  • [Corsa D 2006-2014] Corsa d 1.2 abs pump no o/s/f brakes

    Hi all new to this forum have posted this in another forum as well.Ive had my corsa d 1.2 2010 for a year now and have recently
    noticed it pulling to the left when braking
    i checked the brakes all round and found that the drivers side front was not getting any brake fluid to it i have tried
    bleeding the brakes and when i loosen the nipple for this one the brake peddle stays hard i have traced the brake line back
    to the abs pump and when removed there its dry no fluid coming out where this pipe goes although there is fluid out of the
    other 3 brake pipes out of abs pump does anybody have any idea what this could be i was thinking new abs pump but have seen
    a post on another forum from a few months ago that tried that and didnt work.
    Things tried so far:-
    ive changed brake master cylinder
    changed brake fluid
    checked all relevant pipes are clear
    check all recalls are up to date with car
    checked diagnostics with no error codes
    Really stumped with this one any ideas would be much appreciated thanks.

    Welcome to the Forum.

    Struggling to grasp this one a bit.
    If the car pulls to the right when braking, it means that the N/S (NEAR) side front brake is lacking in performance and that the OFF side brake is in fact working.
    Just imagine that the O/S/F wheel is locked, then the N/S/F will 'push' the car to the right.

    Does ate ABS light come 'on' and is there any strange noises when you brake?

    Sorry for the questions and no answers.

    Regards

        To be honest the most logical next step is to replace the abs unit. If you'd only said there was no fluid at the caliper I'd have suggested checking the flexi first, but if the pipe out of the abs unit is dry then that's the most likely source of the problem.

          Thanks for the reply Taurus if i replace the abs unit does it need to be reprogrammed or can i get one from scrapyard and its just a straight swap over

            Have a look through this Vauxhall Workshop Manuals > Corsa D > H Brakes > ABS 8 > Repair Instructions > Control unit for ABS hydraulic modulator, replace (ABS 8.1; ESP 8.1 ESP)

            I know you said you've checked all recalls are up to date in which case it sounds like the valve inside the unit that has failed, build quality on the D isn't all it should be. But they was a recall on them for the ABS unit so make sure that's been done if yours is affected.

                  Bringing up an old thread think my mate is having the same issue. How long is the part number and where can it be found?

                    I would suggest that you have a look for the part numbers on the Auto Vaux website catalogue. You will need to put in the vehicle details to make sure that you find the correct part.
                    These people sell genuine Vauxhall parts, but are generally cheaper than buying the parts from a Main Dealer.
