My ANTILOCK light will come on and go off after restart. I been noticing, just before coming to a complete stop, strange pulsation from brake pedal.
ABS brain,sensors or pump? How can I determine the problem?

 

I had the same kind of problem with my 86.5 about a year ago. Turned out to the ABS relay. They are a little pricy ... try to find a used one if you can or if you have another 928 in the area ask to swap relays and see if you get the same symptoms on their car before you purchase a new one.

 

Anyone have a used relay kicking around? What did you try to determine your fault being the relay.
Thanks
