Brake Check

Somebody tells me to "dynamite" anything, and I'm blowing the MFer up. Words have meaning, and I like blowing $#!+ up.

 

Technically speaking, dynamiting is an obsolete term from back in the days when trailers had no spring park brakes, just service brakes. You'd pull the trailer park knob and the rapid loss of supply line pressure to the trailer would cause the relay emergency valve on the trailer to send full resevoir pressure to the service brakes. They'd gradually release as the air leaked out.

 

Travel ????

I thought that's what the driving part was ??

........ I know .... I know ..... don't throw anything ...... Ok ?

 

Tip: THE SIX PACK!

If you didn’t know already, you can adjust automatic slack adjusters while sitting in the driver’s seat!

All you have to do is charge up the entire system. (Tractor and Trailers) Give 6 – 100% brake applications using the foot valve.

Count to 5 each time before you release you may need to build up the air system in between. This will keep all functioning auto-slacks in adjustment, including the steering axle.

It is a good idea to do 100% brake applications periodically throughout the day, when stopped at lights, waiting for a train or at the customer’s waiting for a door. *Keep in mind an auto slack will only adjust when the brake application is 90 psi or higher, even then only one notch at a time*.

 

My Doepker hoppers are like that, they have Hendrickson axles in them. I basically have to lay down and look up directly under them to be able to see the travel.

 

Not many guys know this apparently.
