Evening all. Iv got a rr6 and when I brake I have a pulse in the lever and judder on front end, I my thoughts straight away is that it's the discs but before I spend money on new set is there anything else that it could be? All the help would be great. Cheers
He's referring to the metal rings in each disc as the bike has floating discs where they move sideways slightly to stay central to the callipers as the pads wear. The metal rings should spin freely, but can be cleaned up if they're seized.
Do check Colin's suggestions too though, it may be quicker to lift the front and see if the wheel or steering have any play which could also cause your issue.
