Disconnecting steering axle breaks?

no, you cannot disconnect them. at one time, there was a valve on the dashboard. (i forget the name, but i think, "brake limiting valve"..??)you would switch that valve from "dry to wet" if the roads were say, well...wet.

it was thought way back when, that you could lose control as if the truck were to start skidding as the wheels that start to lock up, tend to "take the lead".

well if you are going forward, those tires are already in the lead.

it has been, many, many years now since any truck has had that valve on the dashboard. the computer anti-lock brake system helps prevent wheel lock up and skidding.

so NEVER try to shut off the air supply to the front/steer brakes.

 

Back in the day it was also common to totally remove the brake assemblies and drums from the steering axle and never get questioned for it at a scale.

 

Why remove it? It's on the actual permit test...

 

Sounds like the tests are about 25 years behind the times!

 

doubles / trips...... I thought it was some kind of trick question......got it right anyway

BTW....thank you very much for the tests. It's appreciated.

 

You might have questions on some other outdated things as well.
Like "wig-wags," Test takers also confuse the modulating control valve with the brake limiter control, obscure stuff, but it's on the tests.
