cause of problem :

i am not sure but i think it is because i once my car spun ount and my wheels were in full lock (left) and hit a footpath. chipped my rim etc.

what could it be ?

Hey mate, this sounds very similar 2 having warped disk which are the cause of brake shudder which have very similar symptoms as stated above...

to test this u can measure ur disks in 4 different spots around the disk 2 see if it is equally warn...

but this also seems 2 sound like the affect of ABS (i dont know if ur car is equipped with ABS) but if it is, this could be what this shuddering/shacking and that faint noise is....
basically the ABS system is locking and then unlocking the brakes very quickly preventing them from locking up... - i experience going down the straight at wakefield at 150km/h and putting the anchors on after the kink...

hope this information has helped
