I've got Rever Havit on my Hurricane. The rear is super: crisp, effective, reassuring. The front, OTOH, is soft and flabby and I have to haul on the front lever so hard it often gets stuck against the bars. I've tried the tension screw (it achieved precisely nothing), and when I adjust the cable length the tolerance between squishy and rubbing is nanometres. Clearly the brakes are not just rubbish brakes, because the rear is fine.
Is there a trick to setting up mechanical discs? Please don't tell me to fit hydraulics instead, it's not helpful.
The Hurricane has internal cable routing, if that makes a difference. I can't make the barrel adjust turn, even using pliers -- the only way to adjust tension is to undo the cable at the piston and adjust it there.
