Hi @ everybody... well, what shoult i write ? my name is sven and i come from west- west germany, near the boarder to the netherlands. i´ve 3 cars: - chevy caprice coupe´ 1979 - bmw e39 and last but not least a beautifl blue buick regal from ´91. but sice one year 1´ve big problems with the buick... the powermaster braking unit makes me crazy. i´ve also bought one in the netherlands on a yunkyard, but also this one doesn´t work up till now... (remember: one year is over... ). so i´m normally a good machanical so i´m not afraid of build in- build out, trying everything to make it work... but now i´m going to read, read and read to hape that s.o. can help me. on autozone i´ve read everything about the PM III, nothing of this works till now. also i gave the car in 2 different workshops. no one is able here to find the error. so i hope i´ll find something here
