The front air brake hose may contact the inner fender on the left and/or right sides of some trucks. In some instances, the brake hose may rub through, resulting in a loss of air pressure upon brake application. Consequence of defect: brake hose may rub through causing air pressure loss when brakes are applied and reduced braking ability. A reduction of braking ability at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.
Install new brake chamber support brackets, brake line elbows, and air brake hoses, as necessary.
Vehicle description: medium duty trucks equipped with tilt hoods, 7000# front axle and air brakes. System: front brake hose.
