Braking power

[Cyber1qhorsey]

I had to do a hard stop.... Full blown panic mode on my part!! ??

Is there no enhanced braking autopilot assistance yet ? The CT should have stopped itself???

Hey guys, this is what happens when 2.9s acceleration is the marketing focus. You boys act like you’re driving super cars when you’re driving a shiny beautiful brick. Drive it like a 7k truck and you’ll do better.

You’re welcome

Don't be ridiculous, Tesla has always taken emergency braking and safety seriously, even when they target acceleration faster than 2.9 seconds.

It looks like people are trying to construct another false narrative because the Cybertruck's stopping distance is not limited by the brakes, it's limited by the amount of friction the All-Terrain tires can generate. That's why it has anti-lock braking.

If a Cybertruck is not bringing the tires to the limits of adhesion when braking hard, it needs to be taken in to get fixed. Don't treat what might be a defect as if it's normal with all Cybertrucks.

It's also possible that the driver has their seat adjusted in such a way that it makes it difficult to apply braking pressure. A vehicle with off-road pretensions needs to have brakes that are proportional to pressure, touchy brakes are a no-no on loose surfaces where the truck may be bouncing around. For that reason, they are often designed to need a firmer pressure to reach the point at which anti-lock braking kicks in. I can see how someone not used to driving trucks could think they are pressing hard, when they are not.

Has anyone done a hard stop 80 mph to zero braking comparison between the cybertruck and the cyberbeast? Maybe it will turn out that the extra braking from the third engine is actually even more desirable than the acceleration boost for all practical purposes.

Then again, maybe not. Would be interesting to see.

Compared to my early single rear motor Model S my wife’s dual motor Model 3 has so much more regen going downhill on mountain roads. It’s like downshifting a manual without the hassle of a clutch to manage and I love the control. Thus my postulated improvement in braking and downhill driving with a third motor… BUT the model S and the model 3 have a big weight difference as well. So maybe even 3 motors won’t be enough for the weight of the CT/CB to make a significant enough impact. I’ll be interested to see how that comparison shakes out.

Guys I had my Truck for less than 350 miles. something happened i cant explain... I was driving like usual and when coming into a turn releasing the accelerator but the speed wasnt reducing... so i pressed the brake... but it didnt engage.... until it was too late and i hit a signal light pole, also airbags didnt deploy.

Here are some pics of damage

You deny the impact of the method of advertising used? Don’t be dense.

You’re assuming I’m speaking of the engineering of the CT, which I assume is constructed well and passes standards. My point is directed at the behaviors of the drivers.

And here we are, complaining of ghost braking and too sensitive, too-hard and sudden situational braking.

 

[Peterwtf]

After driving my CT for a little over 500 miles, I’m happy to say, I’ve had no issues so far. But, like some of you mentioned, when I had to brake hard all of a sudden, it took more pressure than I expected. Not any point of near collision, but realized this is not a Model 3

 

[MajorVictory]

The OP and others are correct to bring attention to their experience and concern.

it should not so quickly be denied or explained away.

i have had a similar situation where what i believed to be max or near max braking was surprisingly weak. Worse than id expect all considered.

Yup must be a defect. Felt exactly like brake fade at the track but the cruising at 70mph on the highway is no track.

I know what brakes should feel like on high performance cars and trucks. Had em all. Ferrari’s to 3500 dualy trucks.
My other current car is a Landcruiser i built for taking off road. Full steel under armor, rock sliders, steel full roof rack, roof tent, steel swing out tire carrier. Basically It weighs as much or more than the CT and would have made the necessary stop.

I love the CT so far. No false narratives being created. Im just concerned that my CT may be defective. I pushed the brakes and not much braking was happening. Pushed harder and harder and nothing. Couldnt even make the wheels skid or ABS go off.

Maybe it was my driving position idk. I was pretty relaxed. But Im not new to driving. Probably the reason i was able to steer away before hitting.

Apologies, I thought you were saying something else. Upon reading your post, I can't even see why I thought that!

My mistake.

Have you created a service ticket? I mean this isn't rocket science. If I thought I experienced a braking anomally I would take it to an empty road and put it through some brake testing. I mean, either it engages the ABS, you feel the pulsing in the pedal, and the truck stops as fast as traction allows, or it doesn't. I would immediately know if they were working as designed or not.

There's nothing new or revolutionary about Cybertruck brakes.

The problem I have is people saying the brakes are simply too small and don't have enough stopping power for an emergency stop. I think they are just used to power brakes with much heavier boost, giving a lot of braking for a very light touch on the brake pedal. Even if the Cybertruck had much smaller, much less powerful brakes, they could bring the tires to the point of lockup one time.

When Carwow tested the stopping distances of the Cybertruck and the highest spec F-150 made, a Raptor R, they found the Cybertruck stopped in a shorter distance:

Unless proven otherwise, what I think I'm seeing is an attempt (by some people) to take the shine off the Cybertruck, to make it less desirable. it's done in many ways, like implying that the stainless steel has a rust problem, that the brakes are weak, that it's more dangerous to pedestrians, that it's not a "real" work truck, etc, etc, etc. Whatever they think will resonate negativity.

No Tesla model requires the help of regen to make a traction limited emergency stop from 80 mph without any regen assistance. That includes the Dual Motor Cybertruck. This is just basic automotive technology, the discs are powerful enough to bring the tires to the limit of traction on clean, dry pavement.

Im the OP. I love the truck. Just stating my experience to see if anyone else has felt the same thing.
Its not rocket science. I wanted to go out and test it but ive for a lot of stuff in the truck bed I need to move tomorrow that would not take well to hard 70-0mph stops.
The truck is new man. Theres bound to be some issues. You cant be overprotective and dismissive about what people are experiencing. Especially in a forum where i think most of us are excited to have received our trucks. If anything, this forum would be a way to communicate issues and maybe get fixes from Tesla before it shows up on the news devaluing our CT’s.

 

[swinefeaster]

I've noticed my ct brakes are a bit weak too. I thought maybe they were just not broken in yet. I will teast it out somewhere safe with hard stops and report back
