I've just given it ago and it's helped but the pedal still goes to the floor when the vehicle is moving. I'm just going to keep playing with it and see if it gets better, as the return spring's are fitted correctly. Many thanks 👍

My series 3 1973 has had new drums, pads, the lot! I bled the system up and the break pedal goes to the floor applying some pressure to the breaks but not enough to hold it on a slop. If I press the breaks twice then the pedal will go solid...
