had new napa premium drums installed yesterday. took car home from shop and passanger side in the rea makes a hard thump thump thump when brake is applied? called shop said that it must be a out of round and or warped drum and its very common for any brand drum. I dont understand how an out of round or warped drum would make such a hard thump this isnt a shaking sensation you feel its a hard thump or knock when the brake is applied. any ideas? i know before they did the drumd the shoes were still very very good and i had no braking issues at all anywhere on car.
