The Story of Brakes

Too bad they didn't *stop* us from polluting the planet and ruining urban life.

Ba dum tiss!

Fantastic video. 1.1megawatts disspated by the Regero at the beginning of the video seems a bit much. Maybe an error in the units?

the brake manufacturers must develop rotors that act like regenerative energy devices...

1.1 megawatt for one home for 2 hours? I highly doubt that, unless the average american home is some huge industrial facility.

Here's a (slightly) interesting fact. ABS is actually German, meaning "Antiblockiersystem." The English phrase: "Anti Lock Braking" is just a nicely fitting backronym!

Zzzzzzzzzzzz… bore the skin off a rice pudding

The joy of owning an EV

I think you skipped engine breaking.

As a former technician of Chrysler I can honestly say that they do not believe in brake fluid replacement, you will not find it anywhere in their maintenance schedule unlike every other manufacturer in the world 😂. Secondly my apprentice tells me that the terms master and slave cylinders are no longer permitted in school and are now referred to as primary and secondary cylinders.

I learned a ton! Thanks!

Thank you for making this video learnt a lot

1.1 megawatts of power?
Just what kind of American Home are you thinking of?
1.1 megawatts... That would be more like 10 days of power...

Stopping is more important than going fast ... I guess. Not as fun though.

What a wonderful video!

Great video. What I still want to know is, when lightly braking on a regenerative system, are the brake pads not yet in contact? And only when braking harder, they engage? Very curious.

drum brakes are pain in the ass to disassemble and assemble those tiny strong ass springs are so strong to strech

Why does the narrator sounds so fucking stupid and nasal?

Do steel braided brake lines increase braking capacity under heat and pressure ?

Great explanation 👌

War - Wooden Brakes
War - Rubber Brakes
War - Vaccum Brakes
War - Disc Brakes

We don't need innovation, we need wars.

Air breaking ...??

Gotta harness that braking energy to power ev and hybrid vehicles

I don’t know about these fancy breaks ur talking about, I’ll stick with good ole block of oak for all my stopping needs

New title: “A Break down of Brakes”

can’t believe their inventions is still the parts that we use today. how smart is this people back in the day

I just upgraded my 4Runners brakes to larger tundra brakes that fit and man what an insane difference a good set of brakes are on a vehicle. Especially a heavy SUV. stops on a dime now but also makes cornering and everything easier to control. A get set of brakes get you in tune with modulating the vehicle’s speed. Just makes the experience so much better.

I farted today enough to power a vehicle for two hours.

Today I learned... This content was missing from my life!

If I did brake jobs for a living my motto would be " We stand behind our brakes but we won't stand in front of them"

That is an excellent video and should be used in training new automotive engineers (if it is not already being used that is) If used in the UK a very minor observation to the otherwise excellent commentary is that some terms need to be put across in a dual way such as 'Rotor' in the UK would be 'Disc' and both terms should be learnt as it gives a wider learning scope (understanding other versions of component names is important I feel) Really enjoyed it, great work!

Thanks for the topic. People always talk about improving the "go", and not about improving the "woah"

Interesting

"knots per hour"??? No.

Thanks

I'm very impressed with with research and detail given to the mechanics and design of things as menial as the caliper piston seals. That's dedication to quality information

A return spring was an incredible invention.

Well, this video stopped me dead in my tracks! Well done!

Drum brakes have advantages for Hybrids, and large cargo trucks use them.

I wish I had this video when I took an auto shop class 30 years ago. 🧐

brakes are for covards.

Absestos was the infamous material used for braking cause it was able to resist heat so well. The problem was that people were getting sick because of the dust it created and when breathed in, it would attach itself to the inner lining of the lungs, causing breathing problems and form tumors, causing what we know as mesothelioma. We start to see the increase of semi metallic and ceramic brakes once asbestos, a world wide insulating material was being banned.

Drum Brakes are still even in 2024 Effected by Water Ingress and yes some new cars (small kei cars and small hatch backs) still have drum brakes in the rear.

I Remember our Old Toyota Hiace Van in the 1990's (1970's model) when rear drum brakes got wet in puddle on our driveway when it was flooded, would majorly reduce braking ability and cause the nose of Van to dive majorly under braking as only front discs were working then.

So would have to RIDE the Brake pedal for about 1km after hitting a big puddle as it took ages to cook off the water in the brake drum so they worked properly again...

Also Drum brakes don't work well when in Reverse (handbrake works as car not moving, but if you get it rolling then engage rear drum hand brake it would slowly slow down n come to a gentle stop so not good in certain emergencies.
(if you have 4 wheel drum brakes and say stall climbing a steep hill, if you dont stop car instantly it would start rolling and then no way to stop it if hill too steep, This was a common accident cause in the early 1900's on cars mostly light trucks n utility vehicles.)

Electric Brake motors are also how Tenpin Bowling Setting Tables or Pin tables(which are the large "trays" that hold the pins & place them) Are slowed down to a smooth slow speed when placing Pins so they don't wobble and fall over, while releasing them very quickly (with big long "Belts" which are really just big rubber ropes heat welded together, which often fail and table might fall or get stuck uptop, but often not in some in between position as the Brake Motors are the only thing holding them up when in transit so if they fail or belt snaps tables drop with a large force as they can weigh well over 150kg.

These "brake motors" work on same principle as Regen Braking in EV's, althought they don't harness the energy generated but instead dump in into giant Resistors banks with capacitors they just let the produce energy dissipate as heat and other losses.

Tenpin Bowling Pin tables have used these electric motors for near 100 years if not more,
(- Former Pinsetter Mechanic)

The inboard disc brake system on the Jaguar,
is also designed so that a car can be put over
a grease pit, and change pads without jacking,
or removing the wheels. That is for endurance
racing. Driver parks over the pit, a mechanic
changes out the pads, in a very few minutes.

ABS doesnt provide best braking performance. Rather it allows braking while still having Control over steering and reduces tire wear. An expirienced driver without ABS will always outbrake an inexpierienced driver with abs

Outstanding, excellent content. Really enjoy the mix of history and technical explanation.
