hi. I have changed the brake booster in my car. I have disc brakes in the fronts (4 piston - 11 inch discs). After I changed the booster, the pedal goes all the way to the floor. The weird part is that the brakes are exceptionally good. The pedal goes until the brakes stop the car, then as if there is another level in the pedals, the pedal goes all the way to the floor and the brakes seem to hold even better, or in other words it seems as if the pistons squeeze the discs a little bit more.. Is there a problem? If yes, how can I solve it? By the way, the car is automatic but I dont know if the booster is for the automatic or not if it makes any difference..
