Violent shaking in right wheel when braking?

I’m having an issue with violent shaking in my front right wheel when I brake. It started after I changed the pads, but not the rotors. If I brake really hard it’ll smooth out and sometimes it won’t shake like on the highway in traffic, usually only when I brake regularly. Could this be the rotors, or does it seem like a control arm/bushing issue? New inner and outer tie rods, just greased all ball joints and attempted to grease the bushings but they are rock solid. Front end is squeaking bad too over every nook and cranny and it’s coming from the control arm bushings. Sometimes, like tonight, the right wheel will track heavily and feel like it's going to fall off. Thanks in advance.
