Do the brake and APS lights do a quick flash and then turn off? If so I might just be the Brake Accumulator (Black dome about 3” in dia)on the backside of the Master Cylinder. You can do a search on SCCOA for a replacement. Around $100 I think, I need one for the 89 I just started driving. If I find out anything I’ll let you know. There is also a rebuilt replacement for the Master/ ABS unit also but is around the $500 level I think.
If you need any SC parts new or Used give Victor or Diana at
http://www.spinningwheels-sc.com/ a call, they are in Ocala. He told me today that he had a good used Master/ ABS unit on the shelf. They are in the process of redoing their web page so if you don’t see what you want give him or Diana a call or an e-mail. She is very well versed in SC parts also.
Looks like you had a good first day with the SC.
