I foolishly tried to remove the front brake caliper bleed nipple without applying any heat, when I first stripped the bike and it sheared off flush with the alloy caliper housing :-[ :-[ :-[ :-[ plus the piston was stuck solid and I couldn't get it out. I MIG welded a blob onto the top of the remains of the nipple and then gradually built up the weld to a bigger blob then clamped the blob in a vice and it came out no problem. I used this method on a broken off crankcase stud on my 750. I made up an crude adapter to apply up to 160 bar water pressure using a test rig at work but someone had nicked the power supply that runs it, so I just heated up the body of the caliper with a MAP gas burner and whacked the caliper onto a flat steel plate and the inertia of the piston freed/ moved it out. I then clamped a tool clamp on the insides of the piston bore and pulled the piston out. Like ever other Honda brake caliper piston I have ever removed from a bike left for yonks, the piston is badly pitted and need replacing along with the seal but the caliper body is fine.
