I have just got my master cylinder and booster back on and bled the system and have notice there is a bit of freefall before the brakes take. I am pretty sure it was there before but have now only really noticed it.

It is not a squshy pedal to where it grabs like when there is still air in the lines, it just has no pedal then hits a great solid pedal. I was thinking could it be something to do with the adjustment on the rod fron the booster of the rod to the booster from the pedal?

When I fitted the master cylinder I had to tighten it down because the rod had already hit the piston before the nuts were wound right down.

The rod must not be putting weight on the piston as the master cylinder is being tightened up. You must have a small amount of pedal freeplay before the pushrod actually operates against the piston.
If you have no free play you may end up with you brakes starting to drag as the fluid warms up with will cause it to expand and put the brakes on further.

the rod is on the piston because I had to tighten it down onto it. I was thinking about tightening the rod from the pedal to the booster and seeing what happens, I might try that when I get a chance and have some motivation It has been like that since I got it about 8 months ago so theres no hurry.
