Yes, the brakes seem to function properly. After installing the new O2 sensor & trying to pry one of the ABS sensor out (started to crack the case so stopped) I cleared the codes and drove about 5 miles to the auto part store. New codes:
C0200 Right ABS sensor malfunction
C0205 Left ABS sensor malfunction
C1223 General ABS system fault
C1241 Low battery positive volt
C1256 Accumulator Low Pressure...Confession: This might have occurred because I tested the brake by pumping them 7 to 8 times while idling and the ABS warning light came on and it buzzed. Unfortunately the Accumulator is already on order.
I wish I had techstream ->
