Brake options

[ChrisH Kerry]

I put a post in the 'You know you want one' but maybe here is a better place... what I want to know are what are the available brake options for the 1150GS and how to recognise them as I'm looking for an 1150. As I understand it there are ABS and non ABS versions, some bikes have servo assisted brakes and there is EVO (?) Are all late 1150s servo assisted? If so what year did they bring that in? Can you turn off the ABS without turning the engine off? As in - if you're heading off down a green lane or track? I think I'm probably after one without either servo or ABS but not sure.

Early bike use the same callipers as the K 1100 series a very square looking calliper with one central mounting pin for the pads

Discs look something like this with a mounting ring to the wheel centre and bobbins that let the brake rotor "float"

Evo Discs look like this

Look at the left side front brake disc ?

Is there a Toothed or grooved ring slightly smaller inside the brake disc then it had ABS fitted when it left the factory

2 Blinking together lamps when you switch on the ignition would be ABS II

Then Integral ABS or Servo assisted would be from late 2003 on and has one steady lamp and a quick blinking lamp and when you pull or press the brake lever (once it has checked itself and gone to a single blinking lamp) you will hear an annoying whirr until you release the brake

Go for ABS II and make sure alll the fluid changes ahve been done and you'll be fine
Servo ABS is a PITA and is much to finnicky to be a sensible option plus with ABS II I can send you the diagram to rewire to cure a fault when the battery is low*** and fit a switch to Kill ABS when on the move (You need to stop the ABS before you go off road with the BM switch)

WARNING IF you think you have an ABS II bike and the lamps flash alternately once you turn on the Key then there is a stored fault code warning However you can ride the bike safely but the brakes will be ordinary non ABS
If you have alternately flashing warning lamps*** after you have pressed the starter button then it needs a good charge or the battery replaced but this is a non stored code
Basically if you have warning lamps that flash at all once you have ridden away there's a fault and the ABS is disabled!

If the Servo ABS disables itself you WILL know!!!! NO SERVO means you'll need muscles like Swarzeneger to stop the sumbitch! BUt at least they flash the light for you!

BUt at least they flash the light for you!

Not for me they didn't

 

[DrFarkoff]

Not for me they didn't

Oh dear! they're supposed to!

One apologises, but, one must enquire, Was Sir able to significantly reduce the forward velocity of Sir's Iron steed with enough reactions to avoid an accident except perhaps in Sir's undergarments?

Was thinking the same thing about Servo ABS... like the idea of being able to turn off ABS on the move, so how do I know when ABS II is fitted?

Is this one a non ABS, non servo model? Can you tell?

thanks for the info

Servo

Triangle in lower warning lamp stays on while upper flashes quickly while doing brake checks then goes out and upper flashes synchronously

ABS II has ABS in both lamps

 

[ChrisH Kerry]

Ah, now I understand!! Strangely though I don't see the ring on the front left wheel or the sensor on the rear?

 

[DrFarkoff]

Ah ha all the dashboards are the same

It's Not an ABS bike

Even better as far as servo ones concerned

are the sparklplg covers long from front to back of the centre of the rocker cover or sort of tadpole shaped?

 

[Steptoe]

You have a choice of non ABS or ABS up to 2002/03.

From 2002/03you have non ABS or ABS, but the ABS has servo assistance.

Thats all you need to know.

You can turn the ABS on and off but not on the move.

 

[ChrisH Kerry]

Right, so this one (2003) is non ABS and non servo, just like ordinary brakes then? Sparkplug covers go from front to back

 

[Steptoe]

Right, so this one (2003) is non ABS and non servo,

If it's non servo it'll also be non ABS, you can't have servo only without ABS.

Once again, only three types of bikes .

Pre 2002/3 ABS

Post 2002/3 Servo (with ABS)

All non ABS bikes brakes are basically the same , except for front calipers which may have brembo or BMW stamped on them.

The picture in your post above is a single spark (they have the full length of the valve cover spark plug cover) - twin spark has "twin spark" written on the spark plug cover and it's only about half the length of the valve cover .

Brakes packed up after I left my house. I'm the second house in from a junction, so I was only doing about 5 miles an hour. Stopping was a "strange" experience to say the least.

I stopped, pondered, thought I must have ridden off without letting the warning lamps go through their normal sequence. Watched the one lamp go out, pulled away, second lamp goes off. Applied brakes, no brakes, stopped, warning lamp or lamps then came on. it was nearly 5 years ago, I can't remember the exact details.

My pants lived to fight another day.

 

[King Rat]

Total confusious now...so what would 2005 1150GSA be fitted with? ABSII by the sound of things.

I have 03 GSA and it has the servo and ABS, but I have never had the brakes on hard enough to find out if the ABS works.

What do you want brakes for anyway? They only slow you down.

Not if you got the special sort mentioned above
