overtime the pistons seized against the caliper body and the seals. You can get the pistons out and if they are not damage/pitted etc you can get away with cleaning them up and popping them back in. if not then refurbs are £100 a side

I had this problem with a mondeo yesterday. Only way to know for sure is to back-off & disconnect the handbrake and check all the parts invidually. Check to see if the actuator on the rear of the caliper isn't seized. Then check to see if the caliper slides are free moving, the piston in the caliper and the pads in the carrier.
If it's all free you're looking at a handbrake cable.

yeah as above. Sometimes just the handbrake mechanism on the caliper can sieze. I will have a pair of calipers by the end of the week. I will need to check them b4 i ok them

mine has done this a few times, first time is was a seized handbrake cable, and the last couple was the actual mechanism, i just squirted the lever the cable connects to with a little WD40, and has been fine since.

the wheels are binding to turn when its jacked up with the handbrake off, gonna investigate the handbrake mech! i think it could be that! i fookin hope so :/

i'm giving my silvia a little refurb whilst i'm at it, i'll get some pics,
i'm doing the sills as they are grotty on the outside but when i cut the outer sill away inside is mint :/ strange but i have new sills to weld on

front wings are frilly but i have steel to fix them so aslong as i can sort the brakes i'll be on my way to a new MOT
