I just finished rebuilding my brake regulator with the PMB DIY rebuild kit and it looks like new. Only thing left is to set the switch to 525 psi. I'm guessing I could send it to PMB to have them set it, but wondering if this could be done locally at a brake shop. Anyone know?

@bbrock Brent, I just came across this thread. FYI, as more datum, below is a pic of my pressure regulator (that has probably never been adjusted, and certainly hasn't been adjusted for 35 years) and the adjuster appears to be at about 11mm.

Good info. I should have measured mine before I took it apart. (IMG:style_emoticons/default/beerchug.gif) |

I just rebuilt mine with the PMB kit. Access with engine in and on jack stands leaves a fair bit to be desired.
Even after having bled my brake 3 times this summer, there was still crap in the regulator even as lines bled perfectly clear. Part of it likely was moisture given some of the small areas of pitting on the plunger. (IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-14731-1710450236.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-14731-1710450237.2.jpg) It is amazing how tight the scraper seal is. It was a major PITA to install. We'll see if any pedal pressure changes in a few weeks when it's back on the road. |
