Every car has brakes that wear out and need to be adjusted to maintain stopping distances and braking power. Some cars still have rear drum brakes and front disc brakes. The rear drum brakes can be adjusted automatically in all vehicles. Most newer vehicles will have disc brakes on the front and rear and can't be adjusted by the method specified.
Take car to open lot and shift gear selector into reverse. Check the vehicle manual if you are not sure if the car is equipped with drum brakes in the rear.
Drive vehicle backward and press brake pedal on and off slowly as you are going backwards. If no change is noticed apply quick braking force during backing up in reverse.
Continue hitting brake pedal 8 to 10 times and each time the automatic adjuster will move brake shoes outward and adjust for brake wear. If still no difference is noticed brakes may be worn out beyond adjustments.
