Hand Valve Brake

I have a large ball peen hammer that's heavy enough to hold it down and has a groove on the head where it kind of holds on to the handle and not fall off

 

A way too common method is to back under the trailer till you feel a bump. Get out and raise landing gear and hook up your lines. Jump back in and take off. Get going fast enough so your trailer completely separates from the tractor on the first turn you make. Also, raising landing gear seems to be optional .

 

If he's talking about the T-bar handle in a Cascadia, those grab and hold the brakes for a few seconds, something you don't want to do in the snow and ice.

 

No the trailer brake doesn’t grab and hold it for a few seconds, nor does a column lever. It will lock them dudes on fully and keep them there.

 

It's called a Trolly Brake.

Hit post too quick. This is used during times when you only want air to go to the trailer brakes. Otherwise you use the foot brake. I mostly used mine to tug test or to slide a tandem.

 

There are certain beam trailers and RGNs that don't have spring brakes. Without the hand brake, you're not going to get some of those heavy beasts off the ground. Even with ramps.

 

The new school way is most trailers today have spring brakes on them so the trailer won’t move if air is leaked off.
So you just back under and hit the pin.

 

Going to add one more reason not mentioned, if it's not your trailer, they work great for getting rid of tailgaters

 

Now your getting into the not recommended for novices use range lol

 

I can’t be that old because I still remember what we used a trolley brake for lol
