Dear community,
Maybe someone has a idea where i should check.
The Problem is, my servo does not deliver support to braking.
There is no difference in braking power whether i pull the vacuum hose of the engine manifold or not.
The brakes itself are working.
I can stop the car by pressing real hard (without servo power)
The brake works on all four wheels.
I already checked:
- the little white servo valve. (I opened, cleaned, the diaphragm looks good and feels soft, when pressing the pedal the valve opens and you can hear the pressure equalization)
- the brake servo. (the diaphragm looks also good, feels soft.)
- replaced all hoses with new ones (also used hose clamps)
- the engine delivers a remarkable suction on the manifold, this is enough for sure
what should i do?
