Spongy Brakes - Can anyone Help ?

I have an issue with my MK 3 Golf Td 1.9 - 'M' reg

Changed brakes all round & bleed nipples.

New fluid & pressure flushed with a pressure bleeder.

Replacement master cylinder.

New Vacuum cover with new valve.

New servo to vacuum pump pipe.

Haven't changed servo or rear brake balancer block on the rear axle beam (the one with 4 brake pipes going into it)

I've been around all brake pipe unions & tightened them up.

There are no leaks anywhere.

The brake fluid reservoir is always at the correct level.

The brake pedal is firm before start up

But slackens when pressed down to brake, way to much travel.

Initially after pressure bleeding the brake pedal was firm before & after starting the engine & I thought the issue was sorted.

Having not driven the car for a few days its gone slack again !

Its like its got a leak or letting in air somewhere ?

From reading other peoples VW MK 3 golf issues about this topic has anyone got to the ROOT of this problem ?

If so I would like to know please as this is getting to be a bit of a joke & I'm not spending any more money on the car, like changing the servo or balancer.
