brakes or break pads

have them checked at a shop. 3 years is a long time. Roy

It depends on how much braking you do and how hard. Does it sound like metal on metal. Most brake pads have little metal tabs on them that dig into your rotors when they get too low. Around 1/8". Pull your tire off and use a flash light to look down at your brake pads to see how thin they are. If you have no clue what to look for then find a shop that will check pads for free.
