DEFECT #1 - SERVICE BRAKES, AIR:DISC:CHAMBER
Posted on: 1979-10-12

Consequently, no air would be delivered to the brake chambers normally supplied by this valve. This would result in a no brake condition on the affected axle(s). This failure would constitute a non-compliance to federal motor vehicle safety standard no. 121, air brake systems.
Consequence
