Hey guys hoping someone out there can help

i have a 90 8v gti everything is fine with the car apart from my brakes. after a while they get very spongey and get worse and worse, its been in the garage a few times and there is always air in the system, it has braided hoses on and the master cylinder has just been changed
anyone got any ideas why there wud be air in the system?
any help is much appreciated

Thanks

Hi gavharris, did you get to the bottom of the air leak? Mine's doing exactly the same thing!

I've got a new MC and rear pipes. I'm wondering if it's the rear bias vale.

Thanks
