Braided brake line question.

Young_don · Dec 2, 2011

I fitted some race lines to my bike and bled them with a mityvac and manually as well. As far as I can tell all air is out of the system and the brakes are working great. Better than before.
But my question is, how firm should the lever be? I can pull it easy for about 1/2 inch of so then it stiffens up but if I try hard I can bring it in about 1/2 to the grip. Is this normal.

Pends on where it's adjusted too. On the closest settign to the bar - maybe, you coudl get it too the bar, but on the furtherst out - no way.

Put that bars on full lock so the MC is at the highest point and cable tie the brake lever to the bar. Leave it for about 12 - 20 hours, and gently tap the lines, calipers every hour or so. And keep tensioning the lever back as well.

This will help all the small bubbles escape over a period of time.

Release the cabe tie and pump up the lever - you will prolly be amazed at how firm you can get a lever by doing this.

Does this really make a differance? I would like to try this as the dealer that assembled my bike did not bleed the brakes the best, and they are very spongy..

So first question, is this ok for the brakes, to hold the lever down for this long of a time? I think it would be fine, but I don't like to guess on $$ items like breaks.

Also do I crack the bleeder valve after the 12-20 hours and get the air out of the lines, or is the air bubbles going up to the reservoir and I do not want to crack the valves at all??? ( I know I need to bleed them the normal way first)

+1 This method works great for getting small air bubbles out!!

My brake lever has hardly any play. Adjusting the lever should just change how close it is to the bar, not how much room you have before the brakes engage. Getting it about half way to the bar seems on par tho. Unless you mean 1/2 inch from the bar, that seems a little much

this is about the best way i know how... tested and worked.. holding presure on the brake lines with the lever in doesnt really seem to make a difference.. regardless if there is pressure or not tapping the lines might work, but locking the M/C down just seems pointless to me.. ive done it before, but moto joes method seems to be the best ive tried
