DEFECT #3 - SERVICE BRAKES, AIR
Posted on: 1993-04-30
Description
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.
Consequence
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.
Corrective Action
Invert the brake valves so the exhaust ports are down.
Notes
System: brakes.vehicle description: heavy trucks with traction control that have crossmembermounted brake valves positioned with the exhaust port up.
