also might need new pads if they got soaked with fluid, did you put the spring back in.

Sometimes you have to take the rear caliper off the mount and set up your brake line nice and vertical and then try bleeding the air out the top.
I dont know about Harleys but on BMWs I have had to take the whole damn system off the bike, mastercyl and all and set it up hanging vertical from the shed rafters and bleed it, then put it on the bike as one piece.

IMO nothing beats this method ...

Brake Fluid Bleeding w/Syringe

You can buy the 60 ml irrigation syringe [not an injection syringe] at any drug store, especially one specializing in home medical products. I paid $2.00 for mine a few years ago. Another guy posted about using a syringe from TSC, used for cows or something.
  1. discard the needle from the syringe
  2. remove lid from master cyl and set it loosely on the master cyl; it must be off of course, but the m cyl must be covered to prevent the fluid from squirting 10' across the shop
  3. attach a short clear plastic tube to the end of the syringe; i use tube that is "too small" in diameter - this is important to get a really really really tight seal on the bleeder; i have to force it onto the bleeder with a needle nose pliers
  4. use the syringe to empty the m cyl; discard this fluid
  5. fill the syringe with new brake fluid
  6. let stand for 5 minutes or so for the bubbles to rise out of the syringe/tube
  7. attach to bleeder
  8. hold it upright and fiddle with the tube until air has risen into syringe
  9. loosen the bleeder
  10. slowly squeeze the fluid thru
  11. do not release pressure on the syringe without tightening the bleeder - some fluid and possibly some air may get drawn back

Mick: ive seen your prior posts and used this syringe method twice, still little bubbles as of last night

Hogmania: i have brand new pads on there and i have set the brake pedal push rod with about 1/8" play

Hopper: i guess ill try to take the whole system off of the bike an bleed it but i will have to take it back apart to reinstall it, right??


i have another caliper rebuild kit coming just incase i find any leaks from the piston seal.
but really guys im at my wits end with this shit.

i bleed a whole bottle of fluid thru last night, using syringe and old fashion method. drove it around the block, now i have even less brake!

then i cried myself to sleep.. if i cant get it this weekend. im gonna have to take it to an indie - after i save up.

the think is, i live in an apartment right now, so i cant just get knee deep in it like i used to.

ive honestly considered rolling it into the living room (which ive done before). but if someone catches me with the bike in the frieght elevator, i think ill get evicted. trust me i have thought about it.

how much to you think a place would charge to fix this problem?

Pics might help. I wonder if you have the M/C put together properly. If I remember correctly, there were a couple extra pieces in the last rebuild kit I used. Ya really shouldn't need to double up on the o-rings. Sumpin' just ain't right.

Have you successfully bled brakes before? It is a bit of an art. I was taught to bench bleed the M/C first, fill the lines and calipers with a syringe, then hook everything up and bleed what little air is in the system.

Stay away from shops unless ya know them real well or have a seriously good recommendation. Often they will take yer money and leave ya disappointed. Do it yer-damn-self. Not only will ya get the thrill of satisfaction, but you will know it's done properly.

ito this point i have literally but about 5 bottles thru the system (ironically, ill be doing this to myself also when i get off work

no, this is my first time bleed brakes on a bike. which is actually the "smallest" job ive had to do on it thus far.

i seriously need whatever art or force that it takes to do this, becuase it probably didnt take you this long to bleed your first bike.

i have an extra brand new master cylinder, came completely assembled, that i can put on.

i dont know what else i would take a pciture of??
i guess i can try to show the bubbles coming up thru the m/c (range from large to white swirls)

picture of me trying to find were they installed the ass on this bike so i can kick it!

I had a master cyl that was crome, that sucker leaked same way intil I "honed" the cyl... that took the polish off the crome and gave it the rough surface it needed to seal. second problem was the brake light switch (i'm not telling you to replace) just what i did. Last i did the reverse bleed like Mick said and it's been fine for many years now.

Take a deep breath, and relax.....clean pads with brake clean if contaminated. there could be a air lock bubble in master.... just give it light pumps (like taps not depressing all the way watch for bubbles and when that seems to stop "maybe it will be resolved"

the light taps slight movement is ussually enough to work it out. depressing all the way won't
the double o ringgggg remove.

yeah, its that same ol' chrome one.

i guess ill go get a 3/4" honing tool? on my way home today. or did you use something else to hone it??

i replaced the swich from the beginning and tephlon taped it, no leaks on paper towel or by sight/touch.

i have been doing light taps. but is seems when i would press it in all the way, the big bubbles would come back. so i start alternating half strokes with small taps for a while.. still nothing
