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?
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.
I'm replacing the pads as they'd worn unevenly, I think I've sorted that issue out though now. If I'm getting no issues with braking apart from a slight noise it's rotating, I assume it's OK to leave as is?
