I'm having a mare bleeding my brakes. I must have burned through 2 litres of fluid and can't get a firm pedal. I'm not really seeing any bubbles in the fluid, the odd one here of there and no obvious leaks. If I pump the pedal three times, it's rock solid. If I then wait a couple of seconds and pump again, its spongy and goes all the way to the floor.
I suspect that the ABS pump may have a air lock, but for the life of me I wouldn't know where that is in the engine bay, it's hidden somewhere.
I tried an eezibleed kit with the clamp adapter but that was useless and just emptied the tyre of all it's air.
So i'm at a loss, out of ideas.....
