That's the one Dave! First time I've done brakes hoses, after a while of wiggling and looking at it thinking wtf is this mysterious fixing. Went back out this morning when it was acceptable to make a bit of noise and gave it a little tap underneath, popped straight out.
Managed to get front complete today, looking very smart with new mtec discs and fancy green Hel lines fitted. Took a couple of goes figuring out best orientation of the brackets as you drop from 4 bolts to 2, but plenty of clerence full lock both ways now.
Just the rears to do and a full system re fill and blead and it should brake better than ever before.
