There are a few reasons for squeaky brakes. The reason I have them is because I drive as tight-fisted as possible and brake with plenty of time, slowly and progressively. This causes the brake pads to "glaze" and thus not have the same rough-on brake discs as a car that slams the brakes on hard and fast.
I believe the remedy to my solution is to take the brake pads off and scrub them with a wire brush and then use a de-glazing solution to make them not shiny. Not sure if this happens with rear drum brakes though.
Perhaps someone else has more relevant information for your situation. |
