How does it take-up slack (Pad & Disc wear).

hello.
please send me full’information in EWB.
thank’s.

Nola, I don’t think EWB is a good idea.

Throttle by wire is fine and good, that’s because I know I can still stop the car even if the throttle goes whack. But break is last resort and it definately should be the conventional stuff or some other reliable and non-electronic stuff.

I’m an Electronic Engineering student, and I don’t trst electronics to save my life. To me right, Electronics should be there to help improve the underlying system, not replace the system itself.

Final words: Braking by wire is very very very dangerous and I strongly (X1000) discourage any auto manufacturer from pursuing this.

“Err bang, change the brake pad pls, how much ar? ”

“RM40 lar i give you.”

“ok.”

“eh, not right lar bro… your electric motor in your Siemens EWB brake caliper rosak lar”

“How much??”

“Around 800 per motor….you have 2.”

“…………………….”

By 2010, the best car will use EWB, but the hopelessly P1 stone age Iswara still use drum break!

just a small point:
“Even brake by wire has been introduced as a concept technology”

It has been used on the Mercedes E-class, CLS-class, and SLR since 2002. In fact, it has already been discontinued and replaced by the next generation of brakes in the facelifted E-class (2006) although it continues in the others. So it’s not just a concept technology.

very innovative!

but still lack confident on “electronics items” , especially this is a life saving items!

especially the motor life-span, reliability and robustness ?

I’ll pick electronics over mechanical any day. If everyone is worried that electronics may malfunction, what makes them think hydraulic mechanical brakes wont? It’s evolution, live with it!

so now bad people will be able to mess with the electronics and make the brakes rendering useless haha just a thought

This is nice brake. If electric motor malfunction, then got story about the crash. But electric thing need to maintain every time, very easy get broke. Long lasting? Some people still don’t know how to maintain their car. =/

This is a good technology, if people is speeding like crazy, it gives people more allowance to stop in time to avoid a disaster. A total revolutionary in car technology.

Very good idea, although I am abit worried about it being fully electronic.

The problem with technology is that you can’t advance it without making it more complicated, two power supplies with another back up battery? Come on some people already have trouble maintaining one, wats more two that powers the brakes.

Can’t imagine what future car will looks like when all those mechanicals stuff taken over by electronics.Car will be much lighter,engine compartment will be smaller and we will get more space in the passenger compartment.

these kinda high tech brakes fitted in a proton?
haha…
i, as the CEO of Proton, announce that the prices of all the Proton range this year will be up by 10k…
that is because we will be fitting all the models with an EWB as standard and
this is to ensure the safety and the well-being of our dear customers driving our not soo strong milo-tin cars…
we just want our customers to know that we really care and value our customers just like the way they value our masterpieces(milo-tins)
yours truly,
ceo of proton

I suppose brake feel and modulation goes out the window with this. Binary brakes to the max.

another brilliant design from market leader.
but what will be the price to have one???
hopefully we can see it fixed into our proton one day…
god bless us long life..

I have a phobia with more and more electronics taking over the good old traditional mechanical stuff. But for the benefit of safety and timing, electronics would eventually be standard. I’m sure that Siemens would take the necessary precaution if its primary systems failed.

what if the electronics doesnt work?..if that happens the brake wont let you stop right?if the brakes still works without the electronics ,great innovation.

Don’t know if I’d be too confident driving something like this.

Modulation could be odd.

If I can draw any parallels with BMW’s active steering and throttle by wire, they just feel artificial and lacks “feel”.

Not all technologies work well first time out. Like run flat tyres, which rode horribly.

Having my brakes not work perfect the first time out is disconcerting to say the least.

This product is still a PROTOTYPE.

I think the concept is good, but size and reliability does matter to OEM.
If you compare the size with Hydraulic type its almost double and bigger in every dimensions. Before OEM apply it on Mass-pro Siemens should come out a better solution of its size and reliability of it, therefore they need time to study it…..until 2010.

simply is brilliant design , self-energising..good,,
to a point can it produce a brake feel and modulation? ….i guess,,,

as an extention of electric power steering,
i bet theres gonna be a steering without rod one day, just like aircraft, and complete with steering weight feed back,maybe

electrical connection should be in gold to prevent corrosive causing open circuit perhaps, ($$$)

…..scarry..im nor ready yet, but its aerospace tech, higher safety standard,
sevice periodically like an aircraft,

really not ready for this,
anyway no one can stop technology evolves,
