ND MX-5 Miata Rear Brake Caliper Rewind Tool

This is a tool for doing rear brake jobs on the ND generation MX-5 Miata. To retract the piston in the rear caliper, you have to rotate the piston clockwise. The piston face has a cross pattern that this tool matches perfectly. This should be better than trying to use a metal tool that could cause damage to the piston/seals. I've modeled this to be used with a 14mm deep socket. You can also use a standard 14mm socket and an extension to clear the caliper interference with a ratchet. Remember to clock the cross pattern correctly as the rear brake pads have a post that align to this geometry. Included the STEP file in case you want to change the socket dimensions for your own use. Printed with 4 outer walls in PLA should be plenty durable.
