i was just wondering is there more then 1 possible cause for the ever common break shudder on BA's or is it just the s**t brake discs?

if its just the discs ill start saving for DBA's (was gonna upgrade later down the track but brake shudder gives me the s**t)

There are many causes other than the discs.

Most of the time, its not the discs' fault at at all, but from other parts around it, or fitment issues.
