1. The 360-degree ratchet swing can be used at any angle, which is more convenient. 2. Centralized distribution of power to prevent misalignment of pistons. 3. It can be used for dual-piston and four-piston fixed calipers, as well as single-piston and double-piston floating calipers. 4. The centrally located ratchet evenly distributes the force in a parallel manner to avoid misalignment of the piston. 5. The ratchet technology can provide a complete 360-degree swing, so that the spreader can be placed in any position. 6. The extended reversing lever makes the operation from unfolding to retracting easy.
