NO Brakes ??

At the weekend me nd my brother replced the top mount bush on the nearside front (UK Right hand drive) Didnt fully drop the hub etc just un done the top 3 bolts and tilted the strut out of the wing to replace.. all was fine until drove it off the ramps and onto the forcourt..

The brakes went soft and need a full pump to the floor before having any brakes??

Sounds like air got into the system but we never opened the lines??

I have now replaced the hard brake pipe from the calliper to the flexi ( it looked as if that could of twisted and deformed so to rule that out I just replcaed it ) and now bled the brakes until there is no air out of that corner.. but still the brake pedal needs pumping until it has bressure?

I have checked to ensure the disc is flush and not pushing the pads back not that

Could the master cylinder just go like that?

PLEASE HELP!!
