Brake indicator switch rebuild

Recommended Posts

Well I got it... After a full day of heating and working at it, I figured it out.


I tried going at it with compressed air but that had no effect.


My next to last Idea was to attack it with the grease gun. Napa has 10x1.00mm grease zerks (part number 715-2008) that I was able to mount on the ends. after attaching the grease gun to it and pumping it a few times, the plunger shifted. After that, I applied the blow torch and continued to pump with the grease gun until the end popped out sending burnt grease everywhere.


it is now going to soak in the cleaner overnight again and tomorrow, I will clean up the bore and hopefully replace the seals.

I know this thread is a little old, but where did you get the rebuild seals for this? I thought it was NLA. I have a Wilwood combo prop valve I was going to use since I thought you couldn't get this anymore. Anyone know if those seals are still available somewhere. I looked here and google'd but never saw anything.

I went back and looked. The only O-rings I bought at the time was the Dorman O-ring kit of like 10 different sizes. I assume I matched up the sizes as close as I could get. I know that's probably not what you wanted to hear but that's all I can think of. Make sure its the epdm type rubber as the other stuff will melt away.
