do not buy pattern brake seals...the fekkers swell with contact to dot 4 brake fluid and the pistons are then wedged so tight you need 4 weetabix and  a crow bar to get em out ...get yamaha oe  any thing else at your peril

		I also had issues with a Nikone front caliper seal recently.  Partly due to operator error, I suspect, but they're not the easiest to fit.

		I rebuilt the callipers last year and the genuine seals were 100 quid odd. Nearly shat mesen at the price. Makes me feel better having spent all that, sorry to say.
