Brakes

I'd rule out the P-valve till last, they seldom mess up.

I'm going with the possible "internal leak" (fluid leaking past the plunger/ o-rings in the bore) in the master cylinder

Bench bleeding is a challenge on the bench- I do it on the vehicle (takes 2 folks but works fast!)

This 1st video may show the process that needs to happen/ couple it with the 2nd video (a little cruder video) You'll see how much EZier I think it is.

Here's the actual "on vehicle" process

Success, everything is copacetic.
Murphy only reared his ugly head twice.

Thanks for your help, Tom

Just for giggles

Did any of that help? Or did you go another route?

If so, what was most beneficial?

The Medic

Bleeding the master on the truck was a big help since there were two of us. Only took maybe 25-30 strokes. The idiots at autozone were almost no help at all. The bleeder kit consisted of two plugs. Once master was bled did have to bleed all 4 wheels 5 times to get all the air out. Did it in order every time.

Thanks again

So now,

Looks like you owe me lunch!

8 Krystal Burgers and a Coke would probably do it!

LOL!

Glad you got it and I was able to help somewhat,

Send your pals here too, we've got many fellers that know their stuff answering questions!
