It was called a bromse brake and the “idea” was that if you left the hand brake off and the vehicle lost its air pressure,when you started it up and had enough air the truck didnt roll away as you had the bromse brake pop out.
Suppose it could be called a hand hand brake!
Must be some bright buggers in Sweden.
Late reply sorry.
Yes I do have the trailer handbrake aswell. Handy in the winter 
But it’s the one in the middle I’m talking about; reading “Push to Supply” pull it and it will look the brakes on every axle. Yeah it can be a bit pain to use it sometimes and can easily come loose and your left with just the knob in you hand, the spring on the insde of the knob has to be correctly adjusted. I use it all the time in slipper hills to be sure the truck will stand still.
Volvo it’s a round knob but can’t remember what it’s say on it. over 3 years since I last drove one.
But if the temperature reads this love you should not use any brakes at all, stick with retader, veb or whatever the truck has, just not the brakes!

I still sit in a tshirt, it’s a scania. With a Volvo the heater would struggle to even keep the windows clear and you should be happy if the temperature in the cab is over +10c

35mph 
■■ my goodness a trip would take 2-3 weeks with that kind of speed but guess that’s the price you guys pay for buying crappy midlifts.
