Steer Axle Brake Adjustment

?

Front brakes is something rarely adjusted. In fact if I remember my manual wrench days long before auto adjuster anything modern, front brakes are deliberately not allowed to "Lock" the two steers up front.

Without dealing with exactly what you have done or are trying to do to the particular truck, preferably with pictures... I cannot venture to help you further. I would just make a fool of myself.

 

If you're talking about parking brakes on a steer axle they don't exist (at least I have never seen it).

 

The chambers on the steer axle should only have 1 airline to each of them. That will be your air supply from the brake pedal valve.

 

As far as my guy that works my truck told me 25 years ago that only the rear the park brake on , infact just last month I had my steer replace on the truck was just the front and yes those bad boys was rolling free

 

Standard on FH Volvo's.
Option on Paccar's EU trucks(Daf).

 

Steer axles brakes only apply with air pressure, safety feature if you lose air pressure which would cause front to lock up and go into a uncontrollable slide.
So if you don't no this you should not be working on semi brakes, and probably don't have a certificate.
Serious business semi brake repairs or adjustments.
