Hi guys,
Just wonder if anyone has experienced and would know why my 2011 MN Triton's brake pedal goes to the floor with the engine running, but is as hard as a rock with the engine off. The fluid has been replaced 8 months ago, and all front and rear pads and shoes renewed - system bled, and the brakes seem to be working ok whilst driving. Just seems to be an unusual occurrence and I have noticed this question asked by many other vehicle forums - perhaps it's more common than we think. I've just not seen a conclusive answer that adequately explains this.
Cheers,
Paul
