They have increased the size of the brakes because they have increased the towing capacity from 10k lbs in 2000 to 22k lbs in 2024.
My 02 chevy has factory 16" rims and disc brakes all the way around.In the us tire size changed from 16 to 17 and 18 oem when the rear brakes changed from drum brakes to disc brakes. There are absolutely no vehicles in the us that are rated 1/2 ton equivalents and higher with 16 inch oem wheels and rear disc brakes. Rear disc on 1/2 ton equivalent rated vehicles require at least 17 inch wheels to fit over rear calipers.
Actually the opposite is true thicker rotors hold temperature longer then thinner rotors . That's why high performance and some after marker rotors have groves cut in them. To reduce overall metal mass and increase air flow around and in the rotor to reduce heat build up since air dissipates heat far better then metal.It's all about 'thermal capacity'. Larger diameter, thicker discs cool better, giving better braking.
The brake pads on my truck with 20" rims are not 2" taller than the pads on the truck I had with 16" rims. It's all about the rotor. Measure them
Maybe if you used one of them there measurement doohickey thingamobobs you would understand that calipers extend above the rotors more than 2 inches. Much more in some applications.So you are claiming rotor size has not increased??
Brake calipers do not significantly stick up above the rotor, no matter the size of the caliper. Go take a wheel off and have a look.
The thickness of the rotor is offset by increased diameter with regards to cooling. This isn't rocket surgery, if you take the time and use your Googler I'm sure you will discover this.
Got it. So in your world the calipers have grown taller over the rotors and the rotors have not changed. What colour is the sky there?Maybe if you used one of them there measurement doohickey thingamobobs you would understand that calipers extend above the rotors more than 2 inches. Much more in some applications.
If you use the googley thingomobber you will find that rotor thickness has decreased not increased. You will also find the best rotors for dissipating heat are the thinner ones with groves machined into them to increase heat dissipation. You would also find out that the majority of braking occurs at the rear wheels not the front . So more stoping force must be applied to the rear than the front. Most brake systems also apply pressure to the rear axle prior to the front axle.
Don't need the googley thing to tell me what I did daily for over 30 plus years.
That was my thinking, I wear out more front pads than rear.60-80% of braking is front tires....
And fronts act sooner. Not uncommon to wear 2 sets of front pads for every set of rears.
NO WE WON"T!!!Wow you guys will argue about anything
YES WE WILL!!NO WE WON"T!!!
Hey you stay outta this.Sheesh, open a thread about grass market and you guys talk about trucks…… No wonder the world is the way it is…

the reason for a muffler shop on every corner was because the old exhaust systems didn't last. We have 3 pickups with at least 150,000 and 1 with well over 200,000 that have had nothng in exhaust changedThe reason there was a muffler shop on every corner was because they were simple systems that you could fix. Didn't have to have thousands of dollars of equipment to ensure your repair was up to epa emission regulations. You bought a stick of pipe bent it to fit picked a standard muffler of the shelf and welded everything together.
Same for mechanics they where mechanics not like today where they are computer diagnostic technicians and need a 100k machine to be able to diagnose the issue.
Why did we switch to aluminized exhaust pipe? Because with all the additional emission requirements the exhaust isn't hot enough to burn off the moisture that accumulated in the exhaust system.
As far as brakes being bigger today. I think you need to get your tape measure out. The stopping surface of the brake actually decreased by a significant amount when vehicles went from drum brakes to disc brakes. Wheel size increased because of the calipers on the rear wheels. Drum brakes didn't require calipers .
