11000 miles for discs is rubbish. I doubt you need them that soon. My VTS gets harsh braking but Im only about to replace them on 37k miles. (Ive had it since 24k but as far as I know theyve not been replaced, but even then thats 13000 of hard braking.
I took it to Kwikfit last year when they were squealing (but I wantred them to check the general condition too), he said Id only stop that with new discs and pads but I needed them anyway. I took it to another garage and he told me that was crap and just told me to get some copper grease and smear it all over the backs (non friction surface) of the pads and that sorted it, did it myself.
