    Photo Bucket sucks so now it's attachment time! Sorry about the HUGE photos.

    I started at the rear.

    REAR and PUMP

    remove lines from the pump and hook the caliper line directly to the pump.

    remove your seat and fuel tank and the large plug on the ABS ECU

    pull the steel lines out of the way and remove the pump. you will need to bend the lines for the rear circuit to get them out.

    FRONT:

    locate the junction blocks and remove the lines from these blocks. Join the line from the front lever directly to the caliper using the small junction block.

    bleed the calipers just like you would any conventional system. place a coin over the pilot hole to keep the fluid from squirting out.

    IMG_4899.JPG MOUNTING THE ABS ECU

    you will need to remove the ABS ECU from the pump body. I used a cutoff wheel to make slots in the heads of the 4 mounting screws.
    IMG_4896.JPG

    remove the ECU leaving the ribbons on the pump. the other connections go with the ECU
    IMG_4898.JPG

    make a cardboard template. I used 1/8 aluminum plate for the final product. that's what I had laying around. any thin plate will work.

    transfer your work to the plate. I used a sabre saw to cut the plate
    IMG_4902.JPG

    bend the tabs so the ECU sides will be covered - if you use a thinner plate you will not need to use a torch.
    IMG_4904.JPG

    remove the original pump mount and bend to accept the new plate you just made
    IMG_4905.JPG

    lay a bead of your favorite silicone around the perimeter of the ECU and bolt the ECU to the mount. install the unit onto the bike

    remove the BLUE ABS relay. this will get rid of the flashing light.

    IMG_4908.JPG

    remove the bulb for the triangle light. it pulls out of the socket from the rear. you do not need to take the dash apart.
    IMG_4909.JPG


    you now need to figure out if you want to keep this or not. I kept mine for around 4 months and then chucked it into the garbage. lol

    ENJOY!!!!

    go for a test ride and enjoy your BMW WITHOUT the ABS Worries!!!

    A little over 3 hours, start to finish

    I hope this helps out the one person looking to do this!

    Cheers, Thirsty

    BTW, the brakes have better feel without the servo unit. :)

    This is still one of the best things I have done to this bike. AND I liked the servos . I lived with them for 9 years.
