Re: "Dunk it in boiling water and then try."

This works perfectly. Place piston in caliper with the dust boot groove about a centimetre proud of caliper lip. Put the dust boot seal in plastic bag to keep dry, leave in boiling water 5 mins then place around the back (blind) side of caliper rim first pushing down, finally push down over front while still hot. Slip seal into groove in piston all the way round, and push piston fully in to allow fitting of the new pads. After it cooled there is no sign of the seal coming adrift from the lip. So the heat expanded the metal reinforcement ring just enough to allow fitting and now a good seal.

Thank you!
