be more troublesome to work on than my 72's brakes with respect to bleeding manually. I think it's the extra length to the brake lines due to the ABS plumbing.
