Failed laden brake test
Hey guys,
What is the correct procedure after failed laden brake test of the tractor unit? Clearly during the test truck has to connected to the loaded trailer so that's kind of tricky what to do with this load(trailer), after the failed result of the test.
I guess its big NO for driver to continue and deliver the load or come back to base with it or just get to the workshop as soon as possible, even if its only few miles away?
Thanks!

thanks, testing centre said that this particular fail is not serious and truck can come back to base with the load which made me think what in case of accident on the way back/?

The RBT sheet shows issue with foot brake pressure on the 2nd axle service brake. (Could be related to the weight, or load sensor setup).
Deglaze & pads will help, but I would be testing the brake pressures, & load sensor (if it has one). Or get more weight on the axle? Move the fifth wheel forward?

Pressure related issue to 2nd service brakes, Possibly load sensor issue. Try moving the fifth wheel to move more load onto the 2nd axle, depending on design weights.
What is the axle design weights for each axle?
