Pontiac Vibe blumping sound from right rear wheel when stopping after brake and drum replacement on Pontiac Vibe

Some Pontiac Vibe owners report experiencing a thumping sound from the right rear wheel after replacing the rear drum brakes. This noise may be caused by a warped drum, as evidenced by the sound shifting to the opposite side when the drums are swapped. Additionally, a brake wear indicator could be contributing to the noise, which can be further examined by listening closely while someone presses on the door panels. Other potential issues include problems with brake pads, rotors, or calipers, each presenting different symptoms. Furthermore, some owners may encounter a stuck caliper that fails to release the brake pads, leading to noise during braking. To effectively resolve the thumping sound, it is crucial to inspect the drums, brake components, and calipers for any signs of damage or malfunction.
