I was considering ARBs for my axles with an onboard compressor and tank set up and I came across a slight problem, the fact that air lines tend to freeze up here during the winter months. I thought about this after responding to an accident where a tractor trailer's air brakes failed due to the lines becoming frozen and wondered how susceptible are the lockers or lines to becoming frozen? Will a little bit of ice in the lines or the unit itself mess it up? Anyone have any input or have run ARBs in below zero temps?
