Totally p#ssed off, bled everything again using pneumatic kit over and over again and still no bloody brakes.
Hit the exhaust studs with some mig power, still cant get them out, another weekend wasted
.
Well, i got back in there after 3 days of pumping and cable tie, still nothing
So after a chat with Blue when he collected my panniers, he told me about his clutch master cylinder failing on a trip to France, so tonight to prove the cylinder i fitted a Brembo master cylinder from a Ducati and pushed fluid from the caliper up through the lines filling the master cylinder, pumped the lever,nothing. I then bled the system again completly, still nothing, with no air coming out of the calipers or ABS. When pumping both front and rear i can still hear swishing in the ABS unit so the only conclusion i can come to is there is a problem with the unit and air is trapped. After weeks of struggling and wasted time i think i have two choices, take it to a dealer or bypass the ABS as i have run out of time.

OK, i did cut the 3 day routine short by a day but only cos i had an idea the master cylinder was u/s.
So master cylinder is ok, got to remove the Duke one and reinstall the original, taking it to a dealer is a last resort as i suspect you are right they won't do anymore than i have and putting it together and lumping it into a van is not ideal (dont really want to hump a GS about with no brakes).
The other odd thing is why am i getting the same on the rear as they are separate circuits as far as i know ?
I need to concentrate on these abs pots i am thinking of breaking one of the unions and forcing fluid into the thing as i have not much to loose with the next option being to bypass anyway.
Main reason for post after post is i get the niggly feeling its something simple that i have not thought of, thought i had cracked it when the BM tec said you need to force the pistons back in the bores and hold them there but no
Yes i do have a few bikes (Richie) but none that would survive the winter salt an brine or whatever caustic shite they are going to chuck about this year, the Pan sailed through last year no probs but sadly sold it (mistake me thinks), i have prepped the Blackbird as backup but not ideal winter hack (too nice) Busa is 10 months old and don't want to get it dirty ha. Bandit is for sale so don't want to get that dirty either. The GS was bought as a project and to get through the winter (here already !).
As a note i was at George White in swindon the other Sun and was looking at a blokes Street Triple now i like them but what that would look like after a winter is anyones guess.
on the 3 day routine. It was anyhow just a reference. The important thing is to understand that if your problem is air trapped in the system, applying a strap to the lever and tie it to the handlebar will do the trick and the more air you have, the more time you will need to get rid of it.
