denongtDoes anyone know what kind of msater cylinder bigger than 22mm that bolt on original booster of Corrado 1990
The 89-91 Audi 200 Quattro (some other models also) has a 25.4MM NON ABS master cylinder.
This is what I have in my car. Expensive if purchased new, but needed with the Porsche or Wilwood brakes. They can be found rebuilt for about $100.
