No, caliper was ok, its the guide pin that's seized. Can't shift it, tried everything. Think I'm going to just replace all the braking system.

Put it all back together & my brake pedal goes straight to the floor, brakes hardly working. Feels like air in system, not sure what's going on, never had to bleed brakes cus of pad change before? Have I missed something?

Car still at my dad's. Had to get the better half to save me lol
 
mole grips should shift the pin with enough penetrating fluid,does fluid in res splash up when pedals pumped looking in through cap
 
It'll take a pump or two before the pads sat in the right position but otherwise no you shouldn't need to bleed.

Did you have an issue before changing the pads?

Tried mole grips. It's solid. Going to keep soaking it for a few days to see if it can shift, but I don't think it'll go. Oil doesn't splash, it doesn't move up or down, beginning to think cylinder might have popped a seal.

No issue before, other than squeaky pad result of seized guide pin. Pumped pedal loads, it's goes hard after 3 or 4 pumps. But then 10 secs later you can push it straight down to the floor.

Think I might have to get the nanocom plugged in to see what that's saying.

diagnostics wont help with your issue of pedal,if res doesnt splash you may well just need to bleed system

I'm hoping that's the case, which is weird, change hundreds of brake pads, never had to bleed the system after.

Looks like my nanocom has got some bleed functions on it

it probably has but old fashioned bleeding is all it needs, a poor piston seal can allow air in when piston is pushed back
