Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
THE SUPPORT BRACKET FOR THE RIGHT REAR BRAKE, AIR CHAMBER AND CROSS SHAFT BROKE OFF THE REAR AXLE HOUSING WHICH CAUSED THE CROSS SHAFT AND CHAMBER BRACKET TO BREAK. THIS ALLOWED THE RIGHT REAR BRAKE CHAMBER TO ROTATE UPWARD WHICH CAUSED IT TO WEDGE UNDER THE FRAME RAIL. UPON FURTHER INVESTIGATION IT WAS DISCOVERED THAT THE SUPPORT BRACKET WELDED ON THE LEFT REAR SIDE OF THE AXLE HOUSING WAS ALSO BROKEN AND WAS NOT SUPPORTING THE LEFT REAR BRAKE CHAMBER AND CROSS SHAFT ASSEMBLY. IN THE CONDITION IT WAS DISCOVERED THE RIGHT REAR BRAKE WAS NOT FUNCTIONAL. *TR

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
WE HAVE HAD ISSUES WITH THE FUEL FILTER HOUSINGS STARTING TO SEEP FUEL THROUGH THE HOUSING ASSEMBLIES IN THE MBE ENGINES. WE HAVE HAD TWO OTHER UNITS WITH THE SAME ISSUE THAT WE HAD TO HAVE REPAIRED AND WE HAVE ONE OTHER VEHICLE IN THE SHOP CURRENTLY WITH THE SAME ISSUE. THESE UNITS WILL START TO LEAK FUEL AND WILL DRAIN THE FILTER HOUSING OVERNIGHT LEAKING FUEL ON THE ENGINE AND THE GROUND, AND UNDER THE RIGHT CIRCUMSTANCES MAY BECOME A POSSIBLE FIRE HAZARD..WE THOUGHT IT MIGHT BE AN ISOLATED INCIDENT BUT AFTER FOUR INCIDENTS AND THE PART BEING BACKORDERED WE THINK THIS MAY BE A BIGGER PROBLEM. *TR
