Set the emergency brake on hard, pump up the foot brake, then release, - try and see if you still have excessive pedal.
If the pedal is higher, you need to re-adjust your rear brakes .
First thing I did.
Since I had to take the system apart to change any of the suspected parts I just replaced all the wear items. Flush & bleed once.
~$200 to potentially save a life and give me peace of mind!
