This one should be easy! I'm a new owner and trying to figure everything out ...

I bled the left front with the mityvac tool. How do I know if I've done it right? The brake lever seems to be firm.

Also, I went to bleed the right side (same side as reservoir) and there is no nipple. I assume I have to purchase one? If this is the case. How do I remove that bolt without all the fluid seeping out. If it seeps out won't I have trouble bleeding?

Thanks!!

On my 1100RT I replaced all bleed screws with SpeedBleeders, including on the right front caliper. That screw dohicky you mentioned on the right front caliper is a BMW thing for use with their equipment, but is not needed. I don't use anything fancy for bleeding the system either, just the SpeedBleeders and 8" of clear tube. I like the clear tube so I can see the bubbles. Open the screw, slowly pump the brake lever to push out any air, while adding fluid to the resevior, close the screw, done. Easy.

I have never bled the ABS unit. I don't think it is really neccessary, but someone may come along and tell us how to do that (I don't know).

FYI... If you buy SpeedBleeders, beware the screw for the rear caliper is very small and it is easy to over torque it and break it while screwing it into the bolt that screws into the top of the caliper. (1150RTs don't have this additional bolt). If you do that do not fret. SpeedBleeder has a replacement for that, and will extract and replace the one you broke free. They are very good people to deal with IMHO.

As long as you have the reservoir reasonably full you will be able to withdraw the grub screw and install a bleeder without draining enough to allow air in the top. Fluid dripping out the bottom while you do this won't admit much air either - and if it does allow one little bubble (inside the dry bleeder) that bubble is located where it will be expelled as soon as you start to bleed that side.

Your bigger worry is to arrange and have handy sufficient rags to contain and clean up the little bit of fluid that rins out while you are fumbling to get the bleeder in and tight. Don't hurry. A little extra fluid drained out is a whole lot better than a crossthreaded or stripped caliper thread.

I have done the replacement of the factory-installed thingy on a buddy's bike with a bleeder screw. No big deal.
HOWEVER - BE AWARE!!!

So, don't let it drip on your rims or anything of that nature that you want to keep lookin' pretty.

Just makin' sure that everyone knows this. Take your time, do it right. protect your nice stuff.

So, how does one remove the grub screw? I've heard a heat gun is necessary, but what do you do if you don't have one?
