- Published by: NHTSA \(United States\)
- Campaign number: 85V113000
- Manufacturer: MACK TRUCKS, INCORPORATED
- Reported: 1985\-09\-17
- Owners notified: 1986\-02\-07
- Component: SERVICE BRAKES, AIR
- Units potentially affected: 5020

## What is wrong

THE DUAL DOUBLE CHECK VALVE MAY NOT RELEASE THE PROPER    AIR VOLUME TO THE BRAKE SYSTEM, CAUSING A SLIGHT TIMING DELAY BETWEEN THE        TRACTOR AND THE TRAILER BRAKE SYSTEM.                                                                                                                             CONSEQUENCES OF DEFECT: IF THE BRAKES ARE SUDDENLY APPLIED, THE TRAILER COULD    JACKKNIFE WITHOUT WARNING TO THE OPERATOR, WHICH COULD RESULT IN A VEHICLE       CRASH.


## The remedy

INSTALL TWO NEW SLEEVES IN THE DUAL DOUBLE CHECK VALVE WHICH  WILL INCREASE AIR FLOW.


## Notes

VEHICLE DESCRIPTION: HEAVY DUTY TRACTOR TRAILER COMBINATIONS. SYSTEM: BRAKES, TRACTOR TO TRAILER.
