Brake caliper for Viper 125-200 cc motorcycles and similar (China, Minsk). The caliper is mounted on the fork and holds the brake pads. When you squeeze the lever, its pistons press the pads against the disc, slowing the wheel.
Replace it if fluid seeps out, the pistons are seized, the pads sit crooked and wear unevenly. After replacement the brake is bled and checked for leaks.
