    Gunson Eezibleed is what I use - makes the job so much simpler.

    Doing it old school is a bit trickier - there is sequence to do them in. And you need a mate to help you. but i can explain the process if need be....

    The eazibleed thing screws onto the top of the resevoir and pushes the fluid through. Pay VERY close attention to the level of fluid - you can't get air in the lines!!

     Bleeding sequence

    1. Rear right
    2. Rear left
    3. Front right
    4. Front left

    Says it the fluid pressure unit should be no more than 1 bar. So if you're using an eezibleed and a tyre - make sure its no higher than 14.5psi

    Yes

    On the MK4 golf, you need to use vag-com to get air out of the master cylinder and/or the ABS pump after a brake fluid change. Do not attempt to pump the brake pedal like on other cars, as you will bugger the seals in the master cylinder! Always use a pressure bleeding kit like you have bought Smile

    If you're doing a simple fluid change (without dropping the previous fluid); air shouldn't even get into the master cylinder/abs pump because you are just pushing new fluid through over the top. But yeah - good call veedubdude.

    It's supposed to be furthest from master cylinder first, so really it should be

     

    1)  Rear Passenger side

    2) Rear Driver side

    3) Front Passenger side

    4) Front Driver side

    In my defence - my sequence was copied fromk the ElsaWin Workshop Manual.

    Guess it depends which way you look at the car. The sequences tie together if you look from the front LOL - but that would be a bit retarded. But then again most of the mechanics at the dealers are!

    My guess is that ElsaWin is written for cars in LHD format (ie most of the world!), as the master cylinder would be on the other side to our RHD cars.   :)
