brake in hell

Post by 164EVER »

Absolutely impossible to have pression in brake sytem although all is new, pump, callipers, hoses, pads,...... :evil: :twisted:
There are NO bubbles at callipers only brake fluid very clean.
I don't understand what happens.
Does anyone has an idea.

Do you have ABS? That could mess up the braking (release pressure because it thinks it's slipping).

Check the sensors and the unit.

maybe I found the reason:
supress the ABS means replace the 22mm pump for a smaller diameter 20.6

What do you mean by that, are you using another ABS pump?

Photos of the pumps would be good 😊

no ABS pump is off the car
I red that if ABS is off I have to take of the brake pump and replace by one with a smaller diameter :: 20.6 in place of 22.2
Could it be right ??????????

I hope you found the explanation to this. I have no idea what would be the solution when removing the ABS pump...
