Has anyone ever tried the Buick GN Poweremaster brake vacuum conversion kit(Part number BM8743)offered by MP(Master Power)Performance Brakes? If so, I'd like to know, the results you got(Good or bad?)? This is a complete, new, vacuum brake(Replacement) system, for 1985-87 Turbo Regal's and GN's. If anyone has experience with this unit, I would also like to know, if a vacuum booster pump was needed(To achieve the necessary vacuum)or, if this pump was not needed, for the kit's vacuum booster, to operate properly(Enough vacuum?)? The good part, would be if this brake kit, worked good(As is)without needing any additional brake optional accessories? The web site for this company is www.mpbrakes.com. I just found out about this system-so, I'd appreciate getting anyone's input on this? Thanks!
