Looking at the weights on the Real World chart there are many a 13''s in the 2000/2200lb range and one all the way up to 2560lbs!!! Can not imagine what all was stuffed in the later trailer!
Trillium Rv Carol, not an Outback
. Weighs about 1700 lbs.
My previous trailer had 10" drums and was easy to lock up. To adjust I would lock the brakes
and then back off slightly. When the OEM bias ply tires needed replacing I bought radials. When the time came to adjust the brakes
it took a considerably higher voltage to lock the brakes
. The only difference was the tires. Better tread, different profile, different rubber compound may all contribute to an increase in fiction? If the magnet can't overcome the rotation then there is no lock up. Most folks with a #9 axle
will say you can't lock the brakes because the pads are too small but I think tires come into the equation as well.
