Thanks for input horse482 and silverado122775.
I do hear what I think is the abs motor when this occurs, and it feels like a rotor is warped before it pulsates. Silverado are you refering to the abs wheel sensors? I do not have a Haynes repair manual and autozone.com does not have it online either, so if someone know the correct brake bleeding procedure I would greatly appreciate the information so I can try bleeding system properly. Thanks again for all the great info.
