    Read ABS error codes. You probably damaged the sensor cable when replacing the pads.

    for 100% the cables are ok because I checked, the liquid does not drip anywhere, I had a similar problem with zafira a, from 2001, but I drove about 2 km and the abs light went out (I was turning the wheels on the lift, apparently the abs got lost or something like that)

    This pedal goes all the way down when you hold it?
    When retracting the pistons under the new pads, the excess fluid was vented through the vent or forced in by the pump? If the latter, I bet that the pump seals are damaged.
    We will not deduce anything from ABS until the error is read.
    And decide whether you are "he" or "she" because you write yes and yes.

    Did you only change the pads or the fluid too? Or did you do anything else with the brakes?

    Ok, when pressed, the pedal does not hold and it drops gently down to the floor, the brake is braking poorly, I am there ,,, I only replaced the fluid blocks, I did not move, on the turned off engine, the pedal after pressing the brake stays in one place does not fall

    How did you sand the edges of the blocks before installing them?

    So what, what edges. I vented the system on the principle, I had a little dot4 fluid, when I refilled (help from the car owner), the venting was LP, PP, LT, PT, on the off engine. km (I turned the wheels at a standstill, the mechanic said that the abs got lost) now the brakes are razor, the car is standing on end

    As the discs already have wounds, the new blocks need to be slightly grinded on the edges of the linings so that they adhere to the disc on the entire plane and brake with full effectiveness from the very beginning.

    A colleague replaced the discs a month ago, also in perfect condition without rims, now he has just bought pads (cash is known), as for the abs, I also do not know the term that the abs is lost, but okay, let me have zafira and I had the same thing that after replacing the abs pads it was on for 2km and the light went out. I am closing the topic, thanks for your interest and for help, I am giving my solution.
