Braided Brake Line failure?

[Adam2201]

Cheers both.  Will take the pads out tonight and have a good look at the disc surface / pads/ retaining pins and clean everything up.  Otherwise will try lines then discs. Because the juddering started right after changing the pads it's leading me to think it's related, but then the braking power with the new pads is so much stronger so it could be showing up a problem that was already existing somewhere else..
