do you mean buzz or vibrate. dose you feel it through the steering wheel, if so i would say that your discs are warpped

If its a vibrating/droning noise,only from high speed,then yes,your disks are warped.I changed my disks & pads yesterday for the same reason,only took about 40 mins to do the lot.

It's not any form of ABS is it?

Can check by, under bonnet there should be a big alloy block with lots of brake pipes into it. Usualy in either of the front engine bay coners or around the brake master cylinder. Sorry I don'k know where exactaly but I'm a Citroen driver with regular suspension.

A buzzing, I think, has been attributed sometimes to a misbehaving doseur valve, I think. not sure if a Hydraflush could help here.
