Servo brakes....... yet again 4/9/05

I thought you had him on ignore.

Ignore him if you like, but I don't see why this sort of thread always has to descend into personal insults.

The suggestion that their precious BMWs might not be the best bikes ever seems to get some people a bit riled up. Are you going to suggest Steptoe needs medical help too, seeing as he agrees that servo brakes can fail in the manner described?

Here, here...

It's understandable that people's responces to Dr ABS become personal.
You're dealing with a person who doesn't own the bike he is so concerned about,will not reveal his identity and will only respond to questions if the answer involves a negative about BMW.
If you met him in the street,how long would it be before you walked away muttering ' ?

The big difference between Steptoe and Dr ABS brake/Nemizis is that Steptoe doesn't just contribute to this forum on the issue of servo ABS brakes. You will see his contributions on a wide range of subjects and issues. Steptoe brings much to UKGSer. Nemizis does not. All we get from Nemizis is posts about his obsession with BMW/servo ABS. Nothing else. Most contains links to articles in german which are of no use to the majority of the members of UKGSer.

Bob. I do understand your point and sympathise with it to a degree. I often ignore his posts but occasionaly have a dip into them to see what his latest views/information is.
In the back of my mind I can't help but feel a certain concern that all may not be as it should with servo brakes. I have had mine fail through a self inflicted action (not a BWM failure) and I was not impressed with residual braking.

At least he has planted the thought with us that it's possibly something we should keep an eye on.

If at the end of the day BWM are found at fault it won't come as a shock to us.

In the meantime we can view or ignore his posts/threads as we decide.

I reckon you old boys should try disconnecting your car servos and try to stop them from 30 mph. It might shock you.

Actually it doesn't since car servos have a 'pressure reservoir' which enables you to brake 4 or more times to brake 'normal' like the servos are okay, then you get the sensation of having 'no brakes'.

BMW power brakes are different. They have no 'pressure reservoir' and you get immediately the sensation of having 'no brakes' at all.

My question therefor is: Why do BMW powerbrakes on motorbikes do not have a 'pressure reservoir' as cars do have?

After reading this er's last question I can understand why he gets personal insults thrown at him! And he dared to doubt Hitler's intelligence! off and die Dr Head-up-my-own-ing arsehole.
If you haven't got a sensible question to ask,don't bother asking it. It is amazing to what depths you will drop to try and get another negative line of thought going.
off and die!

Sorry,but it had to be said.

I have done that, and you can stop fine. Obviously you have to pull really hard on the lever.

harder & longer lever travel


According to German motorbike press sources the new system 'might' be available in spring (march) 2006 on BMW R1200S. AFAIK at the same time they present the BMW R1200GS Adv.

Brake fail warning on R1200 with ABS

Has anyone else had the problem where the red flashing triangle and the brake fail warning don't clear as you drive away? My bike has covered just coming up for 1100 miles now and the times this happens seems to be increasing. The problem is cured each time by switching the engine off, turning the ignition back on, letting it go through its checks and then restarting. Sometimes takes two restarts though to clear. Yesterday drove on for a bit to see if the warning cleared and the speedo didn't work either! Brakes actually seemed to work as normal though even though the warning was on.

Oops I misread the message I replied to above. Car servos, not bike! Ignore me

PS robp - when the fault happens, is the "brake failure" fliashing fast or slowly? If it's slowly, that indicates an ABS problem (I think). Check the ABS sensor on the front wheel, and check the cable to it is routed correctly and undamaged.

 

[robp]

Mouse, I think it is flashing quickly - will have a look next time it happens. I reckon it must be something to do with the general electronics though as, as I said, the speedo wasn't working last time it happened.

Turns out that the fault is a brake modulator. Bike is in the shop with one on order. Dealer reckons this is the third one of these that they have replaced recently.
