We've owned and towed our Boler since 1994 using a GMC Saffari van and with a Dodge Dakota. The trailer does not have brakes and there is no provision on the axle
for them. We've never had a problem braking using these tow vehicles although if I had the option without doing a re-axle then I would add them on. If you don't put them on then always have your tow vehicle brakes checked before any major trip. And some things to remember.
-First, reduce your speed.This also helps your mileage.
-Try to leave a larger space cushion between you and the one in front and start slowing down well before your stop
-Finally use your lower gears to help reducing your speed when comming to a stop.
Again, if you have the option already on your trailer then by all means add them on.
