Front brake caliper rebuild.

[DryRob]

I use a compressor with a blow gun with a section of rubber tube on the nozzle to form a seal but if that fails I use one of these:

I used a pair of these and they were great until I got to the seized pots. Don't be tempted to do what I did and use mole grips, they make a right mess of the caliper pots. Looking back I should have pushed the pots out as far as possible using clamps and wood before I took the caliper off the brake line (was replacing them at the time). I don't know if they're cheap/common but conventional pliers with gripping faces made of a softer metal might help if this happens to you.
