my only addition to your situation is if you elect to power bleed you have 2 choices: push or pull

you can build or buy a power bleeder which attaches to the master cylinder and pushes fluid under modest pressure through the system . the old expelled at the bleeder nuts.

or you can pull the fluid out the bleeder nuts into a bottle using a vacuum while having a passive refill bottle attached to and above the MC feeding fresh fluid into it.

i can say with experience having built my own push bleeder which worked perfectly this method is simple and direct.

recently i had to diagnose a brake booster leak on one of my girls cars. to do this i bought a mityvac at harborfreight for 37 dollars.

i found this tool will also with touch of a nob also become a pressurizer as well.

this tool is imo in-dispensible for all home mechanics.

to make a long story short using it to bleed brakes is much easier and safer than pressurizing the MC. because you are with the tool and source of power on you brake system at each point and the MC is only being "passively" refilled as fluid is pulled out you have much better finesse and control over the process using vacuum.

any way my 2 cents

and mityvac makes a great tool and it is cheap for what it can do.
