I now need to find out what tool/part I need to do my front brake fluid flush?
I felt pretty silly after finally finding the rear brake reservoir, thank you, flushed out now it's time to do the fronts. I did look at it by pulling that set screw plug out of there on one of the calipers, obvious that I need a tool/part to do this....

Look at the "Clutch bleeding"-thread dicussed few days ago. Exactly same tool / bleeding problemacy there and solution(s) presented.

That set screw is usually called a grub screw in this site...must be something german,so if you do a search use that name.
Now C-A-D mentions to look at the post from a couple days ago and if you find it, that is your solution. If you don't find it then get either a speed bleeder or a regular bleeder, thread it into that hole and bleed away. If you look at the bottom of the hole you will see a ball bearing, that needs to be depressed to let the fluid out, hence the replacement bleeder. You can leave it in after you are done for future work, and don't forget to do both sides.

Need to know what year your's is or whether you have "brembo" or "BMW" on your front calipers. It makes a BIG difference in how you flush. Not hard just different.

My bike is a 2000 BMW 1200LT - the front calipers have a grub (set) screw in them.
"brembo"??? never heard that term before jzeiler

"speed bleeder" I actually have 2 of these (some wheres) johnbaker15 and this thought actually came to me at the time I was eyeballing this as you were describing it and I saw this, but, the speed bleeder option went out of mind as quickly as it came in as the ones that I have went to my old Chevy Suburban. HAH....I'm going to look for them and compare them with the grub/set screw to see about thread count and diameter.

If I'm on the right track then all is good although I am still puzzled with "BREMBO".
I am a confident wrench spinner and machinist on Harley Davidson's, gave them up for something a little bit different....hhhmmmm brembo???

thanx guys

I just looked up Brembo, excellent question and has peeked my curiosity as these types of calipers are specific to ABS systems, which I do have...thanx for the lead jzeiler

brembo calipers are what I have, just looked

2000 1200LT - what's different? I do have brembo calipers front and back, I did the back end pads and flush already, didn't seem to be a "biggie". The fronts had me a bit stymied with the grub screw only and no bleeder. I did eyeball it and noticed how the workings were as noted by johnbaker15...I don't understand the "German" way of thinking here as why not just use a bleeder like the rear caliper.

The difference is the 2000 does not have Servo assist ABS, and thus flushing the brake system is much simpler.

That unit that has the grub screw is the filler adapter. That is where the factory fills the front brakes. They just left it on when they were done. Stopped doing it in the later years. A short 10mm bleeder nipple will fit, some time you have to file the point a little to get it to thread in. You can use a heat gun to soften the Lottie and remove it altogether. Just replace it with a 10 mm bleed nipple.

thank you, now I am curious about the servo assist abs, just a "want" to know thing than a "need to know...when you have time....

I was looking at bleeder screws, are they 10mm X 1.0 thread or 10mm X 1.5 thread??? This is certainly a need to know thing...
