    Hi, after some tips and advice on bleeding the brakes on my s3. Kinda ballsed it up today, emptied the whole system and then tried to pressure the new stuff through. kinda worked but pedal just goes to the floor.
    Anyway, can someone please tell me how to bleed the system properly? And I have access to vagcom if i need it.
    Thanks in advance

    whoops, emptied, now system is gonna be fun now as its probably full of air, ideally need 2 people, one to fill up the reservoir, make sure it doesnt go below minimum at all, also they would check the fluid for air bubbles, cleanliness along with undoing nipples & doing up, the other to sit there, pump fluid through & hold the pedal in position when they're filling up the system & tying of the nipples, thats how we did mine recently, idealling using a non returning valve in a bleeding kit so it cant suck any air/fluid back in.

    I'm sure there are others on here that can explain it better, but thats what I remember from few weeks back.

    there was 2 of us doing it today, theres no air bubbles coming out of any of the nipples now but pedal still goes to the floor. Do I need to bleed it with the car running?? And ive read somewere about bleeding at the master cylinder??

    Right, problem solved. Bled the master cylinder (what a nightmare to get too), bled the clutch, and then worked my way round the car again! All done and working now. Fitted EBC turbo grooved discs, Ferrodo DS2500 pads all round, then used Motul RBF 600 brake fluid. Just drove it down the road and the difference all ready is great. Cant wait for them to bed in

    Thanks for all the help

    I ended up just using a socket on them and then nipped them up after they'd released all the air. You can hear the air come out so not too bad.
