When I first got my ZT-T it appears that had happened and on one side on the front, one pad was completely worn but the other side had jammed and was worn at an angle but only slightly...must have jammed soon after fitting by a garage.

Could there be an issue with disc run-out...maybe a tiny bit of something trapped between hub face and disc when fitting causing some slight wobble of the disc? Is there any wobble or vibration felt when braking?

Hope you find the answer is just clean and re-fit things?.

So I stripped the front caliper down, very rusty. Rust and carbon on the piston. Scrubbed as much off as I could, took the pads out, scrubbed the carrier and slides. Copper crest all over the slides and pad hooks and faces.

Got the piston out a little, cleaned as best I could (not much admitedly), pushed piston back in and re-assembled.

Took her for a run, perfect, vibration. gone. Wheel still a tiny bit hotter than the other side, braking evenly, but not like before. Stands for a day, took it out for a 5 mile run again (nearest shops as I'm quite rural), vibration back (not as bad, but back. Wheel hot again! Time to try and find a caliper as I'm sure it must be pinching on a touch and not retracting once it gets hot.....
