Drum brake trailer vs disc brake trailer

Macker1999:
If the op is going to be using the one trailer all the time, discs the best way in my experience.

I have had problems with seized calipers with lack of use / zero wear due to VEB / Retarder.This now doesn’t happen as at service, wind auto adjustment off then pump brakes to readjust/check operation as per Knorr Bremse.

After 4 year’s / 44 t bulk use, original pads on my Kelberg with small discs fell apart [emoji849].

Sorry to disagree with other chap but by design drum brakes will fade way before discs due to greater cooling surface area and ventilation.

Also trailer manufacturers don’t mind what axle and brake choices are made , they just charge pro rata.
Schmitz may be different because they produce their own axle, but ( tippers )they will supply as per customer preference.

Bulker trailer manufacture is pretty small and bespoke and they won’t be buying huge volumes of axles. Last time I was at Gray&Adams in Fraserburgh they had nothing in their yard but drum axles.
