PLEASE HELP!!!!! I've purchased two sc's, an 89 and a 92, and they both have the same abs problems.the 89 I've given up all hope but the 92 I was able to save well least for two weeks.I replaced the accumulator ball and the brakes worked fine for two weeks. Then while driving the brakes would cycle from hard to soft.me and my mechanic can't figure it out. I'm done with this abs crap. Does anyone know how to use a conventional system on a sc from a same year lower model?
