Ok I have done park brakes on older volvos. I think my left rear shoe has separated. My R is still under CPO warranty, but dealer is 120 miles away. I want to pull rotors and check it out myself. I think there may be more wrong with it than just the pad separated because it sounds bad when I pull brake lever. My big question is will I be able to get all the pieces put back if it has exploded so I can get it repaired under warranty? Will shoes from a 240 or 740 fit if it is just separated shoes?
