It pushes down about an inch it sounds like it’s releasing air and that’s it but when you open the bleed nipple it pushes to the floor when I was bleeding the system but as soon as I finished it’s hard again

Hi all had the same issue with my Audi for the past 3 years now, break pedal locked up upon breaking and only the hand break would stop me. I’ve had a new turbo break servo and vacume pump done by a garage about a year and half ago but same issue has happened again it’s gone solid. The vacume seems to be working as you can hear it hissing the break system has been bled which did have some air in the system but when bleeding the system the break went soft but is now hard again has anyone had this issue before?

Could anyone shine some light on a problem i'm having please? I have a audi A3 2010, whilst driving i had to slam on the brakes because of an idiot driver in front. My break pedal went hard and now wont release, the brakes don't work very well and when i try to pump the pedal it sounds like its releasing air in the footwell. I'm thinking the vacuum pump?
