WE DO NOT FEEL THAT THE INSTRUMENT PANEL CLUSTER ON OUR MOTORHOME HAS EVER BEEN LARGE ENOUGH OR CLEAR ENOUGH FOR EASY READING. WE HAVE ALWAYS BEEN UNHAPPY WITH THE VISIBILITY AND JUST RECENTLY THE TRANSMISSION INDICATORS FOR 3 AND 1 GEAR HAVE FADED COMPLETELY. AT PRESENT WE HAVE AN APPOINTMENT TO GET THE PANEL REPLACED. *TR

ON 9/6/07, THE L.F. BRAKE ON MY MOTORHOME SEIZED UP AND OVERHEATED THE BRAKE ROTOR FOR ALMOST 10 MILES UNTIL I NOTICED SEVERE SHAKING IN THE STEERING WHEEL & SMELLED "BURNT BRAKE LINING" WHEN I STOPPED. I WAS DRIVING IN NORMAL CITY TRAFFIC NEAR ALLIANCE, OHIO; -NOT EXCESSIVE STOP AND GO, BUT THERE WAS MAYBE 4 RED LIGHTS OVER THE COURSE OF 3 MILES DISTANCE (AT 30 MPH) TO STOP. MY STOPPING WAS "NORMAL", NOT SUDDEN OR ERRATIC. THE LEFT FRONT HUB & WHEEL GOT SO HOT FROM THE CALIPER/BRAKE ASSY. SEIZING THAT IT BOILED AWAY ALL OF THE 90W LUBE ON THE WHEEL BEARINGS AND BLEW OUT THE RUBBER PLUG ON THE LUBE SIGHT GLASS. I LET IT COOL DOWN FOR AN HOUR, THEN LOOKED AT THE INNER SIDE OF THE L.F. WHEEL TO SEE IF I'D HAVE TO LOOSEN/PRY AWAY THE SEIZED BRAKE PAD OR CALIPER ASSEMBLY. SURPRISE, THE BRAKE PADS WERE ALREADY SITTING BACK AWAY FROM THE ROTOR; -THE CALIPER HAD APPARENTLY RETRACTED BY ITSELF AFTER COOLING DOWN. I PROCEEDED SLOWLY TO THE CAMPGROUND, 5 MILES AWAY, AND MADE ARRANGEMENTS TO GET SOME 90W LUBE OIL. LUBE WAS REPLACED THE NEXT DAY AND THE WHEEL BEARINGS STILL FELT GOOD; ANOTHER SIGHT CAP SEAL WAS INSTALLED. ON 9/12/07, I TOOK THE COACH TO MAINLINE TRUCK & TRAILER (A WORKHORSE CHASSIS SERVICE DEALER) IN SOLON, OHIO, FOR SERVICE. IN A NUTSHELL, I ENDED UP PAYING $828.28 TO REPAIR THE DAMAGE AND SERVICE MY COACH FOR FUTURE "PEACE OF MIND". THE FOLLOWING WORK WAS PERFORMED: SERVICED ALL CALIPER SLIDE PINS, LUBE, & BOOTS ON ALL 4 WHEELS; CONFIRM CORRECT CALIPER OPERATION ON ALL 4; REPLACE ABS WHEEL SENSOR ON LEFT FRONT; RESET ABS WARNING LIGHT; INSPECT ALL 4 ROTORS FOR CRACKS; REPLACE LF WHEEL BEARING INNER SEAL; INSPECT LF BEARINGS; INSPECT REAR AXLE HUB SEALS; ETC. ON 9/18/08, AT 11,891 MILES, MY RIGHT FRONT BRAKE SEIZED UP UNEXPECTEDLY! THIS TIME ALONG A 45 MPH STATE HWY WITH VERY INFREQUENT BRAKING. I BELIEVE THE PROBLEM HERE IS FAULTY ABS CONTROLLER AND OR THE BOSCH BRAKES. THEY DO NOT ALWAYS RELEASE THE CALIPERS. WORKHORSE IGNORES THIS PROBLEM! *TR

THIS IS A BRAKE FAILURE ON ,MY 2004 ALLEGRO MOTORHOME BUILT ON A W-20 CHASSIS MANUFACTURED BY WORKJORSE CUSTOM CHASSIS. ON THE DATE IN QUESTION, THE RIGHT REAR BRAKE LOCKED UP AND OVERHEATED. THE LEFT REAR BRAKE OVERHEATED. THESE ACTIONS CAUSED REPLACEMENT OF THE RIGHT REAR CALIPER, ROTER, SEALS AND SLIDE PINS. THE CALIPER AND SLIDE PINS WERE REPLACED ON THE LEFT REAR BRAKE. THE CALIPERS AND SLIDE ON BOTH FRONT BRAKES WERE REPLACED DUE TO OVERHEATING. OLD PARTS ARE AVAILABLE FOR INSPECTION.
