Don't suppose anyone has experience with bleeding Honda's bloody C-ABS?

2008 Hornet, bled the front and rear brakes after a pad change, and can't get the lever firm enough. It's still rideable, but too spongy and goes to about 1" from the bars with full pressure applied.

Did the bleed in the prescribed order (front left, front right, front centre [rear linked piston], rear) initially using a vacuum pump, then a final go with old style bleeding.

Any tips welcome. Thanks!

I believe there is a channel called kevs shed on YouTube that details it for the VFR - assume it's very similar to this.

Are you sure its not the new pads, they maybe softer than the old ones? just a thought

There's a thread of mine on here from 2015 where I refitted the C-ABS system to my 2013 Fireblade.

There were 17 A4 pages of instructions.

Yes, it was a ball ache.

Having recently managed to completely suck all of the fluid out from my clutch, with a vacuum bleeder, and completely losing the clutch lever, I feel your pain..!

After about an hour and half of bleeding (all ways) on my VFR800 the only way I could bring the lever back was to reverse bleed it. Luckily I had a syringe (a large one!) and managed to push the fluid back from the bleed nipple through to the master cylinder. Which managed to get rid of the air that was trapped somewhere in the system.

Without this I was properly stuck.! I haven’t touched the linked system. Have left that well alone, just done the simple front and rear, by dragging the fluid through (this time making sure I didn’t run the reservoir dry!).

It may work/may not, but worth a try…? Not sure if linked like the VFR, but you could try and push from the rear bleed through to the centre bleed first, as I found the fronts straight forward...
