Brake system
Hi,
taking my E63s on trackday, just wanted to confirm that out cars don't have brake by wire system right?
Asking because in case of brake fade, I should feel pedal getting softer and pedal travel getting longer as a warning size before I lose brakes?

Nope...your Brembos will be fine, hot and dusty... unless you are an A+ driver more than sufficient, even if you have OE pads. Better if you have EBCs.

If you feel your brakes fading, you need to exit the track immediately. Track officials should be doing brake inspections prior to allowing you to drive. High temp brake fluid is not a bad idea either.

Yeah ofc, I think I was even overreacting a bit, as soon as I felt my pedal getting bit softer I would just abort the lap the go for a cooldown lap, thinking its better than losing breaks 
Car has some much potential, I was limited by having at max 1 attack lap before brake fade, but I will be doing brake lines + RBF 600 before next track day which should help a lot

If you left-foot brake on the track like many experienced track drivers do, expect your brakes to take a beating -- inspections before and after each track event and frequent fluid changes

there are exactly zero cars with brake by wire.
For safety reason, all cars are either vacuum assist or electric assist with assist being the operative word. If any of the assists fail, there is a hard link between the pedal and the brake piston.

It's worth mentioning that parking brakes have become electric actuated (brake by wire), but this is not the primary braking action as you point out. The ABS assist integrated into the hydraulic system and electric park braking do add confusion to the discussion. For example, which braking system do collision avoidance systems use? Is the electric parking brake deployed if there's a loss of braking action in the hydraulic system? I don't know the answers without researching, and I don't recall seeing any information in the OM.
The Bosch iBooster found in teslas and numerous other cars are electric assist and can infact brake all wheels.
the W213 is a vacuum assist and as such uses the parking brake system to do active braking.
I actually developed an adapter to use the 2nd Gen Tesla model S iBooster on the 87-92 Toyota Supra to facilitate installing a forward facing intake manifold. It works great and with no canbus, it operates as a e-assist brake.
Only reason I know.
