Ok, I changed the brake fluid in the valk tonight, the front brake lever pulls almost to the grip. Do I need to re-bleed them or just add fluid? Or is this normal?
Thanks
Ed

Time to redo.
What method did you use to bleed them?

I heard you can get the air out by tieing the lever back and letting it sit over night. I've never tried it this way. A might-vac can be used with great success.

Took more than once when i did mine.  A second set of hands is VERY useful for front and/or rear brake bleed.  RIDE SAFE. |

Just did the front and rear brakes, and clutch on both my bikes. If you have somebody helping you make sure they know what their doing and have a steady hand if they are pouring the new dot 4 brake fluid into the master cylinders. Cover any exposed painted surfaces to avoid any contact of brake fluid and paint. I also wrapped a small towel around each Mstr/Cyl I was working on. G/L.

The old fashioned method for bleeding air from brakes should work fine on the Valk:
With the bleed valve closed, pump the lever (or pedal) several times. This should force the air to the end of the line and compress it, so the lever should be firmer and no longer go all the way in. HOLD the lever in, then have someone (or yourself with a long reach) barely crack open the bleed valve for a second or less. Mostly air and a bit of fluid should come out, so you should have a plastic tube attached to the bleed valve and a container to catch it. Don't open the valve much or for very long, or the lever will reach the end of travel possibly letting air back in through the valve. Repeat a few times and all air should be out of the system. With the front brakes you'll probably need to do both calipers.

I have not tried this on a bike but used to make life simple when I was working on cars. Take a long vac line that slips on the bleeder nipple, cut the hose quiet long about two feet. Get a old bottle from a quart of motor oil, make sure it is clean. Drill or hot puch the lid and make a hole just a smidge smaller than the vac line. Feed the vac line into the lid and down into the very bottom of the oil container. Now put enough brake fluid into the bottom of the container to cover up the hose end in the bottom. Put the hose on your bleeder crack it open and pump away. With the hose emursed in the brake fluid these is no air to be sucked back into the brake line during pedal/lever relese and the old fuild coming out just adds to the level in the container and you can see the bubbles. This let's you leave the bleeder cracked and bleed your brakes single handed. The only thing to worry about now is keeeping your resiviour full and closing the bleeder when its all done. Good luck

Brake bleeding 101
Fill master cylinder, do not get on paint
pump and hold lever/pedal
open bleeder
close bleeder
release lever/pedal
repeat
Always start with farthest bleeder from master cylinder

"Speed Bleeders" work poorly when there is a good amount of air in the system. IF AT ALL!
They work good when there is just a small bubble of air. Very small!
They work best when just using them for a change of fluid.

I agree with Ricky-D's 1st statement. Mighty Vac almost useless if lots of air in the system.

I use a Mity Vac to pull ALL the fluid out. Then refill and flush with alcohol till empty and dry. Then refill with DOT 4 and bleed with the Mity Vac. Totally useful with the system empty. |

I used to do it the old way with a helper to operate the brake lever/pedal while I did the bleeder nipple. And keep an eye on the reservoir level. Then I bought the "one man" bleeder tool from Harbor Freight that sucks using a compressor. Much easier, but in some cases it needs more suction. Like when doing the furthest wheel on the Exploder. Works well on the bikes - so far haven't had any complaints.
