Brake pads bad?

Bonded shoea seldom seperate.
When you do replace your brake "shoes" not pads, continue to use bonded lining. Do not use riveted shoes.
Also good practice to replace all of the springs and hardware each time. Lots oh heat inside those drum brakes and heaty is what weakens springs and the rest. Hardware is cheap insurance against componenet failure.
