Thanks for the help fellas I cleaned them up with my dad today everything moving nice and freely. All the seals are fine and it looks like I need some new pads as they've been wearing unevenly so I've ordered some. The wheels spins freely with a little rubbing and I can still hear the noise at speed so I'm assuming what I can hear is normal and I'll see if the new pads change anything.

Jusr looked to see how you was getting on. Surpurised you can here them at speed. If the calipers free off after brake applying and allow the wheel to spin there can't be too much wrong.

It might just be me being overly cautious, I can only hear it with my visor open and when I come off the throttle.

Put on stand. Face head on to the wheel spin it fast and watch very closely at that brake disc it could have a in tolerance bend that catches the pad hence you can hear it the faster u go

It could well be this, had a look just now and it's hard to see but there's a point that sounds like it's catching on each revolution. Is getting the braking faces skimmed an option here to get them flat, or is it just a replace job?

Well my way to bend back involves tools but the old timers here will just disagree and give 101 reasons why you shouldnt

If the brake does not judder when applied and the brake feel is constant, leave well alone.

Braking is fine, I'll leave it as is and just keep my eye on it.

Skimming discs is not an option.
Skim a disc with too fine a finish and you can land up arse over tit (front wheel lock up).
Some brake discs eventually get hard spots (often incorrectly identified as warped disc) in them, no amount of skimming will change the material properties of the disc.

The correct thing to do is to replace both disc and brake pad, if the disc is worn beyond specification, with grooves etc and the brake pad has taken its shape.
