Back in '91 I brought my GN to a local dealership for a Powermaster recall. They replaced the brake switch with part #18018141 and noted on my work order,"compliance w/brake switch recall". Since that time, I have heard through various guys in the Buick community that the accumalator and combo(proportioning) valve which was to be replaced with a brass unit were also part of this recall. Does anyone have the staight scoop on this? I will be installing a "Max Torque brake launch kit" and would like to swap out for the correct recalled parts with my local dealer while I have things apart! Thank you ------Brian
