hello , I have a 1939 2.5 ton Chevy truck , original Bendix brakes on the front , I installed a check valve in the brake lines 10 lbs one for the right and one for the left . I adjusted the brakes evenly when I step on the brakes with a good solid pedal , the wheels stop equally however the left wheel does not release . I replaced the valve with a new one and the same problem , if I bleed the left wheel cylinder the wheel will turn freely. the system has new end cylinder , brake lines , brake shoes and hoses . any suggestions ? thank you 1pette1
