    Hi,

    Just a quick question

    If I upgarde my A4 1.8T Quattro brakes to RS4 (B5) disc's, pads and calipers, will I have to upgarde the brake servo and master cylinder.?

    Thanks in advance for any help.

    ive put the S4 321mm set up on mine, didnt bother with the servo/master cylinder, but you may need spacers

    No servo or master cylinder upgrade needed but like scott says, you may need spacers depending on what wheels you are running.

    As above.

    The wheel choice is the important one due to the offet and spoke shape.

    You might need the brake lines too but no need to upgrade the brake servo but 18" wheels will be needed.
