Well my brother is still fighting the battle of getting his GTV reliable. It now has an awesome engine thanks to Claude, new exhaust system, and he has had the brakes upgraded to Brembos on the front, the rears rebuilt, master and booster. Unfortunately the booster is kaput and the third one that my brother just bought is stuffed too. The brake guys up here don't want to touch them and even if they did it could end up like his previous 'rebuilt' one. An expensive exercise.
So does anyone have a recently removed booster that worked well?
