INITIALLY WE HAD THE BRAKES CHANGED, THEN WE TOOK IT TO THE REPAIR SHOP AND THEY WERE TEST DRIVING IT, AND TRIED TO STOP THE TRUCK, AND RAN INTO THE WELDER IN THE SHOP AND DESTROYED THE WELDER AND WRECKED THE FRONT BUMPER OF OUR TRUCK. WE THEN HAD THE BEARINGS WORKED ON. AFTER RESEARCHING ON THE INTERNET, I FOUND WHERE SOME TRUCKS WERE RECALLED FOR THIS PROBLEM OF THE ANTI LOCK BRAKE SYSTEM ENGAGING AT SLOW SPEEDS. OUR TRUCK HAS A VIBRATION IN THE BRAKE PEDAL WHEN TRYING TO STOP, BUT IT ONLY OCCURS AT THE FINAL STAGE OF STOPPING, AT SLOW SPEEDS. IT HAS OCCURED NUMEROUS TIMES, AND WITH NO WEATHER CONDITIONS ON THE ROAD.
