hey guys fitted my new ktech brake disks and green stuff pads last month. Whilst out the other day i noticed a vibrating sensation coming from the front right whilst under light braking. It doesnt happen all the time but is quite regular. I took the wheel off at the weekend to have a closer look and the brakes look fine. Can anyone help and explain the possible problem. I have a service next week and don't want renualt to try and sell me new pads if i don't need them. Help appreciated
