1) Hook up car's hydraulic system, stomp on brake.

2) Drill and tap a suitable bolt to accept a grease zerk, pump caliper full of grease.  A typical grease gun will develop 1000 psi
or more.  There's a drawing in "More BS on TRs".

3) Fill interior of caliper with volatile solvent (eg Gumout), block off ports, heat until solvent boils and forces piston out.
Wear eye protection !!!
