ACF Dual clutches?

So i was playing some gmod trying to make a tank chasis without using wire welds. however when i wire brake to something it doesnt work when i click so steer can anyone tell me why?

Yeah ACF brakes are shit. Most people use two seperate drivelines on their tanks(this allows for pivot steering as well!), but you can also use Wire Clutches as brakes. I use this on my tracked vehicles and it works okay, bit herky jerky and everything handles like a T-34/76 or a bulldozer, but it works.
