I haven't bled my wing yet. I am going to do mine just to change the fluid. My fluid is a little foggy, want to clean it up.
However -- I changed the fluid in a CB750, that was my first time working on a bike brake system. I rebuilt the front caliper as well.
I have done many cars, what I learned from that CB750 is that it is much different then bleeding brakes systems on cars. It takes a lot of patients and time to get that air out. Sometimes, it seems as though nothing is coming out every time you crack the bleeder. Time and patients and a lot of beer. But don't let the beer screw your job up. I think I went through 6 beers before I saw any action. It was tiny skirts, I mean squirts of air and a lot of bleeder cracking, a lot different then a vehical with 4 wheels and a real brake pedal.
U must have ounagy Ole Daniel-Son, wax on, wax off, wax on, wax off, wax on, wax off.

C'mon everyone with an '83 that has been persistant enough to actually get the brakes bled tell us how many hours you have in it.
I get some fluid now but no pressure in the pedal.So I'll keep at it.
Burning away good riding weather too.Its a shame,really.

Tom I am sorry to hear your having so much trouble . It can be difficult . IF your begining to get fluid your on the right path . Be sure to keep the resivoir full so as not to risk introducing more air to the system.
Can you pump up any prssure yet ? I mean with the bleeders closed off pump the brake pedal . IF you can get some pressure then bleed the front . I think it was mentioned early on, if you can raise the front caliper up ...perhaps higher than the headlight. BE sure to put a spacer in between the brake pads so the pistons dont over extend. The air will float up hill better then down . I also alternate between front and back when I am bleeding the linked system .
IF you are using a mightyvac , I find the bleeder screws need teflon tape onthe threads . If not you will be sucking air in around the threads . Not pulling as much fluid thru the system .
Another thing that some have found helps is to pull the banjo off the caliper . pinch it between your thumb and forefinger. While holding it that way , you can slowly press the pedal and the fluid will pass by your finger/thumb but you seal the air out . Once you have the lines full of fluid then put it back on the caliper. Bleed a little at the banjo bolt once its back on . Then proceed to bleed the caliper.
I am not sure what you have tried to date . Some of these thoughts might have been mentioned earlier in your thread . I didnt reread the complete thread tonight. I hope your soon past this bump in the road and out enjoying some nice fall rides. Wish I was closer and could help more.

Well thats a real nice note.Thank you for your interest.I'll keep trying.I did post one rant on the design of the system and still feel its at least deficient because no one could design a system with this kink in it and call it an advance.Too many people on here have had the same or similiar problems.Talked to the dealer today and they don't like to work on old bikes but because they know me they are willing to take a look and use their power vac on it.Of course I told them I don't want a bill for $300 to get my brakes bled.They smiled.They are so nice.They said they'd work with me.
Yes I did get some progress today.On the rear I drew about an inch and a half or close to two inches of brake fluid up the tube.No pressure on the pedal yet though.On the front I got some fluid but more wet air than anything.I did alternate front and rear and used the mityvac and the old fashioned method too.Right now the pedal is being held down with a wedge overnight so maybe that'll make some difference.Doubtful but maybe.At this point I'd take anything that moves this process forward.So tomorrow I'll be back on the brakes again.I'd say I have somewhere near 50 hours in this stupid process.Guess if I had a compressor I could use that like the dealer will.Probably would go buy one if I KNEW that'd get the job done.But I don't so I won't.I have used most of the tricks suggested by fellow members and I do appreciate their advice.So if anyone has something to add on brake bleeding an '83 lets hear it please.
Front caliper is up above the handlebars.With a stop between the pads.
Thanks for the encouragement and ideas.

OK how far have you gone yourself and what were your results.Would you let us know what the dealer charges?
My guy won't commit to even doing it.They will "look" at it next Thursday.

| You may be getting air in the system through the master cylinder piston so vacuum and pumping the pedal will never get the air out. Find a plastic bottle with a nipple cap or something similar and fill it with fluid. Remove the reservoir from the hose to the rear MC, put the nipple in the hose, bottle upside down, open the bleeders and squeeze the bottle until fluid comes out the bleeders. The MC may hold with fluid pressure on it but not seal off good enough to keep air out when trying to bleed.

| Another thought Tom . How about start at the begining. Disconnect the pressure line right at the rear master. Holding a finger tip on that port , bleed the master . Then put the line back and move to the pressure spliter . just keep moving away from the master , working out the air in each section .

| Well the pressure splitter is a problem because I can't get the nuts loose and you know how easy they strip.So I have to go get some line wrenches to get them loose.I'm not saying I won't do it but I just haven't yet...gotten the wrenches I mean.

Hi Tom, hopefully will catch you before you bring your bike to the dealer. I just did my front brake, just flushing the old fluid out and replacing it with new.
Something that I forgot to mention and only remembered because it just happened to me. My bleeder was 98% plugged. I put a vacuum system on it that I made up and I couldn't get any flow. Sqeezed the brake, only got a little wetness around my bleeder.
I pulled out my bleeder, took a small piece of wire cleaned it out from the top and bottom (or I should say from the side hole on the bottom), hit it with compressed air, cleaned out nice, now flushing is working like a champ.
SO, check your bleeders to make sure they are clean. I hope this helps. My bleeder had a rubber cap protecting it as well but still corrided the ports 98% shut.

Thank you ChasW.I did as you suggested and found the port to be clean.Although I do not have a compressor so no compressed air was used.
Here is what I did this morning.I put the rear caliper up front and bled it.
Here is the pic of that result.Even with that much fluid drawn up I can't get any pressure in the pedal.I also swapped out the line from the reservoir to the rear master cylinder as suggested in this thread.I never got that much brake fluid showing when I tried to bleed the correct front caliper.The brake lines are all clear.I had them off and drew fluid through all of them.Does this lead me to believe the correct front caliper is defective?The dealer rebuilt it for me two weeks ago.He also rebuilt the rear caliper...the one showing in the pic.Its not brain surgery to rebuild a caliper.But why can't I still get any pressure in the pedal? What controls the pressure at the pedal?A full caliper and a full brake line,right?Then close the cover to the reservoir and I should be done.Right? Please correct me...anyone?Attachment: Brake bleed pics 002.jpg (Downloaded 69 times) Last edited on Mon Nov 10th, 2008 03:55 pm by tomw

Just to be clear, on the bleed, you checked the little port on the side towards the bottom of the bleeder and blew through the bleeder to make sure it was clear.
Are your master cyclinders O.K.? Have you done anything to make sure there doing there job?

Well,well,well boys.Its done.Yes it is!DONE!As in I have pressure in the brake pedal and movement of the pistons both front and rear.
A member of this board went way out of his way to be of assistance to me.I mean out of his way like five time zones and an ocean away.
I got a phone call from agnogel in Ireland and in it he gave me the two minute lesson on either brake fluid or air in a closed system.Told me to disassemble the master cylinder and check the primary cup because he suspected it was either worn or damaged and therefore not making contact with the cylinder walls.Correct he was.So I did as instructed and replaced it with another I had in a box of brake parts that came with the bike and I had pressure right away.Bled the front and rear caliper.
May have to bleed somemore but thats for tomorrow.
So is it true then..."you meet the nicest people on a Honda"?

Yep.Those emoticons are exactly how I felt when I got pressure in the brake pedal.
Another ressurection and soon to be on the road again.Like tomorrow if I can do it.
What a place.

Thank you everyone and especially thank you to agnogel.
