360-Degree Ratcheting & Switch: The ratchet technology of this Brake Caliper Tool provides a 360-degree swing, allowing you to keep the compression plates in place while moving the handle back and forth to spread or retract the plates

4 Caliper Hooks: The caliper piston compressor tool includes 4 brake caliper hooks for hanging the brake caliper, brake hoses, and other parts, facilitating easy inspection of other car components during car brake repair

Apply pressure to both spreading plates to start the ratchet; squeeze them for the first few swings until they fit into the calipers, then continue swinging
