I saw once when something except for a UD, when DAFs were perm
on 189, there was once when the BC experiment with the handbrake
when he was driving, obviously there was someone trying to 'psycho'
him into trying, but when the lever was pulled back, nothing
happened, all the way until the bus was about to stop completely by
conventional brakes then the loud 'chiiiiiii' sound came up and the
handbrake is really in power.
But regarding handbrakes, they use alot of gas, or that air from
the compressors right?...
