Normally for my car Brake pedal was not going down, but when in emergency the brake was applied and ABS was activated the pedal was going full down by making "Grrrrr" sound and when releasing pedal it is coming "chooon" Sound like air. So This sund comes whenever brake was applied. But after few days the problems gets solved but again appears when brake is pressed in emergency.
For few days now the pedal is always going down and that problem is not getting reset as it was reseting after few days
Now I have changed the brake Master Cylinder But problem Remains Same.
As per technician this sound appears from ABS Modulator.
Please give better suggestion to clear this matter

Regards,

yasir

That is a normal sound of the grr, what is happening is the abs motor activates and controls brakes much faster thatn you could ever do. The choon or whoosh sound is the vacuum booster all of that is normal. Just try not to do the emergency applications so much.
