[size=1em]When I did mine I used an air-line.[/size]
[size=1em]I held three pistons in place and fired the fourth one out with compressed air (air line attached to the brake hose).[/size]
Replaced the seals put the piston back in and then did the next one.
[size=1em]I don't how hard it is to do if the pistons are seized though.[/size]
[size=1em]I suppose it must be possible to undo the 'blue spot' torx type bolt, but I've never tried it. [/size]
