2001 Chevrolet Blazer service brakes, hydraulic problems

“THE "ABS" AND "BRAKE SYSTEM" LIGHTS STAY COME ON AND STAY ON AT DIFFERENT TIMES. I HAVE HAD THE BRAKES CHECKED AND THE SYSTEM CHECKED AND THEY ARE COMING ON FOR NO REASON. *TR”

“IN THREE DIFFERENT OCCASIONS, 2 IN 06 AND 2 IN 07 THE BRAKES FAILED TO STOP IT'S AN INTERMITTENT INCIDENT. IN 06 AFTER INCIDENT, MASTER CYLINDER BRAKE WAS CHANGED (NOT KEEP OLD PART). AFTER THIRD INCIDENT, I TOOK IT TO DEALER. THEIR RESPONSE WAS NOTHING WRONG. BUT ON MY INTERVIEW WITH HEAD TECHNICIAN, MENTIONED THAT COULD BE THE ABS ACTIVATING, LIKE READING FALSE INSTRUCTIONS. WHAT COULD BE DONE, HE SAID TO CHANGE THE SENSORS BUT THERE WERE THREE ON THE CAR AND THOSE WERE EXPENSIVE AND THEN THERE ARE MORE OTHER COMPONENTS TO THE ABS THAT COULD ALSO BE THE CAUSE OF FAILURE. I STARTED TO INVESTIGATE ON THE INTERNET TO UNDERSTAND THE ABS AND THEN TO SEE IF I WAS THE ONLY ONE, AND THEN LOOKING FOR RECALLS. I CAME TO AN ARTICLE THAT DESCRIBED THE FAILURE EXACTLY AS IT HAS HAPPENED TO ME ALL THESE PAST EVENTS AND READS:...SIDEBAR: WHAT ARE THE MOST COMMON FAILURES WITH ABS THAT YOU HAVE DETECTED FROM YOUR VEHICLE INSPECTIONS? FOLCK: WELL, IN THE GENERAL MOTORS TRUCKS AND VANS, THE 4-WHEEL KELSEY-HAYES ANTILOCK BRAKE SYSTEM. THE BRAKE PEDAL IS SUPPOSED TO JUST PULSATE A LITTLE BIT AND STAY IN POSITION, BUT SOMETIMES IT GOES TO THE FLOOR. SIDEBAR: WHAT DOES THAT…”

“I WAS IN A DRIVE THROUGH WHICH LOOPED AROUND THE BUILDING. I APPLIED THE BRAKE TO STOP AT THE WINDOW AND COULD FEEL THE ABS ENGAGE AND THE VEHICLE DID NOT WANT TO STOP. IT SCARED ME AND OF COURSE I REAPPLIED THE BRAKE QUICKLY, TO AVOID HITTING THE VEHICLE IN FRONT OF ME, AND I WAS FINALLY ABLE TO STOP. THIS HAPPENED AGAIN A FEW WEEKS LATER AT A LARGE INTERSECTION AT A RED LIGHT. I WAS 7 MONTHS PREGNANT AT THE TIME AND WAS PRETTY SCARED. I HAVE HEARD SEVERAL OF THESE COMPLAINTS AND I KNOW THAT THE BRAKES ON EVERY YEAR BEFORE THIS WERE RECALLED. I ALSO HAD TROUBLE WITH THE BRAKE LIGHTS AND FOUR-WAYS, WHICH STOPPED WORKING. I WAS DRIVING AND THE FOUR WAYS CAME ON. I HAD TO PULL OVER AND ENDED UP HOLDING THE BUTTON DOWN WHILE I DROVE IN ORDER FOR THEM TO STOP FLASHING. SHORTLY AFTER THE TURN SIGNALS STOPPED WORKING. FINALLY, THE SPEEDOMETER TEMPORARILY STOPPED WORKING, THEN SHORTLY AFTER THAT, THE HEAT STOPPED WORKING, THE VEHICLE ONLY BLOWING COLD AIR. WE REPLACED THE THERMOSTAT BUT THE HEAT STILL WOULD NOT FUNCTION. I ENDED UP GETTING RID OF THE VEHICLE BECAUSE OF THE NUMEROUS MALFUNCTIONS. *JB”

“SINCE I BOUGHT MY 2001 CHEVY BLAZER, I'VE HAD TO REPLACE BALL JOINTS EVERYTIME I HAVE A FRONT END ALIGNMENT. THIS YEAR I'VE REPLACED 3 WHEEL BEARINGS, FUEL PUMP, AND I JUST LOST MY TRANSMISSION. I'VE HAD THE LIGHT RECALL FIXED. MY SERVICE ENGINE LIGHT STAYS ON, BUT YOU CANNOT PUT A COMPUTER TO IT BECAUSE IT DOESN'T WORK. MY ABS LIGHT COMES AND GOES. WHATS NEXT? *NM”

“UNWANTED ABS ACTIVATION AND EXTENDED STOPPING DISTANCE DURING LOW-SPEED BREAKING ON MY S-10 2001 BLAZER. THE PROBLEM OCCURS NUMEROUS TIMES A DAY ON A DAILY BASIS. I HAVE ADJUSTED MY STOPPING PATTERN TO ALLOW FOR THE INITIATION OF THE UNWANTED ABS ACTIVATION. *NM”
