You have two things that MUST be taken care of on a regular basis. One is to completely FLUSH the brake fluid every two years. This is not bleeding the brake system. This means running almost three quarts of brake fluid through your system to completely change the fluid.
The second thing that needs to be done is that the caliper brake disc slides need to be lubricated so that the calipers slide freely. If this is done every two years, your brakes will be fine for years to come.
Think of it as cheap insurance for your own safety and piece of mind.
