Engine Brake in Traffic

[MemoriesByTheMile]

It would be similar to using only the rear service brakes, which could result in losing traction.

Interesting, for those with tag axles, does the tag axle have brakes? Or is it just supporting weight?
If it doesn’t have brakes than the engine braking is only engaging 4 of the 8 wheels of on the ground (50%).
Those with tandem axles and engine braking would have braking on 8 of 10 wheels on the ground (80%).
Hadn’t considered this scenario before.

Tags do have service brakes….but the engine brakes only work in the drive axel (so 4 wheels).
