Bleeding brakes

[clutch]

Hi all, I changed my brake fluid with a mityvac but am not sure if there is any air or not in my brake line after I changed fluid with the mityvac because I could not get that great of a connection with the clear tube and it seemed like I was sucking a lot of air when I was changing brake fluid with the mityvac.

How do I know if there is air in my brake line?

I heard if you zip tie the brake lever down over night is a good way to get rid of any left over air, does the reservoir cap need to be open when doing this?

when i bled my lines i just kept going till i didnt see ANY more air bubbles coming out. i've put about 250 miles on the bike since without any problems. not sure about the zip tie idea, kinda interested to hear if anyone has tried this.

If there is any air at all in your lines the brake lever will be soft and mushy.

Your not the only one who has had this problem with vacuum pump bleeders.

:cheers:Keep the reservoir cap off overnight with the zip tie on the brake lever. make sure there is enough fluid, then go to bed.

If i keep cap off overnight, will moisture get in there?

This is my first time ever bleeding brakes.

When the lever is pulled, it closes off the fluid supply and directs pressure to the brake lines - so zip ties will will do nothing bur put pressure on the pads, leaving the cover off will allow contamination of the fluid .

When using a vacuum bleeder, I make sure the last few pumps are without the vacuum attached (just the hose) this will give you solid fluid in the hose, or let you know there is more air.

for the Master cylinder, wrap the banjo bolt with a rag to catch the fluid and GENTLY loosen the bolt while pressing lightly on the lever.
Tighten the bolt when the lever bottoms out.
DO NOT RELEASE THE LEVER WITH THE BOLT LOOSE - it will suck air in.

The Clutch is a pain in the ass due to all the kinks and length of the line and might have to be reverse bled to fill the line.

Just did Speigler SS Lines all around and it was not too bad a job.

Rinse all spilled Brake fluid off immediately it attacks paint.
Clear water is best because elements of the brake fluid will remain in the soap residue left behind.

Definitely wash the bike when done but rinse well.

:oh yeah: the clutch line took for ever to bleed! everything else went smooth for me.

also, i just used a one man bleeder, the $5 one that you get from harbor freight tools with the tube and little bottle with the magnet on it.
