Re: 1992 DeVille Squishy brakes
Doing shoe and pad replacement does not require bleeding so if they were bled at all, you would have asked them to do it. A sinking pedal is either a by passing master cylnder or air in the lines. In order of diagnosis I would make sure the rear drum brakes are adjusted, can you hold the car in gear with your foot on the parking brake?,if not, too much clearance, low pedal. Second, have the system pressure bled. Third, if the low pedal remains, replace the master cylinder.
