hi, i have a 1.4 petrol fiesta with durashift and and abs. there is a problem with the brakes, when the pedal is pressed the brakes start working but then the pedal goes soft and goes to the end. if i am stationary and press the pedal it goes firm and then after a while goes soft and goes to the floor again. i had the brake master cylinder changed a few months ago and it seem to sort out the problem, but now its the same again. any ideas if its the same again or a problem with the servo. all fluid levels are correct and theres no leaks.
thanks
thanks
