well... brakes are not as engines in terms of heat... it depends on your driving style and road conditions... i have managed to deform the plastic wheel covers and smoke the pads to oblivion during city driving... it was more "insane city driving"... on the other hand i touch the brakes once or twice on a 55 kilometers trip to work on the highway... basically the brakes will be just COLD
their is no ideal temp for brakes when it is used... it is so various due to difference in driving conditions and driving style.
then i thought if you increase the pressure of a fluid, you increase the boiling point...?
you got that right so supposedly at 10k PSI during braking would increase the fluid's boiling point (brake fluid + water mix) so it probably wont boil at the first high temp braking... once you release the brake pedal you are back to normal pressure (the braking system @ atmospheric pressure when you don't apply the brakes) so you are back to standard boiling points for both the brake fluid and water
since heat will not disperse as fast as the brake pressure then the hot components will keep on heating the fluid and it might start boiling and that will produce gas bubbles inside the calipers... i recon you can imagine what will happen during the next use of the brakes under the current situation
or is this only the fluid at the caliper?
the most affected area with the boiling process is the fluid in the caliper as it is the area were all the heat is generated.
