was fine for the first 100km or so, but now after about 200km it's pretty bad, I don't think it's the fork as I'm getting this both front and back on medium to heavy breaking at any speed

I'm wondering if it is the rotors looking at the profile of them they don't make full pad contact the whole way around

has anyone else experienced this?

I did, and replied back on the Tripster thread. Did you try what I suggested?

I got the idea/answer from here: http://smutpedaller.blogspot.co.uk/2014/01/trp-spyre-disc-brake-review-first.html

Slightly warped disc.? Look carefully to see if the disc is rotating perfectly straight between the brake pads with no wobble... Or try copper grease on the back of the pads

I've trued the rotors as best I can, I had them running really sweet with no rub and only a tiny bit of lever movement required to bite on, the judder is more rough feeling than I'd expect from a warped rotor, like it's the profile of the rotor grinding into the pads, but who knows

the copper grease is interesting, I'll try it

Yes! Exactly this, posted about it a few times, has been doing my head in. I must have subconsciously taken notice of Jamie's advice cause I finally got hold of some copper grease yesterday and applied to the back of some new pads. Unfortunately the pads hadn't really bedded in on the short ride I did yesterday so not sure what effect it's had yet.

Had very bad judder when I fitted mine. Found out on my shake down ride.

A dab of copper slip on each backing plate completely removed it for me. No problems since ๐Ÿ˜€

Whoops. Looks like it was Birdage I replied to on the Tripster thread. Apologies, OP.

Anyway, advice is still the same. Put a little smear of copper grease on the back of the pad, being careful not to get any elsewhere, and it should be an instant fix. I pissed about with changing rotors etc, and this is what sorted it.
