so my front break is acting weird. On my triumph when i use the front brake everything is super smooth even when breaking hard at high speeds. But on my 04 cbr1000rr when i break hard at high speeds or hard at any speed the whole bike starts to shake. Also when im just coasting with it off i can sometimes heard the break pad still touching the disks but ever so slightly. mostly worried about the shaking! is it time for new front break pads or what?
