When you apply the brake at slower speed does the lever pulsate against your fingers,
Didn't notice.take the bike out get speed up to 30.40 apply the brake,not to harsh,can you feel
it pumping your fingers,this is something you can feel if you have warped discs.

you should be able to feel warped discs when slowing down very gradually when almost coming to a stop you will feel the bikes brakes will be an on off feeling . best way to check discs is with a dial test indicator . i still think it could be fork bushes
