When I was a kid most of us had bikes with 2 or 3 speed hubs where a slight backpedal changed gears and a harder backpedal braked. Most of those bikes had no hand brake for the front.
Drop or break a chain and no brakes.
I never recall that happening, but it is something to consider.

1.) Fred Flinstone style.
2.) Wait until you land/stop rolling across the asphalt, pick yourself off, check for injuries, check for bike damage.

When I was a kid in the mid to late 60s my early bikes had coaster brakes and one speed. I recall on 2 different occasions when the chain came off the chainring, resulting in NO brakes, and both times going down a hill that ended in a cul de sac. Wiped out both times!
However, with HAND operated brakes I have always been able to stop. I did have a cable break, but I was still able to stop.

It's interesting that you've brought this up. I used to ride downhill and singletrack/crosscountry MTBing, and not once did I worry about brake failure. Now that I ride as a commuter/utilitarian/recreational road cyclist, I am always nervous when going down a hill that something will cause the bike to seize and I'll be flung off the bike. I think its just my paranoia, and the fact that my invincible years are coming to an end, but it was an interesting realization. Brakes were definitely important while racing down mountains and launching myself off cliffs, something about the pavement makes me feel like it would hurt more to land there...

Regardless the whole thing about tires blowing is completely unrelated to brakes stopping a bike.

I think it is important to maintenance your bike to make sure everything works correctly, especially if you regularly cycle fast. As for breaks, I trust my V-brakes. When I need to brake, I usually do so smoothly and from a distance which gives me plenty of time to maneuver out of the way if they would not work for some reason. Though truth be told, I did get into the bad habit of using my back brake later, at higher speed and more aggressively, making my bike slide a little. I should probably stop doing that, people just think I'm a jackass for doing it, though it is just childish playfulness.

I haven't heard of a brake failure due to defect, however there is one issue I haven't seen mentioned yet.
On a long descent with a bike equiped with rim brakes, it is possible to overheat the rim and cause a high speed tire blowout, which at high speed this could be deadly, especially if it's the front wheel.
It's one of the topics covered in the book "Bicycle Science".

Here is the report of a recent tragic accident.
"A teenage cyclist was killed after the brakes on the kit bike he had built from scratch apparently failed as he rode down a hillside with his father and sister, sending him speeding towards a busy A-road where he collided with a van."
The victim's father blamed the bike shop's work on the brakes hours before the accident.

That's been going on in freestyle, since the mid 90s. It's become so common, that not only are most forks no longer made with brake lugs, but a lot frames are being built without them, as well.

Does it really seem, based on news articles, that there are 30,000+ motor vehicle deaths in the USA each year. I certainly have not read 100 such articles each and every day.

She asked a valid question. Got responses. Then she found a case that adds to the thread. Then you act like she has been doing an unending search all this time. Your response to her seems off base to me. The number of news articles is not a got indicator.

You'd have to know more about that incident. It said he "built the bike up from scratch." What does that mean? Did he grab some crappy brakes off of an old Huffy bike, or did he buy new brakes? What kind of brakes were they? The father said that the bike shop worked on the brakes hours before. Does he KNOW that they worked specifically on the brakes, or did they work on something else? Did they inspect the brakes, and if so, what did they say about them? It's possible they looked at the brakes and told the kid "these brakes suck, you need to fix them" and he said "meh, whatever" and never told his dad. Did he have two sets of brakes, or was this a single speed with coasters, or a fixie with just front brakes?
We just don't know. Without this information, it doesn't really add much to the discussion.
Truth is I trust the brakes on my bike at least as much as the brakes on my car, because in 5 seconds I can inspect everything that there is about the brakes that might fail, and if there's the slightest thing wrong I can probably feel it immediately when I'm using the brakes, far before it becomes dangerous. AND there are two completely independent sets of brakes on almost all bikes.

The Long Haul Trucker isn't particularly suited to fixed gear but I guess it could have been.
I'm just glad I've put in many miles on brakeless freewheel bikes so feel fairly confident braking without brakes.

What if your car accelerator stuck while going 70 mph? What if your car brakes failed going that fast? What if, what if? Life is too short. Check your equipment before riding and just enjoy the ride.

Yup, the world is full of what if's, I say so what? Don't live your life in fear of the what if's, but live it instead to the fullest.

Bicycles are equipped with 2 independent brakes. this redundancy makes it nearly impossible to have an accident caused brake failure alone. Granted, the failure of one brake can increase the braking distance leading to a possible accident, but even this is unlikely if the rider rides in control.
The accident described in the UK newspaper happening because of brake failure is unlikely almost to the point of impossibility. It would have requires total failure of not one but both brakes -- such as might happen from shoes falling off, or cables breaking. Either brake alone would have been enough to prevent runaway acceleration even on a super steep hill.
I'll venture that a forensic examination of the brakes will show them to be functional, and the actual cause to be a form of user error.
BTW- user error due to panic is far more common that you might think. Both adults and children, on bicycles and in automobiles, often crash simply because they never even tried to apply the brakes.

Many, maybe most of your questions were answered in the linked article.

As I said earlier, the chances of total failure of both brakes are super remote, so one has to wonder at what else isn't said.

No, in fact they left more unanswered. Since the child was described as standing on his pedals and screaming, I have towonder of this was a first bike with hand brakes, and in his panic he tried stopping it by foot as he would with a coaster brake.

Really, you guys cannot read the article to answer some of the questions by ItsJustMe. OK lets go slowly now!
The father said that the bike shop worked on the brakes hours before. Does he KNOW that they worked specifically on the brakes, or did they work on something else? Did they inspect the brakes, and if so, what did they say about them? It's possible they looked at the brakes and told the kid "these brakes suck, you need to fix them" and he said "meh, whatever" and never told his dad.

I missed where ItsJustMe asked that question in the post that I responded to. Can you point to it?

You're taking a bunch of buttons and sewing a vest on it. Yes, it was a LHT, and I know it came with 2 hand brakes. Yes, we know the shop replaced one cable, and yes, mom owns or manages some retail bike shops, but the article implies she was still in the USA at the time.
I didn't imply that I thought your response was directed at me, just that I had similar questions to those raised by Itsjust me.
What isn't answered is why the child accelerated away form his dad on the descent, why he was standing, whether he was, in fact, applying or trying to apply the brakes, how steep the grade was, the time and distance elements, the child's experience with hand brakes, and so on.
All we have is a bunch of facts, but nothing that strings them together well enough to form a theory. I don't know what policy is in the UK, but here the police would have impounded the bike, and at some point tested the brakes to see whether they worked or not.

The article says the family moved back to the UK. Do you not consider Mom part of the family?

As it is, there's no mention either way, and it isn't germane to the issue except that you raised the issue that mom would know how to adjust the brakes, though it is possible to run bike shops and not know anything about bike mechanics.
