OK, this is getting a little crazy. This morning it was -15C and my brakes were frozen. I have dual mechanical disc brakes on my recumbent trike. Due to the unfortunate mounting position of the right brake, it's easy for water to enter the cable housing and freeze up. The left is a bit better in this regard because it's mounted "upside down." I try to keep the entry points covered up with marine grease, but it seems to wear off so fast and it's hard to keep up when I'm commuting every day.
I have two questions:
If I switch to hydraulic brakes, will they continue to work down to -20? -25?
If I keep the mechanicals on, is there a better housing I can use to completely and reliably seal out water?
I'm tired of gorping heavy grease on my bike. I'm tired of not being able to stop! Any suggestions?
