I would still change that valve just because.

Even with test vehicles that had fluid changed out regularly, occasionally we would still get a valve that would hang up on us after a few years of service.

Glazing is not a characteristic of light use as frequently thought of, it is from quick high heat events where the organics deep in the friction compound that haven't had the chance to normally carbonize in use vaporize and solidify on the running surface. I.E., if the rear brakes are not working, you have a better chance of glazing front brake pads then when everything is working normally.

 

Guys, I'm having no luck finding a PN & Part for the F350 combination valve. . .

Anyone have any suppliers up their sleeves?
Thanks!

 

Just want to say I'm a idiot and thx for the thread it was a life saver ended up replacing ,y entire brake system less the pro valve and it was that dam plunger lol Thx again!!!

 

Many thanks for this thread!! The Vac Booster plunger was adjusted too short by 1/4 inch on mine too. I adjusted it out and Yahhoo!!! now I can stop the dang thang!!



This Thread saved me many hours of frustration. Many thanks to posters, and Mad Scientist experimenters. You guys are wonderfully appreciated.
