PACCAR Incorporated
The problem
THE REAR BRAKES MAY NOT RELEASE AS QUICKLY AS SPECIFICATIONS REQUIRE. CERTAIN TRUCKS WERE EQUIPPED WITH AN INCORRECT SIZE AIR BRAKE LINE INSTALLED BETWEEN THE REAR BRAKE RELAY VALVE AND THE AXLE TEE FITTING. THE CONDITION IS NOT IN COMPLIANCE WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD 121, "AIR BRAKE SYSTEMS".
What owners should do
THE DEALER WILL REPLACE ANY INCORRECTLY SIZED HOSES WITH THE CORRECT PART AT NO CHARGE.
