Brake Failure Warning When Turning Right?

Hi was wondering if anybody has had this problem before or know what it could be before I take to garage for a diagnostic check.



When applying the brakes before turning right at a junction or roundabout the "BRAKE FAILURE" warning has started appearing on the dash the an audible beep. The ABS warning doesn't appear though so I'm rather confused on what it could be.

My car doesn't have any brake pad sensor attached or anything like that so any help on this matter would be great.



Thanks David
