Just picked myself up a blobeye wagon last week and I've noticed what feels like the rear caliper sticking then releasing when pulling away.

The car seems to move freely with brakes and handbrake off however I've also noticed a slight squeal when driving along, possibly the pads binding ever so slightly?

Took the rear wheel off with the intention to remove pads etc however couldn't remove the pads pins! An I missing a trick or are these a pain to remove?

Hoping it's not anything more serious but trying to rule things out one by one...

Did you remove the pin retaining clip at the back. Once that's out you need to chap them out with a punch if they are stuck.

Give everything a clean and sand off any corrosion on the pins. Make sure the pads can move freely and also the Pistons can move back into the caliper.

The pins had a Phillips head on them so I assumed they where on a thread, is this not the case? If so I'll bang them out and check the piston movement.

The thread is to allow you to twist them when you fit the retaining clip. You twist the pin to lock the clip in place.

The most common issue is excessive brake dust stopping everything moving freely including the pads. Make sure you clean the sliders where the edge of the pad moves in the caliper.

The piston should push back into the caliper relatively easily but may need a g clamp or push back tool. If you open the bleed nipple before doing this you'll also prevent fluid being forced back the wrong way to abs unit and master cylinder. Just catch the fluid that comes out in a container and top up the reservoir when you're done.

Great advice, I'll have a go this weekend and see if I can free it up. Had the same problem on my old Clio but a clean up kept it going for a bit longer.
