Squeaky (wheels) brakes?

i did find that the ''fingers'' of the pad, are a little wider than the caliper ''slides'' that they ride upon, but i greased this with copper grease..

should i hammer the fingers so they fit tight on the pad?
Yup they hold the pad tight, pry them up with a flat blade screwdriver and hammer them down the top tab so it is tight, that is probably the noise.
