ABS Delete & Permanently Soft Pedal

[Malleus]

My DD recently lost its OEM booster @ 300k miles.

Would air in the system still give me a firm pedal with the truck off? That's what's confusing me.

I did bleed the MC per the FSM, but I'm not sure that method is really all that effective (lines off, gently press in brake pedal, hold fingers over the holes in the MC and release the brake).

when motor is not running will get a few pumps on the pedal until vacuum is gone. then a hard pedal.
the first thing you need to do is make 100-percent sure your MC is purged. do a 'bench bleed' on the truck before bleeding the lines.

I’ve already done all that. Fresh calipers & ABS/load valve delete in the original build.

Still chasing soft pedal.

Have you considered going hydroboost?

I can lock all 4 tires.

Being a manual transmission truck and avoiding cities, I don't even use my brakes all that much. Lol. And honestly, I have a lot of other things on this truck that I would upgrade before that. Especially at what I'm seeing kits running.

I have now properly bled the MC. I re-bled the lines again. Same brakes I've always had.

Which I guess leaves me at something being up with the booster? Anything else I can look at/test?
