ray,
it's gonna get even worse - have your alfa in for servicing ASAP!
the problem is either with the hose feeding the clutch pump with
hydraulic fluid or the pump itself.
it might be that the hose rubber seals are all worn out and its feeding
the clutch pump with air as well - that shouldn't be happening at all!
had absolutely the same prob with my 156 1.8ts - and it was the hose!
fairly inexpensive and easy to replace.
good luck!

Hi

Can't offer you any specific help but there is a forum in the UK dedicated
to the 155.
It is at www.alfa155.org and anyone from any country is welcome. I am sure
someone will have suffered the same problem and will be able to help you
out.

Hi Ray,
It sounds like you have got air into the system, check the brake fluid
reservoir, to make sure it has enough fluid, if it has got too low you
could have pulled air into the when for instance, while cornering and
braking at the same time. Or,if you have pressed the pedal a couple of
times while standing on a hill.
It is not a big job to bleed brakes, and a good mechanic would do the
job in 1/2 an hour. Mind you if your fluid is low, you should check
why it is low. Check below the master cylinder for leaks, and the
slave cylinder, then check each caliper. These checks you could do
before handing the car to a garage, then they cannot say they have
changed parts that are OK.

Hi again Ray,
Sorry about talking about your brakes, I realised later you wanted
info on your clutch. As it happens the same checks go for the clutch,
you only need to check the master cylinder, then the slave cylinder
for leaks. Bleeding these only takes minutes for any garage.
