Help! Need part # for rear brake caliper bleed screw bolt

[georget]

I was trying to swap out my rear caliper bleed screw for speed bleeders and broke off the bleed screw in the bolt! I removed the bolt from the caliper and tried to drill out the remains of the bleeder to extract the bleed screw. Needless to say, I screwed this up and need an entire new bolt! But my problem is I can't find the part # anywhere to order it. I have a Clymer manual and it doesn't show the part. Some versions of the caliper have the bleed screw screwed right into the caliper and others have a bolt with 17mm socket needed to extract it from the caliper. Does anyone know the part # and where I can order this from? The bike is a 2003 R1150R.

Thanks, George

I did the same thing, ordered a speed bleeder that came w/ the big bolt.
Dealer told me they could only order the whole caliper
Speedbleeder came from somewhere in midwest.

So I got lucky... I have a friend who is a mechanical engineer and a great machinist with lots of tools. I took the bolt to him and had him take a look. I really didn't screw it up as badly as I thought! The remains of the old bleeder screw were still in it. We drilled it out but did so using his metal lathe! What a nice piece of equipment. He inserted the bolt into the side that spins and put the drill into the other side that moves back and forth but is stationary. VERY slowly he inserted the drill and it reamed out the hole and removed the remains of the bleeder. He then used a 6mm tap to "fix" the threads that were damaged in the process. We then put some oil on the new speed bleeder and fitted it into the repaired bolt! He took a compressor and made sure that the bleeder worked properly (it passes brake fluid only in one direction because of the check valve in it). All is now okay! Believe it or not, the hardest part of this job was to find a 6mm tap! After going to Lowes, Home Depot, auto parts stores, we wound up at Sears who had exactly what we needed with a 6mm tap and 6mm drill. It took us almost 2 hours to find the tap and about 2 minutes to use it! Such is life. Bike will be back on the road later today.

I learned a lesson to be VERY gentle with frozen bolts. Use penetrating oil first and do not force. Let the oil work over time. My friend restores old cars and learned this lesson a long time ago. Of course, it had to happen to me for me to understand that brute force is not the answer (to most problems). As they say, experience is the best teacher!
