1994 GMC YUKON Service Brakes, Hydraulic Problems

WHEN BRAKING HARD, ESPECIALLY IN A DOWNHILL MOTION ON WET OR SNOWY ROADS THE BRAKES LOCK UP. REMOVING ONE'S FOOT FROM THE PEDAL DOES NOT RELEASE THE BRAKING ACTION. ONLY WHEN THE TIRES STOP SKIDDING DOES THE BRAKING ACTION RELEASE, ALLOWING FOR ONE TO "TRY AGAIN" BY APPLYING THE BRAKES MORE GENTLY. BY THEN THE VEHICLE IS NEARLY STOPPED ANYWAY. I HAVE NEARLY SKIDDED INTO INTERSECTIONS OR CARS IN FRONT OF ME ON AT LEAST FIVE OCCASIONS.*AK
