Your security depends on the up-keep of your brake system, so you better get them checked regularly!
Be attentive to the first signs of wear:
stopping distance, vibrations under feet when pressing the brake pedal, unresponsive brake pedal or car swerving to the side.
To maintain effective and safe brakes, make sure to follow the maintenance program, and to change the brake fluid every 120,000km or every four years. Make sure to dust your drum breaks every 60,000km.
