Braided Brake Line failure?

[Adam2201]

Hi guys, sorry if I'm hijacking the thread -feel free to tell me to foc off!  Just checked the brakes and I think I've found the source of the judder.  The retaining spring that sits on top of the pads on the left hand caliper seems to be warped  - you can rock it up and down by pushing on either end and it knocks against the caliper body.  I'm guessing it's knackered and needs replacing, but just to be sure I'm not doing something very stupid, does this look like it's seated properly?:

It's the same on the right hand side, and that spring doesn't move so I'm guessing it's positioned properly and it just got bent or warped at some point in the bike's life? The pin on the left has small grooves as well, probably because the pads have juddered around so much.
