I have been rigerous on my routine however do no more than change the fluid each 2 years. I had a caliper fail at only 110k.

I remove one caliper at a time and then press the brake pedal two full times - check the piston and then two more presses if needed. The piston doesn't need to come out far, but just enough to move it. The rubber bellows will be slightly stretched and easier to check for any snags. I then press the piston fully back in and make sure it is free - releasing the bleed nipple to expel the fluid. Re-assemble the pads and caliper and move onto the next one. The mot chappie usually comments on how perfectly balanced the brakes are.
