    Think everyone cleared it up with more bleeding.
    However I think bleeding it more might help.

    Bled straight through by pumping the pedal method and also pressure bled

    The pneumatic bleeders are quite good for bleeding up hydro's.

    I would of thought a pressure bleeder would of done it.

    ^ not that relevant, a hydro will stop the engine no problem. It's not bled properly, they can be a pain, IIRC I did it by pressing pedal, open bleed, pedal almost all the way, pull hydro all the way, close valve, release hydro, release pedal. It was quite some time ago though, just try every sequence you can think of until it works.

    when you're bleeding it, you're holding down on the foot pedal and holding on the handbrake, right?

    i don't think you did. sounds like some air has been pushed into the rear brake lines.

    When you bleed you need to open the nipple, then apply the pedal. Otherwise you get cavitation in the fluid and it wont push the air out as effectively.

    i just pulled the hydro and pumped the foot brake untill i couldn't hold the hydro up any more and then bled at the back. Ignored the hydro for the fronts. Did this about a million times

    i had a similar problem with a crap pedal and the hydro was shit.
    what cylinder are you running. if it's a 0.7 try swapping it for a 0.625

    How I did mine was-

    Bleed it up
    Take it for a drive
    Bleed it again
    Went to a drift day, focused on giving the hydro as much use as possible
    Bled it again and it was fine.

    We were bleeding the manual way, press brakes down pull hydro, open nipple, close nipple, repeat.

    put new rear pads in. They're like £12 from euro. Don;t need to be fancy ones but the ones in there are probably 10 years old and glazed to fuck.
