I have long since replaced mine with the mechanical switch that works flawlessly but still have the garbage switch plumbed in the front brake circuit. All has been fine until I lost brake pressure recently. I thought there was a leak at the MC or Servo (replaced 18mos ago), but low and behold it was leaking at the brake switch, actually coming out of the top where the wire connectors are. So not only do these switches not work, they are also prone to leaking. Quality at its poorest. At this point I would just like to put something in there to block it off rather than just putting another switch in there. Does anyone know of a cap you an just put there or do I need to just buy another crappy switch to plug it. Thanks for any info.
