Technical Sedici 1..9 Elegnza Diesel 2006 Spongy break pedal

[Des999]

Hi all I've got a Sedici Eleganza 1.9 Diesel 2006 with a spongy break pedal. I've had it looked at by 4 different mechanics and they keep saying its supposed to travel to the floor like that. I've had it for five years and it didn't do it till about April this year. When you need to brake you have to pump the brake pedal to get any pressure in the system.
Apparently the discs and pads are good and the rear brake shoes have plenty of meat left on them. The brake fluid is not leaking from master or wheel cylinders and the brake pipes show no breaks in them.
The system has been bled twice but the problem's still there.
Any ideas guys what it might be? Any suggestions much appreciated.

Ah car has rear brake drums and shoes.......
If brake shoe adjusters no longer adjusting for wear that causes long brake pedal stroke

Years ago on my classic mini I used to drive with the handbrake on a click or two when the rear brakes were out of adjustment and that used to reduce pedal travel significantly. I wonder if the op could try this to see if it reduces travel in this instance? If so then that’d be the answer you would think
