Thanks so much for the help. Just hate to replace it if there may be another problem...but it certainly does seem to be related to the motor electrical system. Take care and Merry Christmas!!
Hello, I have a 1987 Buick GN, basically all stock. The original PM brakes are having an issue with the motor "ailing" to operate at the worst times...while I am driving! Think this is a common problem. I have checked the accumulator, pressure switch etc. and they seem to be within spec...
