Revelation about brake shoes

This is Triumph-related, inasmuch as I saw this in a listing for brake shoes for a Herald on eBay. I was particularly struck by one statement in the ad:

<span style="font-weight: bold"><span style="font-style: italic">XXXXXXX brake shoes convert the pressure from the wheel cylinder into heat and friction and facilitates stopping of the vehicle.</span></span>

Really? Is this something new...or just maybe <span style="font-weight: bold"><span style="color: #990000">ALL</span></span> brake shoes do this? Am I missing something? :confuse: :confuse: :confuse: (I'm not even going to mention the grammatical error in the above statement! :devilgrin: )
 
It's friction that stops the car...heat is a byproduct.

If heat stopped your car, nobody in Phoenix would be moving.
 
Another way to look at it : brakes work by converting kinetic energy (motion of the car) into heat. Friction is the mechanism that performs the conversion. And pressure from the wheel cylinder is what modulates the amount of friction and hence the rate of conversion (ie how quickly the car is slowed).

Andy's quote, while tangled, is basically correct.

Most likely, the author of that quote does not speak English as their first language. Although she is studying hard, my Taiwanese wife probably wouldn't do any better. You might say, I recognize the symptoms :laugh:

Dangit! That's why my TR8 isn't working! I live in Phoenix!

Heh.
 
The lister has a keen sense of the obvious.
