ight fellas i posted a while back about my ABS pump makin the *grrrrrrrrrrr* sound on start up for about 60secs about 2weeks ago, and i was told to try bleeding the system completely to rid any air. well, this afternoon me and a buddy completely bled and refilled the car, and when i started it up, *grrrrrrrrrrrrr* wtf???? i know we did it right, so what could be wrong now? i heard something about an o-ring possibly being the problem...any suggestions...thanx in advance to anyone who can offer some help!!!!!

 

mine goes "grrrrrr" when i start it up, but only for about 1-3 seconds max.....what kinda car? year?

 

I remember BSQ posting about how a common reason for the ABS light to come on is a bad o-ring on the ABS modulator.
