Had the same problem and used the ORG for advice...I put the calipers back onto the bike and bled in this irder,,,,,from the banjo bolt on the caliper, then the bleed nipple on the caliper, then followed the hose up to the banjo bolt on the handlebar and bled that...finally I undid the master cylinder from its fitting in the bar so that I could get all of the air out of the little clack tube that connects the master cylinder to the handle bar banjo bolts,,,took a while but its done.....MAKE SURE THAT THE MASTER CYLINDER NEVER RUNS DRY , KEEP IT TOPPED UP WHILST BLEEDING THE SYSTEM. I am sure that someone welse will be able to give you more advice soon though,,the ORG is awesome for it,,,

Nice and simple/basic way, remove the reservoir top and top it up with fluid. Place an 8mm spanner and a piece of hose on the bleed nipple. Pull the brake lever in and undo the nipple, tighten the nipple back up and then release the lever. Do not release the lever before tightening up the nipple, you will draw air back into the system! Repeat this process, whilst insuring the fluid is above the minimum line in the reservoir, until the fluid starts to run bubble free out of the nipple. Repeat the process on the other side, the lever will start to feel harder to pull (bear in mind the lever will only start to become harder to pull when both lines are bled).

Once both lines are bled zip-tie the lever back and leave over night, this will force the air to the bottom and in the morning one last twiddle with the nipples will release any trapped air.



There are other methods and gizmo's which you can use, however as a bike carrys very little fluid I find it only takes a maximum of 5 minutes per line doing a dry system.

Ricky, where are you based? If localish, i'll come and do it, its will only take 10 mins or so.

DDs method is what I've done in the past and works very well. Anyone got any advice on (or better yet, a guide to) using a Mityvac to do this as I have got one and am keen to try it out. TIA.

Never mind your bleeding front calipers, what about my sodding carbs, eh?

Crikey, facetious post in straight-bat reply shocker. Wasn't expecting that.
