Rear calliper springs

guys I noticed yesterday neither of my rear calipers has a spring on the back of it,one of these calliper was put on new in dec when I got car as it had seized ?? Problem or not??
 
they dont have as standard a return spring for the caliper arm - thats not to say fitting one isnt a good idea
 
Yeah I wasn’t sure knew I read or seen something about springs,I’ll try and grab a couple from somewhere cheers
 
Yeah I've got a couple of Megan's ones to fit at weekend.looks like it will be easier with handbrake off I'm guessing
 
Yes that's the ones I got. I ordered two sets one for my toy 197 and one for my older lads 200 they only sent one set but quickly sent the other one out so think it was a genuine mistake.
