Theres that topic again....brakes, which I know nothing about.
How do I fix it if it is that?
Remove pads,
Undo the caliper bleed nipple a quarter turn to eradicate hyrraulic pressure from behind piston.
Apply piston compressor or Medium size G clamp & see if piston moves freely back in to caliper.
If brake pads are low & piston is extended, some dirt or grit my have got past the dust seal or indeed the dust seal is damaged so check it.
If the piston is not moving in easily, then I would suggest removing the dust seal & examining the piston for corrosion damage.
Sometimes you can clean them by using hydraulic pressure from the brake pedal to push it out to fully extended position.
Dont over extend it or it will fall out so put a piece of wood in front of piston when you do this so it pushes out about 15mm.
You can clean up the piston or replace the dust seal but once damage to piston has occured you find it sticking again.
Service kits are available or you get another caliper.
Thats the way I would do it, but some would not undo the brake bleed nipple as it dores mean bleeding the brakes, but this way does mean no undue back pressure through the ABS or Master cylinder.
