Like all things mechanical - it depends. How severely is it used and driven - what kind of climate or area of the country is it driven in - the quality of the parts it is maintained with - etc.? 20,000 miles seems like an awfully short length of time for brakes. Exterior rust on the calipers and running gear is not a reliable indicator (in itself) as to how well the brakes are operating. Since brakes are one of the most important items on a vehicle - besides steering - I would suggest having your mechanic check them over for a professional evaluation.

You did not list which model Mazda or which engine. However all of these 4 cylinder Mazda engines have a cam belt that should be replaced every 60,000 miles or 10 years whichever comes first. 1.6 Liter 1.8 Liter 2.0 Liter The 2.3 Liter V6 also has a belt that should be replaced at 60,000 miles. The 2.5 Liter V6 has a belt that should be replaced at 105,000 miles. None of these are interference engines but if the belt breaks you will have to have the car towed and you will be stranded.
