95 80 series. Got a question on brake pedal sinking to floor. I have replaced master cylinder and all soft brake lines with OEM parts. New pads and rotors. Also deleted ABS and LSPV. Bench bled the master and bled the brakes using the two person method as well as using a power bleeder set to 10 PSI. I have gone through around a gallon of brake fluid and can see no bubbles while cracking a bleed valve. After pumping up the brakes with the engine running the pedal still sinks slowly almost all the way to the floor. It stops maybe an inch or two above the carpet. Rig stops fine and can lock up the tires. My question is, after researching on here it’s been mentioned a few times to stick a block of wood under the pedal to prevent the master from moving too far and blowing out a seal. I wasn’t aware of this when I bled the brakes the first time. Is this necessary on a brand new master as well? No mention of it in my FSM. Or could it possibly just be air is still stuck in the system?
Edit: brake booster was replaced last year with a Seiken one and tests OK.
Thanks
