1989 BUICK REATTA User Comment / Complaint

I'VE HAD MY REATTA FOR 10 YRS.I'VE DONE A COMPLETE OVERHALL OF THE ABS.STARTING WITH MASTER CYLINDER ACCUMILATER ACUATOR MOTOR ALL FLEXABLE LINES AND BRAKE CALIPER. FOLLOWED BY SYSTEM FLUSH WITH FRESH SYNTHETIC FLUID. I DID MOST THE WORK MYSELF BUT IT STILL RAN AROUND 1600.00 . THE BRAKES HAVE FUNCTIONED FLAWLESSLY FOR THE PAST 9 YRS. I ALSO FLUSH THE SYSTEM EVERY TWO YEARS.I ALSO REPLACED THE BRAKE CONTROL MODULE OR BCM. THE BUICK SERVICE MANUAL IS HARD TO FIND BUT A MUST.
