GLS550 Brakes sporadically “pulsate” like warped rotors

Sometimes my brakes feel like they are badly warped when coming to a stop and other times they feel fine. The brakes have been inspected and rotors look clean.

Has anyone else experienced/remedied this?

Uneven pad deposits. Two ways to fix it - a few 90 to 5mph hard braking runs, or getting the rotors either sanded or resurfaced somehow.

Any recommendations on better-than-oem aftermarket rotors?

I installed these Zimmerman rotors last fall and they've been great - https://www.fcpeuro.com/products/mer...mbo-1664210912

I haven't done the rears yet, but I will this fall. I did the fronts last year because they got warped after a long road trip.
