DIsc brakes use brake DISCs

Warwning, rant mode is ON!
Why on earth do people insist on calling brake discs 'rotors'?
The DISC break was invented in the UK (Dunlop), when the US finally decided their cars needed brakes (instead of the breaks that came with drums) and adopted discs they called them rotors, when they put disc breaks on bikes they used the same word, but that doesn't mean we have to slavishly follow the americans and use a different word to the one we used quite well for 50 years.
People who call them rotors don't go to the 'restroom', wet their 'pants' accidently due to the 'fawcett' or have 'fender benders' in their 'automobiles', they don't put kids in 'diapers' or send them to 'kindergarten' (German of course to start with) or walk on the 'sidewalk' so why call the [expletive deleted] things rotors? (wouldn't that make it a 'rotor brake' not a disc brake anyway? - Oh sorry the american's never had any logic)
Lets reclaim the word DISC and be proud to be English and to live in the country that invented them!

What is this disc break you speak of?0

i've just always assumed they were called rotors, i've never called them discs.
does that make me a bad person?

What if they're American brakes? Then what do we call them?A Flock of Birds

Simon - you were on about this a few weeks ago.
Give up.
Rotor/disc/whateva.
If you say disc I know what you're talking about and the same with rotor.
Although if you say you have rotor brakes I might get the idea but not be sure if it not something new.0 -
The are two common brake designs, these are drum and disc
Brakes do not "come with drums", the drum brake is a design type
Drum Brakes comprise of four primary components
1 - The Master Cylinder
2 - The Slave Cyclinder
3 - The Brake Shoe that also contains the Friction Material
4 - The Brake Drum
Drum brakes offer superior perfomance over disc brakes, that's why trucks use them, due to the larger braking surface of the drum design. However they are prone to overheating when over stressed. They are also considerably heavier than most disc designs
Disc or "Disk" Brakes comprise of 4 primary components
1 - The Master Cylinder
2 - The Caliper
3 - The Rotor
4 - The Friction Material, aka brake pad
Disc brakes offer superior braking in lightweight applications like cars and bikes. They are easier to cool (vented/slotted) lighter and easier to maintain
In the automotive industry the rotors are often termed as discs, however I have heard them called rotors in the motorcycle shopsThe Beginner wrote:Lets reclaim the word DISC and be proud to be English and to live in the country that invented them! Simon
As a former US resident I'd like to inform you that their language and grammar may differ from ours, but at least they can spell, unlike you who does the English language no favours at all!
If you want to "rant" get your facts right. It sounds like you woke up hating the Americans and nothing else..0 -

No the Disc Brake as invented by Dunlop, item 3 is The disc....its only the americans when they finally copied it that chose a silly name!Raymondavalon wrote:Disc or "Disk" Brakes comprise of 4 primary components

2 - The Caliper
3 - The Rotor
4 - The Friction Material, aka brake pad
calling 2 the calliper is misleading anyway, as contains many parts, the wheel cylinder(s) for example
The rant really is over the adoption of what is an american word unnecesarily....its a disc, its shaped like a disc, in the car world no-one in this country calls it anything but a disc, so why do we use the american word when we don't copy the others (even bike related)......

They should be re-named stopping circles.0

just to remind you this is not a UK centric web site.
so people use what they use."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Hmm I think it is UK Centric (as in the vast majority of contributors are Uk based), although clearly not exclusively UK.
Most users on here who use the 'R word' are UK based..... however if a US or 'English (US)' user as MS who have it used the word I would have no issue.

I see there is a reason why you are called the beginner.
Rotors is in fact the name of the disc. Whether you use that word is up to you, but what makes it so bad if someone else uses the word. Are you really that concerned with what people call the round thing on their wheel for stopping?0 -
You clearly have to much time on your hands, get a life !!0

What a knob head.

That is the point though, it's not, rotor is an emrican word for what the original inventor called a disc - besides saying 'rotor is the name of the disc' is contrary as you just called it a disc! however I guess you feel free to comment without actually reading the text?
The beginner I used because my usual nom de guerre for forums means similar and is taken on here, suspect I know more about brakes than most of you.
Bennet, your name should be Just-in, why the need to resort to abuse, unless of course you have nothing intelligent to add - oh tha is it, nothing intelligent to say, so lets be abusive - Duh!
I don't mind having reasonable conversations with those who wish to be reasonable and constructive (even if they disagree), the ones who can't comment intelligently please feel free to go elsewhere!

It wasn't the most intelligent post to begin with. The amount of spelling and grammar mistakes on your part is rather ironic too.The Beginner wrote:Bennet, your name should be Just-in, why the need to resort to abuse, unless of course you have nothing intelligent to add - oh tha is it, nothing intelligent to say, so lets be abusive - Duh!0 -
Simon, your English isn't that great considering you proclaim to be the warrior of things English. Uphold true grammar in your posts before attacking the slippage of Americanisms.0

Quite rich for an English language pedant :roll:The Beginner wrote:The beginner I used because my usual nom de guerre for forums means similar and is taken on here, suspect I know more about brakes than most of you.
Rotor is an English term for something that rotates. From turbines to windmills, to motor stators - they can all be called, correctly, rotors.
As far as MTB brakes go, what's the bad point about calling them "rotors"?
When people say they're after buying some discs for their bike, they are frequently referring to the whole package of the braking system, such as "hydraulic discs".
But when they want the specific part, it is common to refer to it as the "rotor".
Seems to me it helps dispel any ambiguity.0 -
Where does it say I hate the USA, 2+2=5 there, I have no issue with the USA at all, my issue is with what I see as a misuse of English, how that translates to hating the USA is beyond me (and why the unnecesary insults again or do you suffer the same condition?)

I suppose next you'll be trying to tell me the correct meaning of "ironic".
I reckon you're just a troll, you seem to keep coming out with this stupid internet bravado just so other users like me will react.

Oh, and Disc brakes were not invented by Dunlop, as far as I am aware.
I also seem to recall that on cars at least, they were more commonly found on American road vehicles long before British ones.0 -

Invented in America:
"This is ironic, because the spot-type disc brake is an American invention. In 1898, Elmer Ambrose Sperry of Cleveland designed an electric car having front-wheel disc brakes."

But the thing is, it is just in the shape of a disc. That doesn't mean it's official name is a disc. The whole system is a disc brake system, because the stopping parts are in the shapes of discs, but they are called rotors because that is the name for that part of the system.0
