My parking brake is Non-operational on the rear left and the flex hose is split.
I remember this split hose was the initial reason I decided to work on the brakes last year, to replace all the flex hoses, but when I tackled the rear right the old flex hose sheared off in the caliper, so replaced that caliper, the flex hose, the hard lines up to the brake bias valve, and did the front flex hoses.
But I was too chicken to try and undo the rear left flex hose as I assumed it would shear off in the caliper and for some reason I couldn't seem to source a rear left caliper at that time.

Anyway fast-forward to today and I sourced a new rear left caliper (or so I thought)
After a few failed attempts with Autozone, where they sold me a caliper which was probably for a 20v, then the correct 20V caliper, but the rear left. The rear right is Out of stock.
I ordered one off Ebay, and its still not the correct one, it looks identical to my old one but 10mm too narrow.



I think I found the correct PN 853615424AX, but I cant find any reputable places that have it in stock.
Any suggestions?
