It's really windy today, and the rain tarpaulin makes a good sail for the bike I'm storing on my balcony. Short of actually mooring the bike to something, I decided to just fasten the tarp a bit tauter and tying down the brakes to stop the bike rolling back and forth. With mechanical brakes I would have no concerns about this, but now I'm wondering: are hydraulic brakes also ok with it? After all, they're not static but kind of “self-adjusting”, and the pistons move out over time as the pads wear down. Does this cause any problems if the pressure is kept up for not just minutes as it might in a normal descent, but days on end?
