"You don’t NEED brakes. You ride a bike to go, not stop. If you really need to stop, you can honestly just put your feet down in an emergency, or in most survival scenario cases you really may not need to be stopping at every damn stop light. Never plan to put hydraulic disk brakes on a survival rig. Too technical. Rim brakes are fine, but they do over long periods of time, actually remove the sidewall of the rim, eventually destroying you wheel even if nothing else is wrong with them, but it does take a while. If you’re breaking in sandy conditions, less time is needed. Common sense stuff."
