I did a search and did not find anything on this subject...

Does anybody know how the fade compensation works? I know what it does, but am curious how it actually works.

Thanks!

I don't know hot it works but If had to guess I'd say there is pressure amplifying factor that is calculated based on how much braking was done in the past X minutes.

Another possible way this could work is for a given deceleration the computer knows how much brake pressure the driver has to apply, if the driver is applying more pressure than normal to achieve that same deceleration then the brakes are fading so the brake boost pressure is asjusted.

Thermal Sensor.

From what I have read (I forget where) as your brakes heat up and start to fade, a sensor applies more boost to compensate, so the pedal feel is the same, ie. same travel, and firmness.

hhhmmm...so the consensus is that there is a temperature sensor somewhere in the braking system? I just can't see any other way for that to work effectively. So if there is a temperature sensor, then there has to be a way to vary the pedal pressure electronically, right?

Yes, and I have felt several electronic friction points so far. This car's brakes DO have a mind of their own and will grip and bite more aggressively if you are aggressive with the pedal.

If you are normal driving they will feel normal and relaxed.

Under certain conditions they will apply sooner and with more force with the exact same amount of pressure as used in a normal situation.

I believe some of those conditions are, an abrupt lift on the accelerator, a hard initial press of the brake pedal, or a sudden increase in brake force once brakes are already being used.

If you press the brake pedal in a slow, linear manner, you will feel a more relaxed application of the brake for a given force on the pedal, as opposed to a firm and aggressive initial pedal appication, which yields a harder clamping from the system on the rotors with the same amount of force applied in the above scenario.

I hope this is making sense, as I am drinking wine, and an on my second glass, LOL

Anyways, there are quite a few sensors that "tell" the car how much and with what amount of force to apply the brakes at.

Sometimes I like it and the system design parameters works flawlessly, and other times it makes driving smoothly a bit of a challenge

Cheers all

I wonder if this system has anything to do with some people experiencing limp mode at the track when their temps appear normal?

Have any of you changed to a BBK? Did you find a temp sensor on the OEM caliper?

I have to look on the OEM caliper..but my guess is there isnt one.
