2011 Tacoma Front End Slight Bouncing On Braking

When I first start my Tacoma and ease into a stop from 35 mph on asphalt, the front right wheel is mini-bouncing (not shimmying), like I'm driving over several small ridges in a row as I ease to a stop. On other street surfaces or after I've been driving for a while it's greatly reduced or not present at all.

Anyone know what kind of problem this is? Thanks.

 

possible wheel balance issues. id start with that unless you suspect a rotor maybe warped. check the lugs for tightness too

 

I had this issue on a company car once, where it vibrated only at certain speeds & while breaking. Turned out that under the hubcap only one lug nut was holding the wheel on! Check that first.
