Symptom: The customer reflected in the cold car after the brake pedal brake, but the hot car after all normal, so invite customers to factory inspection. Troubleshooting: Taking into account the vacuum when the brake pedal, first check the engine section, to confirm whether there is a vacuum leak, the vacuum tube connection everything is normal; then check the engine operating data, it seems no problem; then it can be considered transmission failure Cause flameout?
