Cooler Brakes : How Tos?

[Violator]

@audios

can you explain this to me in more detail? i could understand the bias being effected by not changing both rear and front rotors in porportion. but how does chaning to a larger rotor in the front, without upgrading the caliper/piston (i think what you are implying is the load seen by the caliper). the clamping force of each caliper at each corner is static, therefore the only real variable can be the effects of that clamping force at each individual corner. eg having three street pads, and one track pad. the track pad having more bite will effect the grip, without any change in the pressure on the rotor via the caliper assembly.

I may be wrong but I believe a larger diameter rotor changes the moment and increase the resulting stopping torque.

In any cae to increase brake performance you need:

better pad material: Hawk or Pagid

more rotor material: IE THICKER rotors

increase swept area: surface area of calipers in contact with rotors

larger diameter rotors: more brake torque … more rotor material(assuming thickness is not reduced)

Multi piston calipers: you dont necessarily have to change the master cylinder out… there is some room to work with

Any of these changes other then thicker rotors will change your brake bias.
You always want more in the front. If you are not sure always bias the front more even if its wrong. Its MUCH easier to control/recover a car with front lockup then one where the rear locks up first and you are spinning across the road.
