NHTSA recall 90V027000
Service brakes, air › Antilock
Strick Trailer
The defect
An incorrect ratio relay valve was installed in the brake system and the pressure protection valve was installed incorrectly.
The risk
Incorrect installation of the valves would reduce the available reservoir capacity by one half, resulting in loss of normal braking function and could cause application of the spring brakes, which could effect the operation of the truck and result in an accident.
The remedy
Replace the brake relay valve and re-orient the pressure protection valve.
