INTERMITTENT BRAKES (LOST BRAKES) ON FIFTH WHEEL DUE TO THE USE OF UNDERSIZE WIRE AND OVERUSE OF SCOTCHLOK GUILLOTINE CONNECTORS. EACH BRAKE HAS A MAXIMUM CURRENT DRAW OF 4AMPS. 4X4 = 16 AMP POSSIBLE DRAW ON 14 AWG WIRE AT APPROXIMATELY 60+ FOOT LOOP ROUND TRIP FROM PIN BOX TO BRAKES BACK TO PIN BOX. THIS IS AN EXTREMELY DANGEROUS SITUATION. THE BRAKE WIRING IS SUBSTANDARD IN EVERY CONCEIVABLE WAY. SHOULD BE AT LEAST CONNECTED 10AWG USING CRIMPED BUTT SPLICES AND CIRCLE CONNECTORS. IT WOULD ALSO HELP TO HAVE A GROUND BOND AT THE AXLE TO REDUCE THE LOOP BY 50%. SOMEDAY SOMEONE WILL DIE (PROBABLY HAVE ALREADY) BECAUSE OF CHEAP UNDERSIZED WIRE WITH CHEAP GUILLOTINE CONNECTORS EVERYWHERE. FOR LIGHTS OK FOR BRAKES? NEVER!*DT*JB

TWO SEPARATE ISSUES: 1. LIPPERT WHEEL BEARINGS LEAKED GREASE ALL OVER THE DRUM BRAKES WITH LESS THAN 4000 MILES. LIPPERT REFUSED TO PAY FOR REPAIRS BECAUSE IT HAS BEEN MORE THAN ONE YEAR. 2. WITH BRAND NEW BRAKES PROPERLY ADJUSTED, BRAKES ARE STILL VERY WEAK. APPLYING 12 VOLTS FROM BRAKE CONTROLLER RESULTS IN MINIMAL BRAKING. SUSPECT UNDERSIZED FINAL WIRING TO BRAKES (20 GAUGE). BRAKES HAVE BEEN UNDERPERFORMING SINCE DAY 1. *DT*JB*DT*JB

THE BRAKES, SEALS AND BEARINGS ON MY 5TH WHEEL TRAVEL TRAILER WILL HAVE TO BE REPLACED FOR THE THIRD TIME DUE TO THE SEALS LEAKING GREASE ONTO THE BRAKES. ALL FOUR BACKING PLATES, THE FRONT TWO HUBS AND ALL FOUR GREASE SEALS AND BEARINGS WERE REPLACED ON OUR FIRST TRIP AFTER TAKING POSSESSION OF THE FIFTH WHEEL IN MAY 2017. THIS WAS DONE AT A CAMPING WORLD DEALERSHIP IN NORTH CAROLINA AND RESULTED IN BEING WITHOUT THE USE OF OUR TRAILER FROM MAY 18 ' 23. ON OUR SECOND TRIP, STARTING ON JULY 9, 2017, THE BRAKES AGAIN BEGAN PERFORMING POORLY. RAY DUFFY, OF GRAND DESIGN, ARRANGED TO HAVE THEM INSPECTED IN WEST YELLOWSTONE, MONTANA ON JULY 14, 2017 AT JAKE'S AUTOMOTIVE. HE PRE-SHIPPED REPLACEMENT PARTS IN ANTICIPATION OF BAD SEALS. THE TECHNICIAN AT JAKE'S AUTOMOTIVE FOUND GREASE CONTAMINATION ON THE RIGHT FRONT, RIGHT REAR AND LEFT REAR BRAKES. HE ALSO FOUND THAT THOSE SEALS AND BEARINGS HAD SEPARATED FROM THE HUBS AND REMAINED ON THE SPINDLE WHEN THE HUBS WERE REMOVED. THE RECEIPT STATES, 'HAD TO REPLACE 3 OF FOUR BACKING PLATES AND HARDWARE DUE TO WHEEL SEALS BLOWING OUT.' THE FOURTH WHEEL, THE LEFT FRONT, WAS NOT REMOVED OR INSPECTED BY THE REPAIR FACILITY SINCE THEY DID NOT HAVE REPLACEMENT PARTS AVAILABLE AND THEY WERE CONCERNED THAT REMOVAL OF THE WHEEL COULD DAMAGE THE GREASE SEAL. I REMOVED ALL FOUR HUBS TODAY. THE INTERIORS OF THE TWO LEFT HUBS WERE COMPLETELY COATED WITH GREASE. THE LEFT FRONT WAS WORSE THAN THE LEFT REAR. THE TWO RIGHT HUBS DID NOT HAVE AS MUCH GREASE ON THEM AND WERE EVIDENTLY DOING THE MAJORITY OF THE BRAKING. THE INSIDE OF BOTH HUBS WERE PRETTY SEVERELY SCORED BY THE MAGNETS AND NEED TO BE REPLACED. ALL FOUR GREASE SEALS AND THE INNER BEARINGS STAYED ON THE SPINDLES WHEN THE HUBS WERE REMOVED. SINCE THE SEALS ARE SUPPOSED TO BE PRESSED IN, I FOUND THEIR REMAINING ON THE SPINDLES PROBLEMATIC.

BRAKES WERE NOT WORKING VERY WELL, WITH THE TRAILER BRAKE CONTROLLER GAIN IN MY TRUCK SET AT 10.0 (FULL ON). PROBLEM WAS CAUSED BY LEAKING AXLE SEALS ON THE PASSENGER SIDE OF THE VEHICLE WHICH RESULTED IN THE BRAKE SHOES AND DRUMS BEING COATED WITH AXLE GREASE. ALL FOUR BRAKE ASSEMBLIES AND AXLE SEALS WERE REPLACED BY THE DEALER UNDER WARRANTY.

THE AXLES/BRAKE ASSEMBLIES HAD DEFECTIVE INTERIOR SEALS. THE SEALS FAILED AND CONTAMINATED THREE OUT OF FOUR BRAKES WITH GREASE. THIS NEARLY CAUSED ME TO HAVE A SERIOUS ACCIDENT DUE TO UNABLE TO STOP THE TRAILER TO AVOID VEHICLE THAT PULLED OUT IN FRONT OF ME. I HAD TO RUN OFF ROAD TO AVOID ACCIDENT. THIS IS A KNOW ISSUE WITH LIPPERT COMPONENTS THAT THEY CONTINUE TO TRY TO DENY. I ATTACHED TWO PHOTOS OF WHAT I FOUND IN THREE OUT OF FOUR BRAKE HUBS UPON INSPECTION.

AXLE SEAL LEAKED CAUSING GREASE TO LEAK ONTO BRAKE FRICTION SURFACE, GREATLY REDUCING BRAKING ABILITY. PROBLEM WAS FOUND DURING OWNERS SELF INSPECTION. THIS PROBLEM WAS BROUGHT TO MY ATTENTION FROM THE GRAND DESIGN OWNERS FORUM. "HTTP://WWW.GRANDDESIGNOWNERS.COM/FORUM/SHOWTHREAD.PHP/8531-POLL-HOW-MANY-OF-YOU-HAVE-HAD-YOUR-GREASE-SEALS-FAIL "
