1994 Chevrolet S10

WHILE DRIVING ON THE BELTWAY (395) IN DC, TRAFFIC HAD COME TO AN ABRUPT STOP. AS I WENT TO APPLY MY BRAKES THE PEDAL LOCKED-UP AND I COULD NOT APPLY THE BRAKES. THE NORMAL ABS SOUNDS WERE PRESENT BUT THE BRAKE PEDAL WOULD NOT MOVE. THE ABS LIGHT NOR ANY OTHER LIGHT CAME ON. I HAD TO STOP USING MY EMERGENCY BRAKE. I PULLED OFF TO THE SIDE OF THE ROAD AND IT APPEARED TO HAVE CORRECTED ITSELF. I CONTINUED AT A SLOW SPEED AND TRIED THE BRAKES AGAIN AND I WAS ABLE TO STOP. WHILE DRIVING HOME TO NEW YORK IT DID NOT OCCUR AGAIN. I DROVE THE VEHICLE TO DC AGAIN AND IT OCCURED A FEW MORE TIMES. I HAD IT CHECKED AT A SERVICE STATION AND THEY FOUND NOTHING WRONG. I CONTINUED TO DRIVE THE VEHICLE AND THE PROBLEM DID NOT OCCUR IMMEDIATELY. ON 4-8-99 I WAS RETURNING FROM A STORE WITH MY WIFE. I WAS ENTERING THE ON RAMP OF I-84 IN MIDDLETOWN NY, WHEN I APPLIED MY BRAKES TO SLOW DOWN ON THE RAMP THE PROBLEM OCCURED FORCING MY VEHICLE TO SWAY SIDE TO SIDE AND ALMOST ROLLING OVER. I CALLED A GM DEALER AND THEY SAID THAT IF THE LIGHT DIDN'T COME ON THEN THERE WAS PROBABLY NOTHING WRONG WITH THE ABS. I TOLD THEM I WOULD LIKE TO HAVE IT CHECKED OUT ANY WAY. UPON THE DEALER INSPECTING THE BRAKES THEY APPARENTLY FOUND THAT THE HIGH HYDRAULIC UNIT ABS PUMP WAS DEFECTIVE AND IT WAS COSTLY TO REPAIR. MY CONCERN IS NOT THAT I HAVE TO PAY MORE THAN $1000.00 TO CORRECT THE PROBLEM BUT THAT THERE ARE THOUSANDS OF 1994 BLAZERS ON THE ROAD AND THAT THIS PROBLEM CAN OCCUR WITH OUT WARNING (NO LIGHTS). IF ANY PART OF THE ABS IS DEFECTIVE THE SELF TEST THAT IS RUN ON THE ABS SHOULD IDENTFY THIS PARTICULAR PROBLEM BECAUSE IT IS SOMETHING THAT CAN BE MEASURED (IE. PRESSURE). MY VEHICLE IS AT PORT JERVIS AUTO MALL SERVICE DEPARTMENT (914) 856-5104. I WOULD APPRECIATE ANY ACTION YOU MAY TAKE IN INVESTIGATING THIS MATTER. NOT EVERY ONE WILL BE ABLE TO THINK OF STOPPING WITH THEIR EMERGENCY BRAKE WHEN THE PEDAL LOCKS UP. I WAS LUCKY TO AVOID AN ACCIDENT.

WHILE DRIVING MY BLAZER, I STEPPED ON THE BRAKE PEDAL AND IT WAS VERY RIGID AND THE TRUCK FAILED TO STOP, MY ABS LIGHT CAME ON, THE DEALER DISCONNECTED MY ABS SYSTEM DUE TO CONTINUED BRAKE FAILURE OR LOCK UP. CURRENTLY THE BRAKES ARE VERY UNPREDICTABLE AND OCCATIONALLY FAIL OR LOCK UP EVEN WITH THE ABS DISCONNECTED. I WAS INFORMED BY THE DEALER THAT THIS IS A COMMON PROBLEM WITH THE BLAZERS.

WHEN APPLYING THE BRAKES THE PEDAL BECAME MUSHY THEN SOLID AND WOULDN'T STOP. OWNER HAD TO USE EMERGENCY BRAKE TO STOP. DEALER REPLACED THE POWER BOOSTER. *AK CONSUMER STATES THAT THE VEHICLE EXPERIENCED BRAKE PROBLEMS SINCE IT WAS PURCHASED, THE RIGHT REAR BRAKE WOULD LOCK UP AT THE FIRST APPLICATION WHEN WEATHER WAS DAMP, CYLINDERS HAD PREVIOUSLY BEEN REPLACED ALONG WITH THE TURNING OF THE DRUMS. CONSUMER STATES ENGINE WOULD STALL WITHOUT WARNING, CONSUMER BELIEVES THIS WAS CAUSED BY CONTAMINATED FUEL BECAUSE THE PROBLEM NO LONGER EXISTS. *SLC

THE CONSUMER HAS BEEN EXPERIENCING PROBLEMS WITH ANTI-LOCK BRAKES. VEHICLE WOULD CONTINUE TO MOVE FORWARD AFTER THE INITIAL BRAKING.. IN ADDITION TO PROBLEMS WITH ANTI-LOCK BRAKES, CONSUMER IS EXPERIENCING PROBLEMS WITH DEFROSTER. IT TAKES A LONG TIME FOR THE WINDOWS TO DEFROST AFTER THE DEFROSTER HAS BEEN TURNED ON. THE MANUFACTURER IS UNAWARE OF THE PROBLEM. *AK
