Bleeding ABS II
« on: August 27, 2015, 08:23:19 AM »
Ok so I have read up here at Motobrick about manually bleeding the ABS. Where is the reservoir?  Does the ABS share the same reservoir with the front and rear master brake cylinder reservoirs?  Will this help with continually faulted ABS system? (I need to bleed the brakes anyway, just wondering if it will help?)  My ABS is so intermittent, I get ready to tear it out and it works again!
Thanks,
Bizz

Was it something I said?

 So I didn't get any expert advice?(quintessential or otherwise!?) I guess no one here has done it before? :musicboohoo:   Going to Bleed the rear ABS, then the rear brake as I understand it is to be done.  Hope I get it right?  And I have got to say ABS...............WOW  As drake recommends to try and lock um up a few times before ya bleed um.  I did it on my way to work and on my way home a bunch.  I am a believer.  It is by far the fastest stop I have ever been able to achieve.  It  will almost put you over the bars. Just HOLY SHIT!!!

Hey Bizz, the only reservoirs are at the master cylinders (front and rear).  Keep topping those off as you bleed at the ABS pumps first, calipers second.

Re your comment on rear caliper drag.... It could be as simple as the master cyl piston could be not returning all the way and causing the drag.

Or, in my case this year, I had to replace the caliper seals as they were still original and no longer as pliable as they need to be.

BTW, you should be able to get caliper seal kits/ and or master cylinder rebuild kits from Motobins, as US dealers are no longer able to buy them.

Don't ignore it. There have been some fires due to the caliper over-heating the disk and igniting the rubber boot on the final drive connection.

Scott,
Yes, I figure there is a rebuild in my future.  Since this is quicker and easier, I thought I would try this first.  I don't want my bike to catch fire!  :mbird  That would really suck. I saw the recently posted vid of that bike burning. SAD,SAD day. :falldown: I am working hard trying to get her ready for a road run to Colorado for a wedding.

When you get to the point of a caliper piston seal kit, the rear caliper kit comes with the piston seals and new stretch bolts(but I didn't split my calipers, as many have warned against doing). The front caliper kits come with seals and new pistons(again I did not split them). You won't believe the amount of crud that builds up inside a caliper--
