Disk brakes? Hot!

They only get hot the first couple of times. Try again in a few days.

Hello everyone.

Kinda new here, been reading the newsgroup for about a week or two.

Just bought a new Specialized crossroads bike with disk brakes. I was

riding

Quoted message said:

down a hill earlier tonight, It was pretty steep grade so I had the brakes
on all the way down, about a full minute give or take.

I was wondering if the disk brakes got warm after having them on for so

long

Quoted message said:

so after I got down to the bottom of the hill I did a stupid thing. I
stopped, got off the bike, and touched the disk. I almost burned the skin
off my fingers, they were like 400 degrees.

Is there any warning I missed about not touching the disks? Is there a

limit

Quoted message said:

to how long I can brake? Will long braking sessions cause damage to the
disks or brake pads?

Thanks in advance.

Nice Jerry, that's what you should tell the kid. Yeesh :-)

They get hot and long braking won't hurt them, they won't fade very much in
my experiences. Some will, but the good ones should not. They get hot!!!
Some moreso than others, I have Hayes and Shimano and my Hayes heat up
easily compared to the Shimano's. The best part is riding in the rain and
then listening to the raindrops hitting your disc after a long decent, ahhh,
biking. It's been a long winter I can't wait....

Yeah, it's right next to *that* other warning sticker about not storing
double edged razor blades in your underwear.

Oh.......you've done that too? 🙂

I learned quickly never to do that again.

It's called friction! Rub your hands together and tell
me if they don't get warm. Same principle.

the warning is kind of inclusive under the main heading in the book of life

Brakes get hot; don't touch them. Don't stick body parts in the chain or
the spokes. Do not wreck. Check your front tire mount often. Do not
attempt to remove a leaf which is rubbing a tire.

There. You've been warned. 😉

There IS a limit to how long you can brake, just like in a car or any other
vehicle which uses friction brakes. You'll know when you've hit the limit:
they simply stop braking no matter how hard you apply them.

Just like in your car (if you are yet of driving age), you can indeed cook
the brakes, thereby shortening their life. That's why they make
replacement parts 😉

See there all you parents out there, this is what happens when you protect
your children from "unsupervised playtime". You get a whole population of
adults who expect everything that they touch to behave like a Fisher-Price
toy. No sharp edges, hot surfaces, etc.

See, life isn't like that. There's sharp, hot, caustic, dirty, and otherwise
unsafe stuff EVERYWHERE. If you don't learn that before you leave high
school, when do you learn it?

When I was a kid, my parents literally sent me out to play with a can of
lighter fluid and a box of matches. And I turned out OK.

You going on the Absolute ride today? Just leave the lighter fluid at

Was this by any chance right after they took out a life insurance policy on
you?

Yeah, much to their chagrin! 🙂

Well, talk to any old timer roadie about sewups. They're glued to the
rims; too much braking and the glue melts and the tire comes off.

Sewups make for some seriously fast descents....

As for your question, where does the kinetic energy of you+bike@some high
speed go? Into heat. The only way you dissipate that energy, short of
hitting a large fixed object, is by converting it into heat. Rims get
warm; they have a larger surface area. Disks get hot; smaller surface
area.

And as for the warning, wasn't the yowling you heard warning enough? Will
you do it again? :-)

Agreed. I am not that way with my son at all. I think that plays into why
so many Americans are sue happy.

Who's got that photo of the glow in the dark disc rotors that was posted
ages back?
Was that one of your's, Slacker????
It was a night-time photo of a blurry bike and you could see the rotors
glowing orange!
