I've recently had some brake problems, despite lubrication, polishing the pistons, new pads and fluid they wouldn't hold very well. There was also a 'noise' when pushed back as though there was some binding.
New discs have sorted the problem. On one side the disc was half the new thickness. We think that at full travel the piston was jamming slightly hence not operating fully but also binding on release.
