I'm having troubles with one of my Hope E4 calipers. During my last ride, the front caliper seized up and after pushing the pistons back on the trail I was able to limp home with out a front brake. I cleaned the pistons and lubed them with some silicone lube. Hope recommends some hunter lube which I can't get in Germany at the moment, so I used liqui moly silicone lube. However, the pistons still don't fully return. Any idea what's going on?
