light braking vibration- cause?

[Russell]

I replaced my front rotors and pads with ATE oem style rotors and Raybestos QS creamic pads about 10,000 miles ago. Just in the past week or so, I have started to notice a slight vibration when light braking. None on heavy braking? Not sure what to look for? However, I do suspect thrust arms.

FYI, tires were rotated and balanced two weeks ago. I do it every 5,000 miles. Runs smooth with no vibration at any speed. Only on braking.
TIA

just for fun... did it do it before you rotated the tires?
it could be just slightly off and your suspected thrust arms maybe don't help!

I thought about that. Even so, that is possible. even though it is the same shop I always use and they use quality Hunter equip and hand torque the lug bolts to 72 foot lbs which I believe is spec.

Thrust arms do clunk a bit with busted boots. Time to replace regardless.

My car did that exact same thing before i replaced the thrust arm bushings.
