Hi recenlty blown my turbo and pulled it to my mechanic's garage without the engine running. Press the foot pedal a couple of time when pulling. But since then I've started it to move it into the garage and the brake pedal is hard like when the engine is off! Can anyone help, as the brakes were fine when the turbo blew, is it linked to the turbo probs or something to do with when I was pulling the car???
