He put carbon ceramic brakes on it? How much you want to bet he doesn't know shiat about those kinds of brakes, didn't warm them up, and then ate shiat into the tire wall?
Carbon ceramic brakes must be brought to operating temperature or they won't farking work.

I don't know what carbon ceramic brakes are, but this sounds like a horribly stupid requirement for a safety device.

Ok, so I spent 10 minutes reading about carbon ceramic brakes.  So, basically these things don't decrease stopping distance, don't work well in the cold, and cost a shiat ton of extra money just for the benefit of not having to replace them as often?

These are the Door Dash of automobile accessories.

NO NO NO! Are you new here? Don't go confusing yourself (and us) with facts and information. Your initial opinion is invariably correct. Just let it rip and fight to the death against any naysayers.

You seem to have missed the main reason for them; due to their amazing ability to dissipate heat they really reduce brake fade, which is the factor of reduced capability that "normal" brake materials suffer as they heat up under repeated heavy use. Steel discs are heat sinks and hold the heat that builds up for quite a while; these are designed to shed that heat as quickly as possible.

I did read that, but I'm not entirely clear on the meaning here.  I thought that brake fade meant that the brakes were literally losing matter as they worked.  The source of all that dust.

As they heat up under continuous heavy usage (such as track use), traditional braking systems lose capability - they literally fade. This can get really dangerous as they basically stop working.

There are various ways to combat this that include composite pads that deal with the heat better, steel braided brake cables instead of the rubber ones that are standard on a lot of normal cars, bigger discs (to dissipate the heat better with more surface area), punching holes or slots into/through the discs, or ceramic composite discs themselves. Most people use a combination of the above - and a lot of performance cars come with a mixture of the above as standard.

Traditional brakes rely on friction to stop the vehicle. The energy of the moving car is converted into heat, but as the components heat up the coefficient of friction gets smaller, and you need to apply more pressure to get the same amount of stopping force - this is called brake fade.
He chose the carbon ceramic brakes because they are lighter and can handle more heat before the coefficient of friction drops (they have less brake fade). His mistake was that rotors, pads, and calipers, and brake lines are only part of a brake system. The part he neglected was the fluid.
Brake systems are hydraulic, so they rely on an incompressible fluid. Besides lubrication, being non corrosive, and stable, the fluid must not boil. Once it changes from a liquid to a gas, it's no longer incompressible - and when you apply pressure, it's used to compress the gas bubbles, not the brake calipers. This causes total brake failure.
Since he replaced everything else, including the lines, he also had to replace the fluid. Rather than choose a high temp brake fluid meant for the hotter running carbon ceramic brakes, he bought basic Dot 3 fluid (that works perfectly in stock systems). This was a big miss on his part, and although I'm no fan of Tesla, they should counter sue the moron for making their company look bad with his own ignorance.

No, all you're doing is running a motor in reverse.  The pads don't touch the rotors.  It's why brake pads in EVs and hybrids last so long- the majority of braking is regenerative rather than friction.  (At least, if you're doing it right.  Slamming on the brakes all the time wastes range)

For non-emergency braking, the regenerative system engages the motors so that the wheels are putting energy back into the battery, a similar but more subtle sensation to downshifting in a typical ICE car. That does most of the work when you're driving and braking normally.  If you slam on the brakes, I believe the system bypasses the regenerative braking and goes straight to the disc brakes.  So if you're driving normally, the actual brake pads get very little use.

Chet is a YouTuber that's been on a mission to make his Tesla Model S Plaid as lightweight as possible for a while now.

I get the point of trying to reduce unnecessary weight, especially in EVs, but this arms race is making cars seem flimsier by the day. One of my colleagues has a Tesla, and at highway speed the road noise is unbelievable. I'd trade a few miles of range for some decent noise dampening.

You're not running "a motor" at all.  In regen mode the motor becomes a generator.  It stops the car by turning the mechanical energy of the car's momentum into electricity to charge the battery.

No, they stop working as well as they heat up, but go back to working like normal as they cool down. It's not the same as the material wearing away.

Okay, this is kinda funny.  If you go to Unplugged Performance's website, the page for the Model 3 says A professional brake bleed with high performance fluid is a requirement for the functionality of our brake system.

The page for the Model S says nothing about upgrading to a higher temp fluid.

Well, if they're doing it the smart way, regenerative braking should just cause the drive train to use the motor to slow down. Turning a motor by hand just makes it a generator, basically. But it takes a lot of work to turn a gennie, so it's able to bleed off power.

So, he wanted to lower the weight by 30lbs? Google tells me a Tesla Model S weighs 4560 at a minimum. Now, I ain't no math wizard, but that's a reduction of less than 1%. Is that meaningful in any way?
