Braided Brake Line failure?

[Deefer666]

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..

Check that your pads went into the caliper "square" & aren't snagged up on the anti rattle plate, check the pin for grooves where the loop of the pad sits, when reassembling put a smear of copperslip ON THE BACK OF THE PAD. And smear the pin with copperslip when you put it back through.
