TL* THE CONTACT OWNS A 2002 CHEVROLET SILVERADO 2500 HD. WHILE APPROACHING A STOP SIGN THE CONTACT DEPRESSED THE BRAKE PEDAL BUT THE BRAKES WOULD NOT RESPOND AND THE PEDAL WENT ALL THE WAY TO THE FLOOR. THE CONTACT WAS ABLE TO STOP THE VEHICLE BY APPLYING EXCESSIVE FORCE. THE CONTACT INSPECTED THE VEHICLE AND NOTICED THAT THE BRAKE LINES WERE CORRODED, FRACTURED AND LEAKING.

I WAS DRIVING SOUTH ON MD-235 IN LEXINGTON PARK, MD WHEN THE LIGHT AT THE INTERSECTION OF MD-235 & FDR BLVD. TURNED YELLOW. I HAD LITTLE ROOM TO STOP AND APPLIED THE BRAKES FORCEFULLY, SLOWING TO APPROXIMATELY 25 MPH WHEN THE PEDAL WENT TO THE FLOOR AND I RAN THROUGH THE INTERSECTION AS THE LIGHT TURNED RED. NO CARS WERE IN FRONT OF ME; AN ACCIDENT DID NOT OCCUR. I USED THE EMERGENCY BRAKE TO STOP AND OPENED THE HOOD, THINKING I HAD A BRAKE MASTER CYLINDER FAILURE. I NOTED FLUID DRIPPING FROM UNDERNEATH THE CHASSIS BY THE DRIVER'S DOOR, & ON FURTHER INSPECTION, FOUND A RUPTURE IN A CORRODED BRAKE LINE. I DROVE HOME USING THE EMERGENCY BRAKE (RURAL AREA; APPROXIMATELY 12 MILES), LIGHTLY PRESSING THE BRAKE PEDAL WHEN STOPPING WITH THE EMERGENCY BRAKE TO TURN THE BRAKE LIGHTS ON. ONCE HOME, I FOUND VIRTUALLY EVERY STEEL BRAKE LINE THROUGHOUT THE VEHICLE BADLY CORRODED. AN INTERNET SEARCH PROVIDED INFORMATION THAT THIS IS A PREVAILING PROBLEM WITH 1999-2004 CHEVROLET TRUCKS OF ALL MODELS. A PROBLEM THIS PREVALENT WITH THIS HIGH OF A SAFETY CONCERN NEEDS A MANUFACTURER'S RECALL ISSUED FOR THESE VEHICLES. I AM THE SECOND OWNER OF THIS VEHICLE. *TR
WHILE COMING TO A RED LIGHT, I LOST THE ABILITY TO STOP. UPON INSPECTION I OBSERVED SEVERELY CORRODED AND RUSTY BRAKE LINES AND FLUID LEAKING FROM ONE OF THE BRAKE LINES. *TR

WAS DRIVING ON ROAD WHEN DRIVER PULLED IN FRONT OF ME, I HAD TO A QUICKLY APPLIED BRAKES TO SLOW DOWN. WHEN PUSHED DOWN THE BRAKE PEDAL JUST WENT SOFT AND MUSHED DOWN. NO BRAKING ABILITY WAS POSSIBLE. HAD TO SWERVE INTO ON COMING TRAFFIC TO AVOID MAJOR COLLISION. OTHER CARS SWERVED OUT OF MY WAY. ~300 YARD DOWN THE ROAD THE TRUCK FINALLY CAME TO ROLLING STOP USING LOWER GEAR AUTO TRANSMISSION TO SLOW TRUCK DOWN. AFTER STOPPING SAW BRAKE FLUID POUR OUT OF FRONT ENGINE COMPARTMENT. UPON RETURN HOME SAW NO SIGN OF LEAKS IN DRIVEWAY. ALSO THERE WAS NOT VISIBLE LOSS OF BRAKE FLUIDS LEVEL NOR SOFTENING OF BRAKE PEDAL PRIOR TO THIS SUDDEN AND COMPLETE LOSS BAKES. FLUIDS ARE CHECKED ATLEAST MONTHLY. SO BRAKE LINE OR LINES RUPTURED SUDDENLY WITHOUT WARNING. THE POTENTIAL FOR DISASTER IS HUGE. THE HYDRAULIC BRAKE LINES APPEAR TO HAVE TO THINNED OUT FROM EXCESSIVE CORROSION AND THEN BURST (NOT LEAK) WHEN HEAVY BRAKE PRESSURE IS APPLIED WHICH IS THE WORST TIME FOR BRAKES TO FAIL. THIS IS PERSONAL USE VEHICLE NOT USED FOR COMMERCIAL WORK. HOWEVER IT IS DRIVEN AND USED IN THE SNOW BELT IN THE WINTER. IF YOU OWN ONE OF THESE TRUCKS AND LIVE IN THE SNOW BELT COMPLETELY INSPECT REPLACE YOUR LINES BEFORE SOMEONE DIES. FAILURE POINT WAS IN FRONT AREA UNDER HOOD NEAR LEFT WHEEL RIGHT ON BRACKET WHERE 4 LINES BEND. THESE ARE LARGE VEHICLES AND THE FAILURE GAVE NO OBVIOUS WARNING SIGNS PRIOR TO FAILURE. *TR
A BRAKE LINE RUSTED THROUGH IN THE FRONT OF THE TRUCK. AFTER LOOKING UNDER THE TRUCK, I FOUND THAT ALL THE BRAKE LINES ARE SEVERELY RUSTED AND LOOK AS IF THEY WILL FAIL AT ANY TIME. ALL BRAKE LINES WILL HAVE TO BE REPLACED BEFORE THIS VEHICLE IS SAFE TO DRIVE AGAIN. AFTER CHECKING ON THE WEB I HAVE FOUND THOUSANDS OF OTHER C…
