Why would thre rear brakes stop working on a 98 Olds Intrigue?
Don't know of any brake symptoms unique to Intrigues. How do you
know it is the rear brakes? If you detected the rear brakes being
bad because the emergency brake doesn't work, probably a snapped
cable. Assuming the car still stops (front brakes still work), you
could have worn pads (unlikely), a broken brake line (probably will
cause the front brakes to quit working soon - look for leaks), a
faulty master cylinder (rear brake cylinder shot - unusual). I'd
take her to a brake shop if you can't diagnose the cause. I't hell
when you are headed for a school bus and can't stop.
