^^^ Could be a regional thing. In the 1990s some time, I had probably seen 10 Saab products and a half dozen Subarus. Then my parents dragged me to Connecticut for Christmas to visit my brother who was working there at the time and it seemed like every third-fourth car was a Saab or Subaru.

 Either this bit was garbage, or the cordless at my work has more power than I thought. I had drilled a pilot hole and switched to the phillips to install a screw. Popped it in there just fine, then I wondered why my phillips bit was so flat.

The newest H2s are 13 years old now. They're also effectively an overweight GMT800 Tahoe/Yukon, so they burn through consumables more often (and some things that aren't really supposed to be consumables). And each year the Tahoe/Yukon alone outsold the H2 by about 10:1. I also get the feeling that once popular culture soured on the H2 and it went from "symbol of success" to "poster child of American excess and the 2008 financial crisis", there were very few people left who want to shovel money into keeping an H2 going.

yeah i'd guess the used market for H2's died up before they even stopped building new ones. they were basically mercedes with how often they needed maintenance due to the weight of the fucker without any of the prestige. they also weren't actually good at offroading so they didn't get turned into crawlers or anything once no one cared about them

On the subject of Audi UFO brakes, has any (overcomplicating German) manufacturer ever tried anything with stacked brake discs? Like inner and outer brake discs, each with its own caliper. Or with one caliper with four pads in it somehow?

There are multi-pad per side calipers out there, I haven't seen stacked discs though. That'd be a thing, haha.

Old volvos rovers run dual lines per caliper for redundant braking. Rolls/bentleys run dual calipers for disc for redundant braking.

Aren't the brakes on most (all?) airliners multi-disc affairs, like super-sized versions of automatic transmission clutch packs? The downside of multi-disc braking on a roadgoing vehicle is you'd be doubling the rotating and unsprung mass of your brakes, and I don't even know how you'd package a brake system that wide unless you did something nuts on a four/front-wheel driven vehicle where you have one rotor/caliper mounted inboard at the gearbox, and one rotor/caliper mounted outboard in the conventional location.

Large Testicles posted:it would actually help prevent the wheels from locking while being able to slow faster, hence airliners doing it like IOC pointed out That's not how it works. If the brakes are strong enough to lock the wheels/skid the tire, then they're more powerful than needed for maximum effective brake output for a single stop. If you need more fade resistance or to be able to handle massive loads (Aborted takeoff or reverser failure, plus not catch fire), then you need more rotor area and more pad area. Track/Autobahn duty is another reason for bigger brakes, but that's not really what manufacturers are shooting for. The cheapest brake system is. sharkytm fucked around with this message at 23:41 on Aug 8, 2022 |

Changing pads on UFO brakes https://www.youtube.com/watch?v=4g2s_xX3nmw Audi gives you a plastic pin to align the wheel and rotor since there aren't studs to mount the tire on. If you know about it in advance and it's daylight, it's fiddly but not difficult once you get one lug in. Goober Peas fucked around with this message at 23:56 on Aug 8, 2022 |

Track/Autobahn duty is another reason for bigger brakes, but that's not really what manufacturers are shooting for. The cheapest brake system is. Aircraft brakes only have to handle one hard stop at a time, though. There is a prescribed cooldown time after a rejected takeoff, even on smaller planes like the Cessnas I used to fly. Cars have need to keep driving after an emergency stop, potentially doing another one a few seconds later. Arguably car brakes have a bigger task since they need to handle long down hills, etc., aircraft brakes can be engineered to not overheat on a single rejected takeoff, but then must wait to cool down before another takeoff attempt.

The fronts already do the majority of the braking. So if you added inboard front brakes to a RWD vehicle, you're adding an obscene level of complexity to solve a mostly-nonexistent problem. The UFO brake is a "solution" to a problem that partly existed because Audi insisted it should exist, by sticking with 15" diameter wheel. Also, I was never suggesting aircraft brakes were a good idea for cars, just an example of a multi-disc solution to braking in general. As has been said, even with modern super sticky tires and downforce and heavy cars and assloads of horsepower, a single (giant) caliper squeezing two pads on a single (giant) rotor is still the best solution. More than capable of generating enough braking force to lock the tires up on at least one stop. Combine that with modern pad compounds / rotor materials and at least some effort at getting air over the brakes and now most cars have brakes that would make sports cars from a few decades ago jealous.

True. I meant catastrophic fire. F1 brakes occasionally catch fire during pit stops. It's not great for them, but so long as they get moving and blow the fire out, it's part of racing.
