bleeding brake master?
So I changed the brake line from the master to the PValve, so the master was completely empty when I did this(rear brakes line) not the front portion of the master it was still full. So we tried bleeding the rear brakes but no fluid is getting back there. Do I need to bench bleed this thing? If so is there a good way to do it on the truck? Or should I just pull it off?

1. Disconnect the brake lines at the master cylinder
2. Install flexible brake lines or prefabed brake lines that curl up and back into the reservoir
3. Fill reservoir with brake fluid so that the end of the lines are submerged
4. Have a friend pump brake pedal while you watch air bubbles being deposited into reservoir
5. When bubbles no longer appear, have assistant stop pumping brakes.
6. Disconnect flex/fabbed tubes and ensure no air enters system
7. reinstall brake lines and bleed lines
Hope that helps

I understand that. JUst wondering how to bench bleed without removing the master. Also if I bench bleed on the truck do I put the pedal all the way to the floor like we do when bleeding the brakes. Thanks.

Yes, give it all shes got, you want to squeeze every bit of air out of the MC plunger. Also remember that when bleeding the brake lines you have to bypass, I use small vice grips to pull the plunger, the proportioning valve. Ford makes a clip but I have yet to own one.

I have been driving the truck a bit now and really like the braking action I have vs. the old action. Old was lots of muscle work with the right leg and that is now gone. It is more like a power disc brake feel even though it is all drums and of course needs more distance to stop with the drums. So naturally I am not liking when a red light changes right at that critical moment when you can't quite go through the yellow and so you have to hit your brakes. So when that happens, like twice last night, the voice inside my head says "come on baby you can do it." Although I was tempted since with the now 390 and 3,25 gears the truck has a lot of punch when you step on it. Moves fast, stops slow, a great combination.
I used it last night to pick up my son from what would be considered his first school dance in 8th grade. At Alamo all cars will be Teslas, Escalades, Yukons, and so forth. I pull into the line with the low rumble from my truck to get my son and the kids around him point and start to ask him. Yeah, this is a "truck" and all the rest of you are imposters.
