Went to take the calliper of my rear disc to upgrade handbrake. However as you can see in the clip attached there is a lip on the disc. I've never seen this before, all four have them. I've only seen discs fully smooth. Is it common? You can see that's stopping the calliper sliding...
I have a BJ70 with disc fronts and drum rears on leaf suspension and am wondering if axles from a more recent HZJ75 Troopy with leaf springs and disc brakes all round will bolt straight up? Interested in the disc brakes and rear ff axle. Are the front discs larger too?
