Correct, but when it's pulling away from the stays, the only thing keeping it there is
the mounting bolt. * All the stress of the braking is transfered through the mounting
bolt and nut. The bolt itself bends and is not inelastic. And the hold that the bolt
goes through is not perfectly flush with the bolt. *But on the front brake, the entire
brake caliper assembly is being forced into the frame which is for the most part
immovable and thus gives better stability.

I get a ****ing headache every time I read that. *I don't have my
stupid-to-English translator engaged, so tell me this, Batbuoy, are
you arguing that a loose brake bolt is what makes the difference? If
not, and the braking force is the same, as it must be, and all braking
force is transmitted to the frame, as it must be, where does this
extra braking force come from? *The bolt, submitted to the same force
in either mounting position, will deflect the same amount as the
difference in geometry is negligible. *Much like your argument.

No no no no. *The front brake transfers most of the force through the mating surface of the
caliper to the FORK. *The front bolt transfers probably 30% of the force. *On the rear brake,
the bolt transfers nearly 100% of the force. *It is true that all the force is ultimately
absorbed by the frame. *But the design of the front bake via its placement on the front of the
FORK makes it a more stable design under high loads and high speeds.. *Ask any frame
builder/engineer.

Harry Havnoonian is a frame builder AND mechanical engineer (degree from Drexel). *He mounts
the rear brake in front of the seat stays for this very reason and has been doing it for over
20 years. *Give him a call and he'll tell you why:

Jesus Christballs.

When a bike moves FORWARD the top of the rim
is moving FORWARD and when you brake, the frictional
force of the rim on the brake tries to pull the brake
FORWARD. *You appear to be pedaling your monkey-bike
BACKWARD. *Are you a fixed gear hipster, or worse yet,
a trackie? *What do trackies know about brakes anyway?

Listen up. *The bolt acts as a fulcrum *So when one end of the seesaw goes up the other must go
down. *It's a physics equation.

You would not know a physics equation if it ran up and tore your face off..

Which of the following are physics equations?

H Psi = E Psi

I_zx = int rho(x,y,z) dz dx

v = (V + v')/(1 + V.v'/cc)

* *d *@L * @L * * * * * *dq * * * *
* *-- -- - -- *= 0, *v = -- .
* *dt @v * @q * * * * * *dt

div E = 4.pi.rho

How many other engineering schools have that same stupid cheer?
One thing about engineers - they're not often the most creative lot,
and they like to steal other people's work. This is how I know Nim
isn't an engineer. He just makes up **** as he goes along.
