Hey guys,

I would like to ask for your help with adjusting disc brakes.

Bike: 2019 Kona Mahuna
Caliper: BR-M395
Lever: BL-M396
Problem: Rear disc rubs on pad only on the NDS.
Have done: I watched multiple videos on how to adjust disc brakes.
- Moved pistons (without pads) in with a tire lever and out by pulling the brake lever to lubricate them properly and to make sure they move evenly in the caliper. They seemed to move evenly..
- Bled system using Shimano's funnel (front of bike was raised).
- Tried to center caliper the usual way (loosen bolt, press lever, tighten bolt) many times with no success.

Could be the issue:
- too much oil in the system
- bent rotor (slight bend)

Do you guys have any idea where I could be making a mistake?
