Just got round to replacing my pads on my R8020 hydro disks. One piston was stuck out way further than the other. I pulled the brake to show the pads and then cleaned them with alcohol. When I pushed them back in, there was a hiss from the hood. Did it again to clean some more and the same hiss.
Now the lever pulls right to the bar and barely engages the brake. I can't see any oil etc under the hood. Do I just need to bleed them, or top up the system? Running for about 9 months working fine until now.
