Alright, my brake issues all started with my rear brakes not bleeding, and we found the need for the bleeding tool on the prop valve. Then, the MC still would barely bleed bc it seemed that it just wouldn’t push enough fluid. Now, I have a 99 3500 MC and the brakes bled great, they do well on the road but they can’t hold the truck on a steep grade. My driveway is pretty steep and it will just roll down with the brake pedal slammed. I remember when bench bleeding this MC the piston seemed to travel further than the others. When holding the brakes the pedal does not hit the floor but it does feel like it hits a hard stop. Not spongy feeling. This is all new lines, a basically gutted disc/disc prop valve, new MC.
