check the vacuum pipe from brake servo to inlet manifold for breaks/perished and is fitted with a one way valve which may be faulty

Also worth gently touching each wheel hub in case it is a sticky caliper.  If it is then one wheel will be warmer than the rest.  This is the symptom on my X6 - solid pedal sometimes and front right wheel warmer than the rest.  You might also get steering vibration, but not always.

New (remanufactured via Pagid) caliper here, just waiting time and weather to do it.  I’ll probably replace front discs and pads at the same time.

If you have done what has already been suggested then you might try replacing the rubber pipes between servo and inlet, they could be collapsing on the inside
