After 120k, brakes were due. It's seemed pretty straightforward, so I installed new rotors, pads, drums & shoes. Now the brakes have a new pulsating problem. I've got the service manual and have taken them off twice since to inspect what I did.
I bought aftermarket (Brembo). Could it be the factory shims on front pads are not needed with the new pads. It might be a long shot, but any advice is appreciated at this point. Thank you.
