E-Brake and RS-6

I noticed this:


When going 250 km/h+, you can pull the handbrake and it will act like the regular brakes. The only thing different is that the gear disengages, and the revs drop. The front wheels lock if you turn them, as well.

Why?
 
Either the e-brake locks the front wheels on that car irl, or it's a glitch.

Try to ignore the idiotic responses only the "GT5" forum can give.
Yay! We can all agree on something for once! :D GT5 in general forum are filled with trolls and arses. The sub-forums filters them out.
 
The front discs are clamped by gloss black six-piston fixed Brembo monoblock alloy calipers incorporating the "RS" logo, and black single-piston floating calipers, with integrated electro-mechanical parking brake linkage actuating on the rear discs. This electro-mechanical parking brake serves another purpose, it doubles as a full emergency brake whilst the car is in motion, by applying maximum braking effort to all four wheels, resulting in activating the Anti-lock Braking System (ABS).
Neat feature. 👍
New for the C6 RS6 from what I read.
 
Quite interesting! Surely it must be necessary to stop such a Warship from skidding straight unto a wall.
 
Isn't it the same with the Bugatti Veyron? It also locks the front tires instead of the rear tires.

IDK, but the RS6 activates all-four, I can only assume only the front turn red because they have more power sent under full braking?

All the weight shifts towards the front, so I would guess it would be a case of front tire grip-overload!

applying maximum braking effort to all four wheels
I would assume as with most cars the front wheels go first, for obvious safety reasons, though GT doesn't simulate the ability to spin out while fully on the brakes with ABS properly.

Maximum braking effort means full braking force, which doesn't equal 4 wheel grip distribution under braking.
 
I've noticed with some of my AWD cars (those with 50/50 or close to it torque distribution) that the E-brake does exactly this.

Why? Because the drivetrain refuses to spin at differing speeds.
 
Now that is odd.
Here I'd though PD did good in an area. Though I actually don't know how any 4wd reacts to e-brake while driving, I find it hard to believe the transmission can overpower the brakes, especially since most engines can't.

It's not overpowering the brakes. It's distributing the braking force.

For it to not do that, it would have to break.

How would that be possible without ABS?

Now I get it;
without ABS, the braking force (out of 100%) would be 50/50, or 5/5 in GT5. Distributing the brake force to the front without manually using something to adjust it would be impossible without ABS:dunce:

More power being applied to the one with the most braking force.... as if this happened:
1 and 1 (front and rear brakes/normal pressure)
Then it's 1+3 and 1+2 when brakes are fully applied (4 and 3 now)
4 and 3, but now tranny comes into action, forcing equal rotation of both front and rear axles! So it's 4-1 and 3
3 and 3.

Catch my drift?

Again, what?

Locked center diff = no speed difference between the inputs of both front and rear differentials = any force exerted on a given axle is transferred equally to the opposite axle.

Why would you need modulation of the caliper force for that to have any effect? What the bloody hell are you talking about?

Well specifically I mean without ABS, brake distribution is never "distributed" to wheels that aren't locked, etc. It just is what it is, if the front lock and rear still spin, so be it, nothing the car can do would stop it, because the technology isn't there without ABS.

And now you're saying the transmission (power via decelerating engine) would overpower the brakes.
It also sounds like you're saying a car without ABS can somehow sense lock and distribute brake force.

A parking brake typically locks one set of wheels. You said

But the drivetrain cannot distribute braking force, so if the parking brake is locking the wheel, the transmission/drivetrain has no real say, because it's no match for the braking power.
