fuck the pics, i've fixed it
yay me

the reason it wasn't going back into the caliper is that the threads on the nearside caliper for the handbrake are theother way around, ie left hand so while i was pushing it in, it was trying to com eout, so thats whyit's fooked

handbrake still don't work mind but i have a cunning plan for that, i've already stripped the caliper down to it's component parts (too messy to get pics unfortunatly) but i've refitted it all back together so a trip round the block will show up how effective rear brakes are on a car
