Arbitrary numbers?

One big fib was 1/2 tons have nearly the same brakes as a 3/4 ton. Brakes are a axle rating function at a minimum... example;
A F250 Ford with a 6k fawr and a 6340 rawr = 12340 lbs of braking performance

A F150HD Ford has the heaviest specs with a 3750 fawr and 4800 rawr = 8550 lbs of braking performance.

Lots this guy simply doesn't know but he has a opinion like we all do.

I'd like to discuss this point further because I'm a 1/2 ton guy that tows heavy.

I've always been intrigued by this very point.

I drive a Tundra and it has, when it was originally designed in '07, huge disc brakes front and rear with a very capable front and rear axle.

So the question is how are the brakes on the new class of half tons - if equal in size - not as capable as an HD equivalent?

Thanks!

It's not just rotor size that determines brake capability.

It's the overall mass of the rotor for better heat load - heavier can absorb more heat - these are friction brakes after all. It's also determined by the calipers. Number of pistons, the hydraulic pressure used to actuate them, etc. There's also different materials used for the friction pads, with different coefficient's of friction in the material.
