Hello all, I have a new to me 1990 Oldsmobile 98 Touring. I'm having trouble with the brakes. Right now it feels like I have manual brakes, and will stop given enough time. Pedal is hard as a rock. I plan on pulling the codes tonight but after doing some research, Im leaning towards it being the accumulator. The Teves unit and all involved parts seem impossible to find new/refurb. I plan to go to a pull apart this weekend and look for one. I feel as though my options are replace the system/or accumulator with a different one or switch over to booster/master cylinder setup. Any input would be appreciated!
