Bleeding brake.

[wolfheze]

Can anyone enlighten me on how to bleed the brakes? Have fitted a master cylinder rebuild kit but can't get much fluid out of the bleed nipple. The line and caliper haven't been drained so the problem is at the master cylinder. Any tips?

Did you clean the master cylinder out and check that both holes are clear 

[wolfheze]

Yes, i checked the holes visually but with hindsight i should have pushed something through the small one to make sure. The inside of the master cylinder was already very clean but I did wash it through. On doing some research it seems as though it can be quite tricky, someone suggested priming the master cylinder with the hose disconnected, makes sense but I'm a bit reluctant to try it because of the risk of spillage.

I have documented before on here on how to get the master to pump and it is with pipe disconnected, only way if its being stuborn

I found that lots of small strokes of the lever got it started. Just pulling the lever back maybe 1" at the end a few times, then some even smaller strokes and then pausing and repeating.

Is that the squeeze lever then finger over the end and release lever method?

[Spitfire]

As someone else has said I pump the front brake lever in small strokes and then one big one until no more bubbles appear, I also make sure by moving the bars to one side that the master cylinder is as high as possible.

   does your caliper have fluid in it ?

 you could  connect it all together,then press the piston in,and force the fluid up the pipes into the  master cylinder ,

Yes the caliper still has fluid in it. Have just got back from the garage after spending two hours pumping that bloody lever.! Tried priming the master cylinder and that didn't work either. I'll take it back into work tomorrow and try to strip it down again to make sure I've assembled it properly. If I muller it getting it apart  I'll buy a new master cylinder, hope I dont have to because I don't really want pattern parts on the bike.

   I  am using a D Silver master cylinder (GL1100 for twin discs) ,It looks exactly the same and works perfectly,
 I doubt any casual observer would tell any difference.

  and a bargain at approx £30

[wolfheze]

Are they still ok to use with a single disc?

He does the version for single disc as well at the same bargain price.

Out of stock. Would the Honda brake lever fit? Would like to use it if possible as it's still got the rubber end on it.

[Bryanj]

Yes the method you found has never failed for me

[wolfheze]

There didn't seem to be much suction on my finger when the lever was released so I'm thinking I've managed to assemble it wrong
