Has anyone experienced the Brake Assist?
Just wondering, was thinking about trying some panic stop but haven't gotten around to try yet.
When the brake assist engages, does the brake pedal stay down for a little longer?

The pedal pulls down and away from your foot, which is a little un-nerving the first time you feel it. The first time I needed it, by reaction, I pressed down harder. ABS took over from there and the pedal pulsed under my foot. The good news is....the brakes didn't lock and I didn't wrinkle my baby....

I don't think it requires a panic stop. I think I can feel a more than linear reaction when stopping. Next time I can steal the car from the wife I will try a panic stop on a smooth road to see what happens. By the way, on an Air Force E-4B (Boeing 747) test flight, the pilot engaged the brake assist on a high speed taxi. It was a toggle switch if I can remember and stopped the 700,000 lb plane pretty quick. That was 16 years ago and I can't believe it has taken this long to get on autos

I have experienced it with my ML. I was only going about 50, cars in front of me were stopping, so I pressed the brake pedal, but certainly not to the floor and all of a sudden my ML just slowed down incredibly fast, I wondered what happened because I wasn't braking that hard. I realized the brake assist had taken over. It's hard to describe the feeling. The only way to know it had happened was how fast it braked. I think it's fantastic. I think it will do as it is suppsed to, i.e., when it thinks you're doing hard braking but not flooring the pedal it presses the brakes harder for you.

I guess I am a fast brake pedal pusher. When I first got my C, I was activating brake assist while stopping at stoplights. It does catch you by surprise. My main concern was someone rearending me, it stops you FAST! My braking technique has adjusted and brake assist hasn't reared its ugly head in quite some time.

anyway, first time I triggered BAS on the C240 all my books got shoved from the passenger seat into the glove compartment. I totally wasnt expecting it. just some lady pulled in front of me and I needed to slow down, but in no way did I want to stop.

BAS
I have had it activate once while driving. I can’t reproduce it just by hitting the brakes. I was cut off by another driver. I think that it reads your retina and knows you are really panicked. Any way it worked like nothing I had experienced before. It was really violent. It threw my wife on to the floor and under the dash. She should have had on the seat belt. It was kind of funny afterwards. But it did prevent me from running into that guy.

It caught me by surprise and scared me. Lol. It is very crazy and stops you so fast its unbelievable. Some one cut me off and I started to push down the petal, except all of the sudden it went in by itself and flung my body forward grabbing really hard on the brakes. I didnt know about brake assist so you can imagine my surprise. Its nice to know its there for emergencies.

I used to wear my seat belt "sometimes" until I had a near miss on the beltway in Virginia in 1982. I was nearly side-swiped by a female who just got her license and was rushing to the airport. I saw her out of the corner of my eye and swerved only to begin fishtailing (no ESP back then.) I did a 180 and ended up next to the guard rail with lots of headlights coming toward me. Luckily neither me or my car were hurt. Since that day, I've never driven without my seat belt snugly fastened.

I'm with BigBadDad - experiment, then adjust accordingly. While cruising through a tiny town, looking everywhere but forward, a pickup pulled out in front - I swerved, had no intention of stopping, but the car determined otherwise. And you do stop quickly! Don't care to repeat that experience, although it's nice to know it's there if you really need it.

This subject reminds me of a tragic story...
I used to work the news desk at a TV station. Got called out one night to the scene of a fatal one-car accident. A woman had plowed her mid-70's land barge headlong into a very stout tree. The Police figured the impact did NOT kill her. However, the umbrella she kept stored on the package shelf above the rear seat DID decapitate her. Not a pretty sight...
Somehow, Brake Assist reminds me of this event. The rear seat headrests on our Sedans and Coupes would hamper the forward motion of large items on the package shelf (or Coupe hatch cover), but I imagine the violent nature of Brake Assist engagement would launch anything else forward with great force.
Hoping you guys don't store anything in these areas... It's not worth the chance.

The G-Forces of rapid braking are not that high, I'm guessing under 3. Not enough to launch something hard enough to decapitate you (well, except for that machete you keep in the back of your car)...
It's the G-Forces of a sudden stop/crash that will launch items with such force. Now we are talking G-Forces in the 10-30-60 range... or worst...

with the coupe's hatch back, luckily can't really put anything on the cover.
Even when I had my old sedan, I only had a box of kleenx there.

. Some people might not be as well informed as you are.
. Remember, one guy asked if his car even had this...

i have felt the brake assist kick in a bunch of times. Usually when i brake lightly for a long time after a few seconds the brake assist will kick in and slow the car down faster than i want it to. I like to give myself time to brake, and come to think of it it usually kicks in when i'm going down a hill. it feels funnny because the brake pedal will all of the sudden get really soft and move forward.
