NHTSA recall 85V147000
Service brakes, hydraulic › Foundation components › Hoses, lines/piping, and fittings
Grumman Kurbmaster
The defect
The routing of brake lines brought the line close to an area used to fasten the seat socket support structure to the chassis. The fastening of seat support IS done with bolts and when the bolts are tightened the free end of the bolts pinches one of the brake lines against the chassis frame rail. This causes a reduction in the brake line which reduces the volume of fluid passing through the line. consequence of defect: the reduced volume of fluid affects the efficiency of the brake system. Also the brake line may crack causing loss of fluid line . In either case, a longer stopping distance would be required when maximum brake efficiency IS needed. Operation of a vehicle with damaged brakes could lead to a vehicle crash.
The remedy
Inspect and replace the affected brake line with a new part.
