AC pump + brake advice

Alright… first of all, my car (s14) was hoisted up and i noticed my AC pump had oil all over it. And my ac doesnt work. So im assuming i need a new AC pump, but whats labour like in replacing it.

Can i do it myself or should i take it to a shop?

Next question is brakes, i need to replace them and i got quoted 170 for pads and rotors on all 4 corners. Good price or no? Im just looking for something average and these ones were good i was told, however i didnt get the name brand unfortunately…

I was also wondering if anyone has a hookup for pads and rotors that might be cheaper.

For the AC, you need to get a shop to do the work. Its illegal to do it yourself unless you have an AC license.
