These have been around for decades. Additionally, a lot of “braking” with these bigger trucks is “engine braking” like jake brakes, compression release, exhaust release, etc.

Can slow a lot by “simply” letting the jake engage.

We use them on our fire trucks, engines, tankers, etc, here in New England. Some of these apparatus way upwards of 30ton.

A two-wheel drive vehicle with an open differential is limited in acceleration by only one wheel (the drive wheel with the least traction). However, braking is always the combined effect of all wheels.
