Sounds like the pads need replacing.

IIR The calipers on that model are not the best and i know people how have swapped for different ones.

Or try bleeding your brakes.

Bleed brakes and see if that gets rid of your spongy lever.

Check that all your brake pistons are functional and not seized. A friend had a similar problem and it ended up being that only one piston out of 4 pistons were actually working and it also had a kind of bumpy/juddery feel when you pulled in the front brake.

We serviced his front brakes (new pads, seals, pistons and a clean) and bled them and there was a massive improvement.
