audi s2 brake master cylinder

[peter_jensen]

Hello

Need help to my break issue.

Starting my first summer run the break did go crazy.

It is like it is brakning all the time so not releasing the brake pads.

If i press the brake paddel a little it release pads a small amount.

i replaced the bomb with a new one last summer.

Could it be the master cylinder that is leaking?

anyone has the part number of the master cylinder and where to by it.

I am grateful for any help

Thank you

Audi s2 1991
