Assembly in progress. But I run some hiccups. I installed XG 4 pistons caliper with 160 mm discs front and rear. Looks like they need to be on 140 adapter front and no adapter at rear. But still I can't say up then straight without rubbing. Usually my toopre tool was enough but not here. This is my first 4 pistons caliper so maybe I'm doing something wrong. Any ideas?
Hi,
The issue is with your front brake setup: your flatmount adapter is installed upside down!
These front fork adapters are asymmetrical because they act as reversible plates to switch between 140 mm and 160 mm rotors. Since you are running 160 mm discs, you need to rotate the adapter by 180 degrees. Usually, there is a marking like "160 UP" with an arrow on the plate—that arrow must point upwards.
In its current position, the caliper sits at the completely wrong angle and distance from the rotor. That is exactly why you can't get it aligned without rubbing, even with your alignment tool.
