servo ABS brakes

Looking at this thread with interest and disbelief
While I share the disappointment of the owners who have had problems with their brakes, neither of the two systems is new, ABS has been common place in one form or the other from the late seventies, servo assistance has been around for ever.
Why is there such an issue? if indeed there are failures then it should be flagged up with whatever department of transport to put pressure on the manufactures to put it right. Not fit for purpose !
Or is it the dealers who are making wrong diagnosis, some threads from memory report that the servo has been changed 3 times ? once maybe, three times ?

Well I have had my twopenny worth, i'm of to take the injection system off and replace it with carbs, put tubes in the tyres, rip of the hydraulics brake lines and replace with cables,and never get on an aeroplane again

Well I am impressed that some people can brake as effectively as a servo assisted abs brakes system, and presumably if it locked up you can release and re-apply your bakes as quick as a computer can. Now thats impressive!

Some of aren't that good and rely on technology and boy does it help. Also it's safely taught me just how hard you can apply brakes.

So far the system has impressed me no end. I'd be relauctant to own another bike without it.

You must ride really quickly on the road to need to brake hard enough to use the ABS constantly, I am in awe!
Or perhaps it's an inability to assess the conditions correctly?

No, it kicks in at as little as 10mph apparently. I filter through London traffic, as much as I try to command all people in cars or pedestrians, to do my will, some actually make unexpected moves!! Shock Horror!!!

I use to think it was just me that was unlucky, but apparently there are lots of accidents involving bikers!

Let's just hope they get the airbags issue sorted quickly so we can all have the option of even better protection. Better still,let's make the fitting of all 'safety' items a legal requirement.
On a more serious note,don't you ever question the viability of using a bike in some of England's traffic conditions?

No, really: Servo brakes are shit. Don't buy BMW Motorbikes with these brakes. For your enlighting I like to recall the German News beeing on the topic in July 2005:

Nothing to see here, just a couple of links to German sites (ok if you can read German of course) provided by our man on a mission, the man who has redefined the meaning of "obsession", the one and only Nemizis!!!

ABS isn't the problem -

the servo system on the Bikes is electrical, the servo systems that you refer to " as being around for years" is vacuum operated -

Lots of BMW car as well as two generations of Range Rovers (I'm sure there are more but these i'm sure of) have had electrical servo systems for their brakes. The technology has been around for at least twenty years and i don't see any Range Rover owners complaining about their brakes.

The electrically assisted brakes on my 1150GSA are simply amazing. Does anybody know if there have been problems with such brakes in 1150s or is it just an issue in the 1200s. It might just be bad design of the electrical system on the new bike...

The K1200rs has had a lot of problems, i know of one owner who gave his bike back, after several brake failures and a couple of new servo pumps.

He's now got a 1150 ADV, ( non servo )

So whats that got to do with failing BMW bike brakes ???

because range rover brakes don't fail ( everything else does, especially the electric suspension ), that means, therefore, that BMW bikes shouldn't fail ?

Lol, teh new Gold wing thing has an airbag!

I got T-boned the other day, and whilst he was wrong for jumping the red light, better observations by me might have prevented it? Sometimes I do wonder about the wisdom of using a bike for commuting, especially after seeing a spate of incidents involving bikes. But I probably wouldn't have a bike if I didnt use one for commuting as I rarely use it outside of this.

Occasionally my Wife will start making comments about the dangers of bike riding. But I see it like this, if I died on the bike at least I died doing something I enjoyed. If I died in a train crash I would have died doing a journey I hate and God knows I hated commuting by train!

So, I happily accept the risks and just carry on enjoying riding my bike to work and back.

Electrical brake servo's aint that new either, my point is as a safety critical item the system should be more robust than some of the threads claim.
If indeed there correct, either BMW have not tested it properly (I am pretty sure they have) or their ‘bean counters’ have tried to squeeze too much cost out of the system between the proto and launch and now faults are beginning to show up.
I am sure that the problems would get more attention if they were on the car side of the bussines.

Electrical brake servo's aint that new either, :

i know - years ago used to help out a mate who worked on refuse trucks, they have electrical magnet brakes that operate on the prop shafts ( maybe BMW's next idea for the bikes - electrical drive shaft brakes !! )

 

[Alex]

Still though, electric servo brakes are used in late 1150s without problems. Could the problems be in the canbas electrics of all 1200 generation bikes and not the brake system??
If it is so, is it worth ditching the servo system altogether, or should there just be a redesign of the new electrics system in the 1200s

Not true - they have problems as well .

 

[Alex]

How do you know?? I haven't read about any problems on 1150s in any of the forums i visit and i haven't had any problems with mine...
