Since you have a 92, your brake system gets its pressure from an electric motor that can possibly be "deactivated" by a failed ignition switch. I'm not talking about the ABS system....I'm talking about the BRAKE SYSTEM.
You can literally loose your power brakes because of a worn out ignition switch. I don't know how you drive your SC, but if you're out enjoying it, you don't want your brakes to go out.
CHECK THE IGNITION SWITCH
Like Ken and Ralph have preached numerous times, it's cheap, its easy to get to / replace....it's even easy to CHECK.
One of my SC's had an ignition switch starting to fail...I put it off...it still worked most of the time.
On my way to work (driving fast / running late), my turn signals stopped working for awhile....hmm...weird... As I approach the U-shaped interstate exit @ 60mph+, I also find that I have no power assist for the brakes....had I planned to push that curve any harder, I probably would have wrecked the car.....for a $13 part that I knew was going bad.
The large starter relay in the engine bay goes bad too...usually I think the contacts inside get dirty/corroded...I've had multiple failures of those in the past few years. You can't jumper it to get it to start when that's the problem though (unless you make good contact)....my wife's car has had that problem for some time.
