Question
1989 ccadillac fleetwood 4.5 liter
abs light on. ocassionaly brake light will come on. then brake pedal gets hard.have noticed when this happens master cylinder gets over full. after stopping several times brakes return to normal, but never know when it will happen again. car does not have a booster, but some type of acummulator.

Answer
This would most likely be the TEVES brake system which is very difficult to work on and should ONLY be repaired by an expert brake technician. I STRONGLY recommend that you do NOT attempt to repair this high pressure brake system yourself.
