New problem. I have broken parking brake return spring.
Apparently there is no spring part in Jag dealer's system
and junk yards wouldn't to sell spring alone.

I'm hoping one of you guys know place that would have
spring sold separately or have old driver side caliper in
corner of your garage in pale of "just in case" used parts.

 

Maybe have a few made

eg https://www.springshop.com.au/

 

I found 2 in States but it would take engineering
department to develop it, then program press to build it...
well, you don\t wanna know how much it will cost.

I found some springs at Aliexpress not exactly what I need
but with some effort and bending, under $5 why not to try
