    ABS pump - pipe layout help needed

    Im in the middle of replacing the brake lines on the car

    ABS pump > front left & front right have already been replaced but the rears are proving a little difficult

    Mainly due to a certain cowboy who cut corners last time when he "rebuilt" my car

    basically he left the rear bias valve plumbed in, fitted the rear discs etc and then plumbed in the rest of the ABS system so the rear discs were controlled by both ABS pump and the rear bias valve!!!

    Thankfully ive ripped all this crap out and running fresh pipes from ABS pump to rear discs......


    PROBLEMS:
    the front 2 union nuts on the ABS pump are not marked,
    i couldnt trace the setup before due to having that gash bias valve plumbed in

    2 couplings exist underneath the bulkhead - one male & one female but cant work out which is rear left or right.

    Ideally I would replace the unions on the ABS pump itself and fit fresh pipe all the way back, but the pipes to the couplers are in good nick, and access down the bulkhead is more than a little tricky.


    SO

    Can someone confirm which unions are which on the ABS pump (front 2) as top 4 are 2x feed, and 2x fronts.

    OR

    confirm which pipe is which on the underside - the male/female coupler.


    Any help appreciated guys as id like to get the new pipes fitted today.

    TIA

    Right then......lets try a different approach




    On the ABS pump there are 2 unions at the front side - could someone please confirm which one is REAR LEFT and REAR RIGHT ?

    On a side note, these 2 lead to a coupler underneath the bulk head area.... one male and one female..... could anyone also confirm which is which here? as access is tricky from the ABS pump down over and struggling to work out which is which now all other pipework has been removed.

    TIA

    ok then

    i'll spell it out another way






    2 union nuts on the front of the ABS pump

    Both are for the rear

    Which is REAR LEFT ?

    Which is REAR RIGHT ?




    Can anyone help or will i have to find a random Astra and get it on some ramps to follow the pipes all the way back from the calipers??
