I just changed my breaks on my %26#039;92 ford escort. When the car is on there is no break pressure, however when the car is off the pressure comes right back. This is after the breaks have been bled at least 10 times on each side and new break fluid has been put in.
When the car is turned on and there is no pressure and I go to drive it the front breaks are locked solid. |||Sounds like you%26#039;r brake servo has gone,that%26#039;s the round thing the brake master cyl bolts onto.Test like this,start engine rev then turn off,depress the brake pedal several times until it goes hard,then,WHITHOUT removing pressure with your foot on the brake,start it up,the pedal should dip down towards the floor.anything apart from this result means the servo is shot.|||You will need to replace the brake booster. It works off engine vacumn thats why there is a difference when the car is running.
