Caliper Piston Stuck?

[VPplayer]

Hey guys,

Been having some brake problems with this VP.
When i am driving and come to a complete stop at the lights, if i let go of the brake pedal the car wont move at all.
It Idles at 1000rpm which i think is good, it has a very smooth idle and the engine was serviced last week by me.
But now its time to change the pads which i have no problem doing.
About 2 days ago i got a light pop up on the dash which i think its for the brakes, looks something like this (!).

Why are my brakes doing this and while i change pads and bleed the system, should i be doing something else so this does not happen again?

Thanks, Terry.

The rods that the two halves of the caliper slides on is probly dirty and sticky. Clean it good and grease it good when reassembling and you be good.
