Hi, i'm getting a clicking sound from the front brakes when applied and my brakes are also juddering which i think is down to warped discs. I think its the rear ones that might be warped because they are quite old and i haven't changed them since i've owned the supe and the discs on the front i only replace them about 6 months ago with 3g discs and endless pads. I've looked at the brakes and all the shims are still in place and the pistons and seals on all the brake calipers look ok and they move freely so there all ok and not seized or sticking, what else can i check for any ideas and where abouts are the abs sensors i might give them a clean up
