I am going to swap out the ugly front brake reservoir and I guess I will be needing to bleed the brakes. Having never done it before can you please tell me what is the best way to do this. I have a Haynes service manual but thought I would get some good info from here first.

If your just switching the reservoir, no bleeding is needed.. Just don't pull the lever when switching, air will only get in the system if the lever is pulled with out the reservoir..

Whether you bleed now or not, I would recommend a speed bleeder in lieu of the regular bleeder screw. You just take the old bleeder screw out, set it aside, and screw the speed bleeder in with an open ended wrench. Don't use a closed ended wrench or it might be difficult to get off due to the proximity of the banjo fitting. Hold a shop rag under the hole in the caliper where the bleeder fits, as a small amout of brake fluid will probably dribble out.

Once you have the new bleeder fully in place, fit on a piece of clear tubing, the end of which is in an old brake fluid container or something similar. I use an old container with a screw on top. I've drilled a hole the same diameter as the tubing, so everything stays in place. Next is the high tech part. Find an old boot, and stick the drainage container in that. It's very easy for the drainage container to fall over, perhaps pulling the tube out and splattering it all over. So you've got your speed bleeder, your clear tubing that fits nice and tight over the end of the speed bleeder, your draining container holding the end of the tube, and your high tech boot.

You just open the speed bleeder about a quarter turn and start squeezing the brake lever. Refill the reservoir as needed until you've run enough through to be sure that you've purged the old fluid. Don't let the fluid get too low and expose the holes in the bottom of the reservoir. With the speed bleeder, there is no more "squeeze, squeeze, squeeze, open the bleeder, close the bleeder, repeat sixty times." You leave the bleeder open while purging the system. When you've run enough new DOT 4 fluid through, and no more bubbles come out the end of the speed bleeder, close the speed bleeder, squeeze the lever a few times until pressure builds up, and you're good to go. Carefully remove the clear tube, clean the area of any brake fluid, fill the reservoir to the appropriate level and put the gaskets and top back on the reservoir.

Is the New Bonnie Speed Bleeder a universal bleeder or specific to the Bonnie bikes. Could i get this from any motorcycle accessories place or am I looking for something very specific.

I just replaced my reservoir with the Rizoma. If you use theirs, I highly recommend Teflon tape on the threads of the reservoir. My personal belief is that any time you open a closed hydraulic system, it should be bled. No point in taking a chance, especially on a motorcycle's brakes. I have used speed bleeders on cars without much luck, however, that was 10 years ago.
I am actually interested in those from NB since it is a pain to pump, pump, pump, open the bleeder, close the bleeder, then repeat a good 60 times. In another thread, someone mentioned using a syringe at the bleeder and force the fluid up through the system. Sounds fast and smart, but I don't have any experience with it.

Here's my speed bleeder - I asked my wife to pump the brake lever while I opened/closed the valve on the caliper... wives are not nearly as cheap or low maintenance as a speed bleeder. They also protest about sore forearms through the process. A true speed bleeder is soon to be ordered.

I typically leave the top off of the reservoir so that I can add fluid as needed - I end up using a lot of brake fluid to bleed. In actuallity I'm nearly changing the fluid with the amount I add.

Use extreme caution with the brake fluid - it ruins finishes like nothing else out there, save paint stripper. I put shop rags on the tank, fenders and other pretty parts while working. Then I also wash the bike with plenty of soap and water when finished to make doubly sure there are no drips. I had a dissapointing experience with brake fluid and carelessness on a previous bike!

In a different thread, ( something talking about steering dampers ) I noticed a billet aluminum reservoir, anyone know of a place to order these? @itcha, what are you going to replace your old reservoir with?

Mecchanica

If you first bleed the master, it will then pump fluid much more readily. If you have to pump the master more than a dozen times, you aren't doing it right.
