# As Mentat said, it doesn't change the pressure exerted on the rotor... The same pressure is applied farther from the center point to provide more torque to stop the car. nm

: There has been many times when I've used a cheater pipe for more leverage, but that's related to a lever type action not a clamping type like the calipers and pads. I don't see how putting a caliper out futher will increase the pounds per square inch force needed to stop a rotating mass, since we're dealing with a clamping force instead of a lever/pivot type force. As you're aware there are many different factors that can effect the force applied to the rotors. Everything from the dia. of the master cylinder, caliper and wheel cylinder pistons, also the length of the brake pedal (which is a lever) If the caliper/pads remains the same the force applied will also remain the same. Isn't torque a twisting force, I just don't see how torque is a factor in our braking system. When diagnosing severe brake problem most service manuals will ask you to install a pressure gauge at the caliper to see what pressure you're getting, times that by the square area of the pads and you get your psi. Again I just don't see how torque (twisting) is a factor in our braking system
