tips for bleeding left front caliper on '83 GL1100?

Postby BigSwede » Sat Mar 03, 2012 7:15 pm



So... got my brakes all back together today, unfortunately the braided steel lines I bought on ebay didn't work: the fittings on the lines for the hard lines from right front & rear have the wrong threads :( :o :x so I had to use the nasty old rubber lines :cry:

Back/right front bled OK and work fine, my problem is that I can't get all the air out of the front left. I used a mityvac, put teflon tape on the bleeder screws, rebuilt all calipers & both master cylinders, made sure all the little passages were clear, new honda OEM pads all round. I have used up a whole 32 oz bottle of fluid between all the brakes but the front remains "mucho spongo" There is pressure and it works, just not very well.

the front left has the one braided steel line on it that fit as it's got banjo fittings @ both ends

Any suggestions? also what's a good source of braided steel lines that will actually fit?

Thanks, Mark

I would put the original line back and see if it works .It worked with the om line right . That's were I would start. than look at the washers on the new line .the old one may not work on the braided line Good luck my 2Cents

Seeing some posts about cracking the banjo bolt @ the M/C with the lever pulled in, I tried that a few times in between more vacuum bleeding attempts but no improvement.

Last night I loosened the handlebar clamp for the M/C and slid it along the bar until the end with the banjo bolt was pointing down instead of up (making sure the lid was screwed down tight), then clamped the lever down and left it overnight.

This morning, unclamped the lever, waited a few minutes and moved the M/C back to original position and lo & behold the sponginess is gone! :D :P So it would seem that there was air trapped in the banjo fitting, which is the highest point in the system.

Oh...I totally forgot about that one! Clamping the lever down and leaving it overnight often helps. Air bubbles that may be too large to migrate through small openings are compressed by the lever being squeezed down, and can then migrate upward to the reservoir overnight.

I contacted the ebay seller and he will send me the correct hoses, even though I bought them back in December. :D
