I have a question related to this topic. If anyone knowledgeable could help, I'd appreciate it. It started when I realized that both rear brakes of my Oldsmobile Intrigue 1998 had quit working simultaneously. I traced the problem back to the ABS. I got a replacement ABS but while trying to replace the ABS, I had to remove the ABS motor pack in order to attach the modulator to the master cylinder because of the design. As I pulled the ABS motor pack away from the modulator, the spring loaded gears released. Is there any way to reset those spring loaded gears correctly and if not, do they need to be loaded for the brakes to work? The ABS has not worked for years, so I don't care about that. I do care about the having my rear brakes functional. If anyone could help, I'd appreciate it. Thanks!
