As heavy duty diesel truck parts, foot valves ordinarily meter compressed air from the operatorâs pedal control into the vehicleâs air-brake system, directing delivery pressure to the braking circuit. These port dimensions and the three-hole mounting pattern provide useful details when comparing the valve with the existing component. MACK lists 745-286171 as the OEM reference; selected Bendix cross-references are 286171 and 286171N.
