Troubleshooting car problems of brake pedal vibration during braking
Vibration of brake pedal that can be felt coming from rear end of car when braking only mean one thing, the problem is related to your car rear brakes. This case is a result of misalignment between brake shoes and drums (car disc brakes and brake pads in case your car have a rear disc brakes), the brakes shoes and brake drums are not in even contact with each other thus resulted into vibration during application of brake. Misalignment is most likely cause by warped brake drums. However, it is possible that the rear brake drums has no problem but rather the rear wheel bearing are loose or worn out and this cause misalignment between the rear brake drums and rear brake shoes.
