The 1990 Ford L8000 has two recalls, the more serious being a faulty air brake check valve that can allow pressure to bleed between brake reservoirs, potentially causing partial or complete brake failure.
If the primary air supply loses pressure, a correctly functioning check valve should isolate the secondary reservoir and preserve enough pressure to stop the vehicle. With this defect, that isolation can fail and pressure equalizes across both reservoirs, leaving the driver with reduced or no braking ability. The second recall is a compliance issue related to tire and rim selection labeling requirements, with no reported risk of physical failure.
