Hi Guys,

Last night on the way home the front brake just became spongy, it grips then it gives way. The symptoms are as follows:
- When the hand brake lever is pulled it feels like it has resistance (grip) then gives way. Almost like there is air in the system. Did bleed it quickly this morning, no luck.
- Pumping the lever it feels like it is getting better. When holding the lever in to bleed it gives way.
- With bleeding nipple open, brake fluid flows when pumping the brake lever. I'm using a bleed-kit.
- Topped the break fluid up, tried again with no luck.

Where do I start? Hanbrake lever or ABS system?
