brake fluid flush

[thstone]

Interesting. I do ~25 track days a year and heat the brakes to the point of smoking on a somewhat regular basis yet only do a fluid flush every year and never have a problem.

Occasionally, I experience "pad fade" where I have to exert much more pressure than normal to get the car to slow down but the braking performance recovers to normal after the brakes have cooled. What symptoms are you experiencing that points to boiled brake fluid?

Interesting.

Are these PCA events?

How do you properly pass tech inspection, with only a yearly brake fluid flush? I know our Chicago Region PCA requires a brake fluid flush between track events to properly pass tech inspection and the form that is signed by the driver.

Brake fluid absorbs water but with only the small surface of the Brake fluid reservoir and capped at that, where could all this water be coming from that the fluid is absorbing?

Just asking. I always thought that air bubbles were the culprit of a soft pedal.

Boiling the fluid is another matter and I thought those antisqueel pads served dual purpose of insulating the pistons from the source of heat (Brake Pads) and hence prevent boiling the fluid.

A good supply of cooling air could also help that situation which I read can be improved by installing the Carrera 4 front brake air directors.
