Reg Evans Posted July 9, 2018 Report Share Posted July 9, 2018 The port that feeds the switch must be plugged. 1 Quote Link to comment Share on other sites More sharing options...
JBNeal Posted July 9, 2018 Report Share Posted July 9, 2018 Yep, kinda sounds like lack of brake fluid flow is not activating the pressure switch...brake line could be removed to drain fluid and clean out port then remove contamination without removing from the chassis...or possibly rig up line from switch port that drains back into reservoir for quick check of fluid flow after poking that port with a drill bit by hand then flushing master cylinder before re-attaching brake line...there are several ways to skin a cat here...
