Hi, I have a GMEA scratch, I have a problem that does not stop when the blow, the pedal stays as if it had a high and durnal wooden taco. If the car is a little calmer, the car is stuck. I have changed the brake pump, the Servo brake, I have cleaned a valve that carries on the front next to the zipper of the address, I have cleaned the brake compensator and remains the same. Have if you can help me, thank you.
