Carrying on from my previous post. 2006 R1200GS

I have removed servo and linked out front and rear brake lines, all OK on this front. I now need to remove the electronics part of the servo unit so I can plug this back in to retain speedo and other functions as recommended by many on this forum. But how do you remove those damn security screws on the servo unit? They appear to be some special security fixing like a torx screw but not.

Help please? Drill them out?

Thanks
Mark
 
I just replied to your other post in the other thread. Hammer the six-pointed torx bit into the top of the screw. The screw is fairly soft so it will go in easily. They're not too tight, so it will come off without ringing the heads.
 
Thanks for the advice. I made a slot in the screw heads with a hacksaw (just enough room) and got the screws out with a flat bladed screwdriver. The electronics part is all sealed back up (used an old number plate) and installed. I just need to figure out how to get the instrument cluster apart to blank off the ABS warning LED.

Not much figuring out required. Mind you the four security bolts didn't need much figuring out but had you stumped for a while. :D

Remove the three circlips that hold the cluster in place. Unplug the electrical connector. Undo the 5 screws holding the back cover of the instrument cluster in place.
Mind you don't lose the trip meter button prong. when pulling the back off.

Replacement is the reverse procedure.
 
Steptoe, apologies I've been away on holiday. Thanks for tips re the instrument cluster. All done and sorted now. I blanked the red 'Brake failure' warning with a couple of layers of black gaffer tape, the second red warning triangle i sorted by covering the discrete red LEDS and leaving the other yellow amber ones so they can warn of other things.

Did a test ride to see if the non servo ABS brakes were OK, they're more progressive (don't have the initial bite of before) but with a little more lever pressure she pulls up good and quick.

Off to Spain and France in September the day after my daughters wedding! I may need a bit of bike riding therapy by then.

Thanks to all for your help on this.

I'll try and post up a description of the work involved when I get a moment. Unfortunately I didn't take any photos at the time:blast. I'll see what I can pull together. It's really not that difficult if you're used to practical/DIY mechanics, just a bit of head scratching at times. If you were to do it a second time it would be a dodle. Motorworks supply a kit of parts that you need to do the servosectomy at about £80.

Cheers Mark.......just a question...is it the pump that gives up or the bushes in the electric motor..?? as I watched 2 video's that show the bushes sticking in position and is a easy fix, but a faff to get to them.....

You're confusing the early servo/abs brakes with the later abs brakes. Completely different systems.

Cheers....

Could u tell me when bmw stopped using servo assisted on the r1200 range, I'm looking at a 2010 r1200r would this bike be affected by the dreaded abs problems...???

A 2010 won't suffer servo problems but the ABS modular motor will eventually go wrong. At least it's usually a cheap fix.

Cheers guys.....are the servo assisted brakes really that unreliable as there's plenty of bikes up for sale and not being gullible enough to buy any of these.....but the owners all state that their bikes are reliable.....I'm getting a sore head trying to figure out whether or not to venture into this route....

My Servo was still working alright at 35k miles when I bought the Bike,even though the ABS had failed.
I whipped it off anyway, just in case it caught me out further down the line.
With Braided Lines and decent Discs and Pads, the Brakes work well enough without it anyway and it's not a huge Job to remove it.

Mine's still going strong at 68,000 miles :thumb2
 
It must be possible to overhaul the servo. Has to be worth some surfing to find out.
Take a look on advrider
