I WAS DRIVING ON A RESIDENTIAL STREET IN WASHINGTON, D.C. IN MY 2003 HUMMER H2 WHEN I NOTICED AFTER A BRIEFLY TRYING TO BRAKE FOR A PEDESTRIAN THAT MY BRAKE PEDAL WAS NOT AS TIGHT AS USUAL. I CONTINUED TO DRIVE BELIEVING SINCE NO WARNING LIGHTS THEN THERE'S NO ISSUE. I CAME TO ANOTHER STOP AND REALIZED THEIR IS SOMETHING WRONG MY BRAKE PEDAL WAS VERY LOOSE AND ALMOST TO THE FLOOR WITH MINIMAL STOPPING ABILITY LUCKY I WAS NOW AT MY HOME I COASTED TO MY HOME BY NOW THE BRAKES HAVE BLOWN COMPLETELY I HAD TO USE THE EMERGENCY BRAKE TO STOP THE TRUCK. THANK GOD I SURVIVED. UPON INSPECTION OF MY REAR BRAKE HOSES IT SEEMS THE LEFT BLEW COMPLETELY CAUSING THE SERIOUS ISSUE. THE WARNING LIGHT NEVER CAME ON. IF I WAS GOING AT A HIGH RATE OF SPEED THEIR WOULD HAVE BEEN NO QUESTION 2 OR MORE FATALITIES. *TR
