• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Front Brake Issue - Driving me nuts.

I changed front pads a month or so ago and ended up with a spongy lever. Thought it was weird, didn't understand it, but figured it was a good opportunity to flush the system. With a fresh unopend quart of Bel Ray Brake Fluid, I commenced with bleeding that night via my trusted vacuum pump bleeder. I bled, and I bled, and I bled... level still spongey. Then I tried back bleeding with a syringe from the bleed nipple back up to the mcyl. I fiddled with it off and on for another week and ended up riding with substandard brake feel hoping the jostling of the front end would dislodge whatever air still stuck in there. No luck. I even tried the suggested zip tying the lever tight to the handlebar overnight... that worked for about 10 minutes.

A week ago I had decided that I was going to tear down the master cyl and rebuild it, and if that didn't work I was going to replace the line. However , as a last ditch effort before spending money, I decided to remove the whole assembly from the bike and fiddle with it in hopes of dislodging the air. I held the setup by the lever, letting the caliper dangle and started "tapping" on the caliper with the rubber end of a screwdriver. I tapped all over the caliper, the line and the Mcyl. Did that for about a minute probably, then stuck a piece of flatbar between the brake pads.. two pumps and the problem seemed to be solved. Crazy stiff lever... THEN, I put it all back on the bike and BOOM, spongy lever. ARGH!!!

Should I replace the line now? Rebuild the Master? Any other tips? Help! :)
 
Ahhh yes. I remember reading somewhere that the seals sometimes go bad and allow air to bleed into the system. Good call.
