    Brake problem

    I have a 95 A6 recently the back offside brake hose came apart where it joins the metal brake pipe resulting in complete loss of fluid and brake failure.

    I filled the reservoir and pumped fluid through to find where the break was.

    I got a reasonable mechanic I know to replace the broken hose.

    But when he tried to then bleed the system from the same rear offside bleed nipple no fluid would come through after a lot of trying different things he disconnected the brake pipe at the abs pump and no fluid came out when the pedal was pumped. So he now says i need a new abs pump.

    what i don't understand is how i was able to find the fault by pumping through fluid with the pedal if no fluid was coming through the abs pump.

    Can anyone shed any light on this for me please , because I don't want to replace an expensive abs pump if it is not necessary thank you

    You need to bleed the ABS pump using VAG-COM to open the valve.
    You cannot bleed the pump without it, it VERY unlikely the pump has failed.

    The problem with common sense, is that its not that common.
