Quick update, Brakes all sorted!!!!!
The sloppy low pedal was all down to some adjustment on the pedal to servo linkage?!
Thanks to steveppp and dukeboy for there thoughts and input today but with a quick twiddle and some adjustment of said threaded linkage under the dash the pedal now feels firm and brakes bite straight away.
Well now its time to just drive the blooming thing and keep a eye on all the new parts fitted and make sure nothing leaks!
