Np Pressure in Rear Brake

[anutz]

Just a thought, Is the pin that holds the pads in good condition? They develop grooves over time and the pads will sit in those grooves and be unable to slide back and forth. So the pistons only half push the pads and then they immediately go back to the outside position once the pressure is released and this gives a spongy feel on the pedal/lever.....

Good point, also something Unfazed mentioned in another thread to me i got my caliper from the USA and the pins are not in fantastic shape, i did wet and dry them, however they may actually still have enough of a groove to cause issues, so i have ordered some new ones, cheap enough and will put them on as well...
