• 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 The previous version was outdated and no longer supported.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!

Master Cylinder Bleeding

I just spent 3 hours trying to bleed my new rear master cylinder/rear brake system. WTF am I doing wrong? I think I have got it,(feels firm) but if I crack the bleeder under pressure there are some bubbles that appear. Is this an issue? Please tell me a way that works easier than this.....And I tried everything, back bleeding, front bleeding, even side bleeding. Syringe, gravity, etc.

This is the first time I have tried bleeding the integrated system. Is there any difference from the external reservoir ones from the 06-07?

I am to the point where I think someting else is wrong, but you never know.

HELP ME!!!

Sounds like you've done everything I would do....

Do the bubbles happen each time the same amount?

Pinched o ring?????:excuseme:

I'd say ride it,let it heat up then try once again to bleed.

Very small bubbles but not every time. Almost went through a bottle of brake fluid.
I am going to ride before the next race to make sure it is right. I have never had this much problem changing a master cylinder before.
 
I have also noticed that regardless of how its bled...very small bubbles still appear...the pedal had longer travel than before...and yet its reasonably firm.....

I think you will be ok after a short ride......mine did that after I replaced a caliper...after I rode it...there was no problem


I dont know why but:professor:...my theory is the square cut seal in the caliper...which also acts to retract the caliper piston slightly to lessen drag....takes a while to re establish itself....


some guys I know will lock the pedal down overnight....and its fine in the am's..for that same reason

Ok, now this is what I am talking about. It often felt tight but then bled back into the cylinder. So it could be normal the way it feels to restablish itself....
 
If it's a husky, they fly so fast that you don't need brakes.

I have done the same thing. Tie your lever back or down and let sit overnight.
 
Even after bleeding my brakes don't always feel firm. Maybe one of the banjo bolts need to be tightened a little more.
 
I plan on testing it tomorrow. Banjo bolts are super tight. Could it be the copper washers? I had to replace the ones on my head bolts because I was leaking coolant???????

you are never supposed to reuse the copper washers. they seal once and they are done. try your local auto parts store they should have some.
