Yeah. Bilstein doesn’t bother with cars like that. I have them on BMW. They don’t even make B4 for it. But on new one it seems Toyota is using Bilstein on XSE version. But there are complaints about ride, which means they slapped harder shocks and left everything else the same.
Oh man, you have to admit the vehicle would've looked awesome. Lol.
Nah just rotors. You cannot slap Brembo calipers on that knuckle. I toyed with idea to slap calipers from Tundra etc. But then larger press area, probably resulting in soft pedal, then I would need master cylinder from some other car etc. It ain’t BMW that comes with coding option for Brembo and off we go.
The run-of-the-mill Tahoe and other large GM SUVs have puny looking brakes.
Even the undersized brakes have good stopping power until they overheat.
That is what many manufacturers design. Brakes sufficient for 2-3 hard stops. Problem is also choice of wheels. Many appliance vehicles come with smaller wheels to keep cost of ownership down.
Great point, just as like with a cd number for a car, never do you see the frontal area in the marketing materials. My Lexus has a .27 cd and if it had the air suspension, .26. That's super low. But the frontal area is not small. That happened to be 1/4 criteria the engineers were given in the 80's, when Lexus was created. Top speed was another which is amazing. They're now limited to 130 mph on most models, but the original was capable into the 140's....
It's funny how everyone here knows a C63 or S63 is a real AMG. But there are many who see C43 or M240i (I'm making it up I don't follow anymore) and think these are AMG or M because of trick badging. I remember seeing a t shirt: C43, Do you AMG bro?A simple first step is to determine kinetic energy of various vehicles:
KE = 1/2mv2
Kinetic Energy Calculator
If you know the mass and velocity of an object, use the kinetic energy calculator to find it's energy in movement.www.omnicalculator.com
Take a 2020 Ford F150 with a loaded travel trailer at a combined 16,000lbs (nearly maximum GCWR) traveling 83mph (maximum speed for most trailer tires).
That combo has about 4 million joules of kinetic energy that the brakes would need to dissipate.
Now look at a 2020 Mercedes Benz C63 AMG. Only weighs 4,400lbs, but has a maximum velocity of 175mph.
The C63 generates a maximum of slightly over 6 million joules of KE for the brakes to deal with.
This is obviously super simple and there are many more variables, but it does outline the relationship between mass and velocity when it comes to energy.
FWIW, our demo F150 has 350mm rotors and the C63 AMG has 360mm rotors.
imho this lends to the phenomenon where my RWD BMW has rear pads that wear at 2X the rate of the fronts. Normally, just common sense and physics, front brakes do more work than the rears. Even upon reset, the computer shows the life of the front pads as double the rears. The car is a manual and it's so annoying to have the brakes grabbed in the rear for how ever many ms it is, as a hill holding feature. Maybe moot but I wonder if a 2022 manual car has that, it's terrible.
Many manufacturers are using floating in the back. I saw that Lamborghini Urus or whatever the name, with floating in the back. Many Tesla’s have that too. KIA has that on Stinger bcs. when you are new kid on the block, you better have all stuff sorted out. Still didn’t help them.
That is bcs. all electronic nannies. It is big problem since 2004 when all these DSC features were introduced. Get ProTool and go to DSC coding and you will see list of like 30 different functions. But really big one is vectoring or electronic differential function. It absolutely obliterates pads on track and affects life of pads on street especially if vehicle is pushed.
I was going to ask what happened to the van. Is that why you have the Pilot now?
When I was a kid, I learned the hard way on a pad replacement job....it's tempting to try to push the pistons in, on fixed calipers, without removing them. It's very possible, even with a screwdriver. But when I bent them on a friend's Porsche and had to pay for the caliper, started to make sense to remove it and push them in the right way....on a Lexus, Toyota wants the caliper bolts replaced, and they are pricey.
As long as your ABS can activate, you have adequately sized rotors. Larger rotors are for heat sinnk/disapation as you are seeing on performance vehicles for repeated brake application/reduce fade. Your tires are what is controlling stopping distance (assuming brakes can lock up/ABS activate). I have a massive aftermarket "BBK" (big brake kit) on my Sportwagen and have some great data for you on this (focus on the stopping distance 60-0, not the time). Comparing 312mm singe-piston sliding caliper stock brakes to the 350 6-piston BBKs, same tires (close enough)...stopping distance? The same.. Change tires to summers? Shortened. Road and temps were for all intents and purposes "close enough" (the Dragy temp isn't always accurate) for this test so variables controlled to the extent I could. If I would have done repeats the BBK would have kept the distance same/similar each time while the stockers would have faded into the distance.....
But then when you go to order brakes for a VW Golf there are like 2-3 different size diameters. They size "appropriately."
Nah. My in laws left it with us. Most uncomfortable vehicle I had it in two decades.
I don’t think it is just car nerds. My wife never knew brakes like on Tiguan exist until she drove Tiguan. All her previous experience was Asian vehicles. Now, she would never go back to Nissan or Toyota and brakes, handling are primary reason. I guess what you saying explain people’s unwillingness to buy anything outside their comfort zone, so they don’t know for anything better.
fixed calipers in the rear are not cost effective or worth the manufacturer’s time. when drum parking brakes left the german brands threw in the towel. fixed rear needs a separate floater epb or super expensive integrated fixed caliper.
Honda was notorious in the late 90s early 2000s for having warped rotors. Every early honda that I owned did this. I did quit using the cheap tire shop and went to discount tire which helped as they use a torque wrench not an impact gun.
