Vented valve and brake system using same

A venting valve includes a bore lumen. An MC valve passage is in fluid communication with the bore lumen. A venting fluid passage is in fluid communication with the bore lumen at a location spaced from the MC valve passage. An SCA valve passage is in fluid communication with the bore lumen at a location between the MC valve passage and the venting fluid passage. A venting valve shuttle moves between first and second shuttle positions at least partially responsive to fluid pressure. Shifting of the venting valve shuttle toward the second shuttle position urges air from the bore lumen into the ambient space via the venting fluid passage.
