1989 963 breaks stuck on pt2

I recently posted about having my 963 not be able to move due to breaks potentially being stuck on, since then I’ve moved the break spool to “max speed position” with a 5/16 bolt, with no change, I’ve checked charge pump pressure and it’s hard to read on my gauge but static it shows 150 ish psi and then I’m getting pretty well 0 on my break pressure tap when I go into forwards or backwards travel. And my travel motors are getting 2500ish psi. So my question is, do I need to be looking for a screen that is potentially clogged, or am I looking at a potential charge pump issue? I also noted a “u tube” in the machine manual which my machine doesn’t have (pictured below is what’s there instead) just looking for some guidance going forward and where I need to look next. Also I attached a photo of the frame at my rear bumper I have developed a hydraulic leak of some kind near my front bumper and I have no idea where it could be coming from, not sure if this is a related issue, but it just started during my testing on the machine, any input is appreciated thankyou

another thing for you to check make sure the brake lever (where the 5/16 bolt goes) make sure the key is in the keyway and not in the slot where the clamp bolt is
