Adjusting Brake Regulator Options

[bbrock]

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?

I didn't realize the Factory Manual had the procedure. That is sweet. May need to spring for a real factory manual one of these days.

For Bench you could basically use any old master cylinder and rig up the lines and gauges to get pressure into the system. You'll need some sort of fixture to get the mechanical advantage to push in the master cylinder.

You would want to keep the bench lines pretty close to actual length to account for pressure drop across the lines but honestly it will be negligible if the hydraulic pressure apply is slow. The flow restriction is substantially higher in a rapid apply panic stop situation.

I suspect the cost for two high pressure gauges with good accuracy plus miscellaneous tubing and fittings, plus fixture materials will be at least 1/2 the PMB cost but I haven't priced high pressure gauges lately and could be way off.

However since you just need a pressure set point, maybe PMB will do for less? Call them and see. However, their lead time may be an issue for you since you're already on to final assembly steps.

Bottom line, I've been watching your thread. You have the skills and the jack of all trades mindset to get it done if you want to do it yourself. The work you've done is awesome. I'd trust you before I trusted any random "brake shop" though. (IMG:style_emoticons/default/biggrin.gif)

Just a question of time and money and which one is more valued at the given moment.
