Service brakes, air: supply: check valve

What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2018 Thomas Built Buses Saf-T-Liner EFX school buses. The check valve for the air brake system may not be plumbed correctly which can cause the primary air system to not be isolated from the secondary air system.
Risk
In the event of a rapid loss of air pressure in the secondary system, the incorrectly plumbed check valve can cause rapid air loss in both secondary and primary system, causing the parking brakes to activate suddenly. This will increase the risk of a crash.
Remedy
DTNA will notify owners, and dealers will inspect and repair the check valve as needed, free of charge. The recall began on August 12, 2018. Owners may contact DTNA customer service at 1‑800‑547‑0712. DTNA's number for this recall is FL-774.
