How do you really determine ur brake setup is more effective?

[fueltank]

So would upgrading to a bigger brake master cylinder on stock DC5R calipers give you better 'stopping power'?

What is stopping power? The amount of force the calipers can squeeze the pads on to the rotors?

if shorter pedal travel = better stopping power

(ie the pedal travels less distance with the same amount of decelaration)

[tinkerbell]

as close to "stoppign power" definition i have seen:

Braking torque
Braking torque in pounds feet on a single wheel is the effective rotor radius in inches times clamping force in pounds times the coefficient of friction of the pad against the rotor (a unit-less value) all divided by 12. Braking torque is the force that actually decelerates the wheel and tire. To increase the braking torque it is necessary to increase the line pressure, the piston area (clamping force), the coefficient of friction, or the effective rotor radius. Increasing the pad area will not increase the braking torque.

Ahhhh so from that we can say that brake caliper stiffness and its piston sizes would allow aftermarket calipers to have better braking torque then say oem calipers

sounds right.. but what is brake caliper stiffness? eheheh

I would allow for more factors..

Large diameter disc.. for some kits
larger pad size .. for some kits
more pistons
larger pistons

[BlitZ]

another can of worms..

I can get larger diameter disc and relocate caliper to outter edge....

does this contribute to more stopping power?

yesh... but more clamping force? No..

[Jingers]

i guess monoblock calipers are stiffer? so confusing

[Jingers]

More leverage right? Just like say if u were trying to stop a SLOW bike wheel by sticking your fingers close to the hub or outside its much easier been outside

hahaahah yesh..

But on the outside your hands will most likily overheat..

you will need better cooling or high temp gloves...


There are kits u can buy to relocate to outter edge.. and from memeory its only a few hundred smackaroos

sheesh! READ the Stoptech links i have posted above please!

here is one on caliper relocation:

What is this in laymen terms:

"The equation above assumes a perfect embodiment of the caliper
clamping function. In actual fact, the more compliant (or less stiff) a caliper is, the less efficient or able it is to
maintain a 1:1 ratio of system pressure increase to increase in force applied perpendicular to the pad face."

only makes sense if i replaced the word caliper with lines or piston valving

[tinkerbell]

laymans terms: "caliper stiffness determines braking power"

eg. a billet 6 piston caliper is more stiff than a cast 2 piece 1 piston caliper

therefore it can exert more force due to not bending when being pushed by the brake fluid...

this allows more constistent overall friction (on pad area), leading to more deceleration over time...
