    Brake bleeding

    Hi there , new member from UK , hope you dont me joining you guys ?

    Info needed on brake bleeding please?

    I recently replaced the front pads, and wanted to flush the brake fluid out,

    I used the x2 man method , one presses pedal , the other works on the caliper bleed nipple,

    However I think i let the master cylinder level get to low DOH !!! and now I have alot of brake pedal travel

    I tried re-bleeding at the calipers but made no difference,

    I have borrowed a vacum bleeder now and will try that ,

    What is the bleed sequence please ? bare in mind i have a right hand drive CRV , so the master cylinder is on the right side,

    Also any other advice is greatly appreciated

    thankyou

    Paul

    bleed from back pass,back driver, to passenger, driver... use a clear tube to see the air bubbles. or you can open all 4 valves and let gravity bleed all 4 for you.

    Clear the brake fluid in reservoir first.
    Then fill up with new brake fluid.
    Most important to know what grade of brake fluid you are using.
    Dot 4 and dot 3 are interchangeable, but not dot 5
    Then pump the master pump until it is tight to clear most of air out.
    If you cannot pump the master cylinder tight, most likely the master cylinder has failed, no use bleeding, as a lot air will get into all your brake lines and ABS system.

    Yep with engine on, the vacuum assist will put more pressure on your pump so there must be air in your brake line. Most likely your master pump is OK.

    Normally you can bleed using 1 pint of brake fluid, but now you will need 2 pint of brake fluid.

    Bleed at least half a pint per wheel to make sure all air bubbles are drained out. Remember to keep on filling the reservoir else air will get in the Master pump.

    Best of Luck.

    Since you have a 2006 you probably have ABS.

    If you have introduced air into the ABS pump or lines, you MAY need to energize the ABS in order to purge the air.
    Go to a wet, empty parking lot and jab the brakes to invoke the ABS. Then bleed again.

    If you are unsuccessful, you MAY have to pay the dealer to bleed the brakes (they can energise the ABS pump with their diagnostic tool).

    Good Luck.

    yep if you still fail, then like Carbuff2 said.. you need to activate(energize) your ABS.

    A bit dangerous tho, with spongy brake but still you got to do it carefully.

    ABS can easily on a sandy,wet or slippery area, just brake very hard and when the wheels lock, ABS will activate.

    Best of luck.

    Anyway on another thread, cleaning the brake clips seems to help spongy brake, you can try it when bleeding.
