Caliper piston tool

A method of using a caliper piston tool comprising:

• inserting a first paddle and a second paddle between a pair of opposing caliper pistons, the first paddle fixed in position on a first handle, the first handle including a guide track;
• and
• compressing the first handle and a second handle together, the second handle to pivot about the first handle at a handle joint, and the second handle including a drive finger fixed in position on the second handle, wherein the second paddle includes:
• a drive socket, wherein the drive finger is engaged within the drive socket, and
• a guide follower constrained to linear motion along the guide track, wherein rotation of the drive finger about the handle joint drives a linear motion of the guide follower along the guide track and separation of the first paddle and the second paddle.

A caliper piston tool comprising:

• a first handle including a guide track and a first paddle fixed in position as a flush front face of the caliper piston tool;
• a second handle to pivot about the first handle at a handle joint, the second handle including a drive finger fixed in position on the second handle;
• and
• a second paddle including:
• a drive socket, wherein the drive finger is engaged within the drive socket, and
• a guide follower constrained to linear motion along the guide track, wherein rotation of the drive finger about the handle joint drives a linear motion of the guide follower along the guide track, and
• a friction adjuster including aligned apertures through the first handle and the second paddle and a fastener extending therethrough, the friction adjuster to mechanically set a tolerance between the guide track and the guide follower.
