Got some powerstop rotors installed recently and I have a weird scenario happening that makes no sense to me.

When braking and under any type of elevation change (bump, unevenness in the road) I get a pulsing almost grinding sound out of the left front wheel. Does not happen under regular braking or hard braking.

To make things odder, if I go in my driveway there's a big bump and I've tried to make it reproduce it there but it won't do it. Guess because the car is barely moving.

Any ideas? This one has me puzzled?

Going to bring it back to Chevy once this COVID-19 thing is over since they installed them but it's driving my crazy right now.
