"HD Brakes"

[Randall44]

In the sales brochure below, it almost implies that 16" wheels = HD brakes, but farther down the Options, it sounds like you could buy the 16" wheel upgrade without the brake upgrade.

My 2 questions

On my 2001 SR5, how can I tell for sure if I have the upgraded 13” front brakes?

And how do I identify if it has the 4.10:1 rear differential ratio?

I change my own fluids, but don't know what I'm looking at on brakes and differentials. Yet.

Thanks!

For the brakes, you could remove a tire and measure the rotor
