QQ3 of Chery adopts front disk & rear drum brake linings--when applying disk brake, the oil pressure will push the brake lining to clamp the brake disk and use the friction generated by their contact to restrain the rotation of tyre so as to realize braking. The disk brake has a good reaction and stability, a good heat elimination capability and convenience in replacement. The drum brake has a drum-type cast iron component called brake drum, which is fixed to the tyre and rotating at the same speed with the tyre.
