Brake chatters

2003 mitsubishi galant, 4 cyl, 120,000 mi,

the rt front wheel shudders when braking from high speed, is it possible that it's cv joint.
I have a 94 eclipse 4 cyl, new pads ect does the same thing.
In short is the vibration a typical cv problem?
I have also noticed a hum from the drive train recently on the 2003 and a clunk on accelleration on the 94
