Hi everyone, I've changed the caliper today and so far the wobble is gone. I'll drive a bit more tomorrow and report back. I'm keeping my fingers crossed it'll stay wobble free
Thanks to everyone who contributed to this thread
Glad you got it sorted. I had the exact same problem last Autumn. Turns out they were the original calipers. Swapped them out for Febi Bilstein items from Opie oils - problem sorted. Just bought a new set of calipers for the rear now as I can hear one of them staring to drag on the disc as well.
