To free up and remove stuck cylinder:

1. Squirt PB-blaster down gap between piston and brake-caliper

2. Use C-clamp and tighten on working piston to hold it in position.

3. Squeeze brake-lever to force out stuck piston

4. If piston doesn’t move, use another C-clamp on stuck piston to push it inwards.

5. Remove C-clamp on stuck piston and go back to #3.

6. Repeat steps 3-4-5 until piston is freed. Also some gentle heat from torch may help, but don’t over do it.
