I stay away from hills! no actually it works when stopped, but I tried to get around a corner quicker at an autoX, so I pulled it, and it didn't engage at all. Then someone told me it wont work while driving, and an AWD car. I was mis-informed. This is good info to know! thanks for posing the question.

 

Wow, this is good info to know... I had no idea a mechanism was in place to prevent this kind of damage to the centre diff in an '03.

 

Most cars just have a simple cable that actuates the rear breaks when the emergency break is engaged.

It gets more complicated when you have 4 disk breaks. And that is part of the reason you guys paid 30k for your cars and I paid 12k.

 

Yeah Evo has a simple cable also fool. The ACD picks up that the wheels are lock from the ABS sensor and then decouples the ACD. Why in the heck are you using the parking break on an AWD car??? Just turn the wheel and hit the gas, insstint donuts. I think I have a video somehwere of me doing them in a my old Eclipse. Did some the other night in the Evo also.

 

you/we don't have the ACD center diff.

With the ACD center diff if you pull the handbrake just enough to turn the e-brake light on, then that signals the center diff ECU to put all the power to the rear axle


If I have any regrets on buying my EVO, it's that I should have waited for the '05

 

The E-brake on the Evo is a "Drum-in-Hat" design, meaning it does not engage the disk BRAKES. There is a small, drum style brake mechanism inside the rear brake rotor that is only actuated by the E-brake lever. It is all mechanical with cables, no hydrolics.

Not all cars with disk brakes in the rear have this feature, but it has the advantage of allowing you to park the car after a hard run and use the E-brake without damaging/warping your rotors by engaging the hot caliper to park.

 

Simply to do a handbrake turn. I wasn't trying to do doughnuts. Might do that tonight

 

Not exactly, it disengages or opens the center diff, so you will get wheel spin more easily, but it won't overwork the E-brake or the center diff if you try to accelerate while using the E-brake.

Once again, the power is ALWAYS split evenly front to rear on the Evo, there is no way to change this without removing drive shafts.

 

I do not think you are technically correct. As was stated earlier, when you pull the handbrake, the center diff ECU completely disengages the limited slip function. That way, when you pull the handbrake, it is easy to lock the rear wheels, thereby inducing oversteer. If the ACD engaged harder (which it would if not programmed to "let go" when you pull the handbrake), it would be very difficult to lock the rear wheels, not to mention put more wear on the ACD clutch plates.

 

Not exactly again. It opens the diff and the ebrake engages the brakes on the rear only. While there is still power going to the rear since it is now has the brakes engaged and the center diff is now essentially an open diff most of the power transfers to the front wheels that are relatively free compared to the rear ones that have the brakes dragging. Just like in a car with an open diff stuck in the sand. The wheel that has grip sits still and the one that has less resistance spins.

 

Exactly!

How does that differ from what I said?

 

Because the power is not ALWAYS split evenly if it is sending more power to the front when the E-brake is engaged. Just like it varies with the different ACD modes. On Evo's without ACD it is always 50/50 but, ACD has a bias.

 

Ah gotcha, my last sentence was a little out of place. I was addressing that there is a misconception that the center diff can send different amounts of power to the front and rear, which it does not on the Evo. No matter what mode the ACD is in, distribution is 50/50. The modes adjust how strong the diffs lock...more open in Tarmac mode, locking sooner in Gravel mode, and even sooner in Snow mode.
