The defect
The exhaust port in the up position allows water to enter the air brake system, which can block the air brake system in freezing conditions.
The risk
Blockages in the air brake system can block the exhaustfrom the brake chambers after service brake application, causing the brakes todrag and possibly overheat on either side of the drive axles. This couldincrease stopping distance and result in a vehicle accident.
The remedy
Invert the brake valves so the exhaust ports are down.
