[plam1972]

Hi,
I have a problem with the brakes I40 hyundai 2015.
After pressing the pedal the car does not stop and the pedal falls down.
This does not happen every time. Not errors in ABS.
Can anyone help. Thanks advance.

Give it a couple stabs on the pedal and it comes to life? Fluid level getting lower?
Brake master cylinder....

the pedal falls down.
Should that not be "the pedestrian falls down"?

[plam1972]

yes, but this for thrее days one.
shouldn't he do it all the time?
Fluid level not getting lower.
the pedestrian falls down- yes -the car is driven by a woman-great joy he's not in jail...

shouldn't he do it all the time?
