Bleeding the Integral ABS

November 29, 2008

A very detailed tutorial about bleeding the servo integral ABS brakes. It should work on all R 1150 and R 1200 bikes.

What happens:

– brake overheats during extensive heavy braking (like going fast on twisties or on the race track)

– brake levers feel spongy

– brake loses power

When happens:

– brake fluid too old (recomended change every 1 year, to be on the safe side)

– riding for prolonged periods of time in rain or wet environement, like in UK (brake fluid absorbs 2% moisture per year through hoses/brake reservoir; when it reaches 8%, it will overheat)

– problems with old o-rings or brake lines

R 1100/1150 ABS Reset

November 15, 2008

Maybe your ABS doesn’t start in the morning. Or maybe you’ve just taken a spill and the least you want now, with all the adrenalin running through the vains, is not to trust yourself in the braking of your motorbike. But it’s a quick and easy way to restore your confidence. Use this to troubleshoot rather than find the solution as the ABS not working (and flashing it’s annoying lights) may come from other problems, like an old battery or different-from-the-book ABS sensor gap.

What happens:

– dashboard flashes alternatively the ABS lights when running

– wheel locks under heavy braking (try the back wheel so you don’t crash)

When happens:

– when taking a spill
