Shopping cart brakes slow or render a shopping cart immobile. A brake lever has one end pivotably connected to a clamp that is attached to one end of a vertical member of a shopping cart adjacent to its handle. Two brake cables are enclosed by brake cable housings and have one end connected to the brake lever. A plurality of brake cable supports secures the brake cable housings to the vertical member. Alternatively, the brake cables and brake cable housings can be enclosed by vertical members and a horizontal member. The opposing end of the brake cables is attached to calipers. The calipers have brake pads removably connected to them. A brake lever housing is also connected to the clamp. The brake lever housing is attached to an adjuster barrel and houses a brake lever locking mechanism comprising a locking tab, locking button, slot, and locking button hole.
