There is a mod on sheps global site where you chamfer the leading edge of the shoes to help with the noise of the rear brake. Mine do that too, I haven't done the fix yet.

Your front brake should be easy enough to adjust at the adjuster next to the handle. There should be a good procedure from the drop io site. It could simply need a good bleed. Brakes get spongy and can stop working at all when air gets in the system.. I'd start there.
