BMW R1200RT/R1250RT Forum

Hi. Sorry to be a newbie starting with a question.


Recently bought a 2005 R1200RT after having a break away from bikes for a couple of years. I believe the ABS has been bypassed, I know there is paperwork for it in the folder I got with the bike.


Problem started yesterday. Short run out and noticed what sounds like the brake servo's are running on after releasing the lever/foot brake. Checked levels all ok. Checked and could hear switches operating as should be. Anything else I should check? I would have thought these would have been bypassed along with ABS?


Thanks

This video shows the servo and ABS being removed from a 2005 RT, BMW R1200RT IABS3 Servectomy - Whizzy brakes removal - YouTube

Might be worth viewing and comparing with what has been done on your bike.

Hi David. Thanks for the reply. I have a funny feeling that the ABS has not been removed, despite what i was told, but may have been repaired at some stage. My reasoning being I don't think the ABS can be removed without also removing the servos. The noise i am getting sounds live the servo 'running on' after brakes have been released


Looks like I may have to do it myself  :sueno:

To bypass the ABS unit, the ABS doesn't have to be totally removed. The basics are just a couple of brake light switches, a "U" union, and a longer rear brake line. also a bit of wiring. Why convert to no ABS if the servo sounds to be working?. Have a look on nippy norman site who sells the bypass bits. They also have diagrams of how to fit. Have a look at the front where the pipes join to see if there is a "U" cooper union there. if so it's been bypassed.

Hi. Problem was the servos sound like they ran on after brakes were released. Unit is out now, just waiting for kit to arrive
