8-97191-109-0 Rear Brake Shoes And Drums
some signs brake shoes don't work as well as they should be:
Squealing or rubbing noises
Pulling to one side during braking
Reduced braking power
Ineffective parking brake
Why you should inspect and replace brake shoes
Worn shoes can dramatically reduce your braking system's stopping power and lead to dangerous increased stopping distances. Ignoring worn shoes can also lead to more expensive repairs, such as grooved brake drums that will also have to be replaced. Worn rear shoes will also accelerate front disc pad wear, causing a low brake pedal and delayed braking response.
Brake shoes last an average of 30,000 to 70,000 miles, but you should check them after each oil change to be on the safe side.
