Whenever i brake, hard or soft, it feels like theres a steady bumping. Not a destructive noise, but just a bump.. as if theres a part of the tire where the brake catches every time it passes over it and just makes a little bump.

Any ideas as to the problem, and what i could do to fix it?

 

Sounds like to me your rotors are warped. Mine are doing the same thing. I am working on replacing mine because they are below 15%. A fix would be to take off the rotors up front and take them to a place the will "turn" them for you.

 

screw the turning... they will warp again just as easy... get a set of powerstop cross drilled or slotted rotors & pads you will love them.
