Description

A Compact Tool for Brake Piston Wind-Back

Make room for replacement brake pads with a compact, multi-sided piston tool. Designed for compatible rear brake calipers with screw-in pistons, this cube connects to your existing 3/8-inch square-drive hand tools.

Multi-Sided Design 3/8" Square Drive Compact Metal Tool
Check compatibility before ordering: The tool's pins must match the recesses in your brake piston. It is not a universal fit for every vehicle or caliper design.

Rotate & Retract Compatible Pistons

Some rear brake pistons need to be rotated while inward pressure is applied during pad replacement. This cube engages the matching piston recesses to help carry out that wind-back action.

Use the correct face and follow your vehicle manufacturer's service procedure for rotation direction and piston retraction. Do not force a piston that resists movement.

Multiple Pin Patterns in One Cube

Different faces provide different pin arrangements, giving you several options in one compact tool. Select the face whose pin spacing and shape match your piston.

Check that the pins seat fully in the recesses before applying pressure. Vehicle make or body style alone does not confirm a suitable fit.

Compact Metal Construction

The metal body combines several engagement patterns in a small, easy-to-store shape. Keep it alongside your brake service tools without taking up the space of a larger kit.

Before each use, check the tool for worn pins, cracks, or other damage that could affect engagement.

Works with Your 3/8-Inch Drive Tools

Connect the cube to a 3/8-inch square-drive ratchet and a suitable extension for access. The compact design lets you use familiar hand tools while engaging a compatible piston face.

Tool head only: Ratchet, extension, and other brake service equipment are not included.

Choose by Piston Design, Not Just Vehicle Type

This tool is intended for compatible screw-in brake pistons. Check your caliper's retraction method, piston recess pattern, and working clearance before ordering.

  • Match the recesses: Pin shape and spacing must suit your piston.
  • Confirm the service method: This cube is not a general-purpose press for every brake caliper.
  • Electronic parking brakes: Follow the vehicle's required service-mode procedure. This tool does not activate service mode.

Frequently Asked Questions

Will it fit my vehicle?
Fit depends on the caliper design and piston recess pattern. Confirm that your piston uses a wind-back procedure and that one of the cube's pin arrangements matches. It does not fit every vehicle.
What else do I need?
You will need your own 3/8-inch square-drive ratchet, a suitable extension, and the other equipment specified by your vehicle's brake service procedure. This listing includes the cube tool only.
Can I use it on front calipers or electronic parking brakes?
This cube is intended for compatible screw-in pistons, rather than ordinary push-back pistons. For electronic parking brakes, follow the manufacturer's service-mode and retraction instructions first. The cube does not replace any required diagnostic or service equipment.
