Brake Caliper Piston Wind-Back Tool Set Rockforce RF-907B2, left-hand, 6 pieces

Rockforce RF-907B2 is a left-hand brake caliper piston wind-back tool set consisting of six pieces designed for controlled retraction and rotation of brake caliper pistons during pad replacement and caliper servicing. The kit combines a spindle/handle mechanism with a selection of adapters to fit a variety of caliper types. Using the set helps align and compress pistons evenly, facilitating pad installation and reducing the risk of piston or caliper damage during maintenance.

Advantages

The Rockforce RF-907B2 set provides a mechanical, left-hand rotation solution that enables precise piston retraction without relying on improvised tools. The included adapters allow compatibility with multiple piston face geometries, while the spindle and handle assembly give controlled torque and smooth operation. The compact, six-piece configuration is convenient to carry and store, and the tool’s design minimizes the chance of piston misalignment or seal damage during wind-back.

Suitable for

• Retraction and rotation of brake caliper pistons on passenger cars
• Brake pad replacement and caliper servicing
• Workshops and DIY vehicle maintenance
• Situations where left-hand (counterclockwise) piston rotation is required

Key specifications

• Tool type: left-hand brake caliper piston wind-back set
• Number of pieces: 6
• Includes: spindle/handle mechanism and multiple adapters for different piston faces
• Operation: mechanical wind-back with threaded spindle for controlled retraction
• Compatibility: designed for a range of vehicle caliper designs requiring left-hand rotation
• Material: durable metal construction suitable for workshop use

How to use

Secure the vehicle and remove the wheel and brake caliper according to the vehicle manufacturer’s instructions. Select the adapter that matches the piston face and attach it to the spindle/handle assembly. Position the adapter against the piston and engage the spindle. Turn the handle in the left-hand (counterclockwise) direction to rotate and gradually retract the piston into the caliper housing. Continue until there is enough clearance to fit the new brake pads. After installation, verify piston alignment and reassemble the brake components, then test the brake operation at low speed before regular use.

Usage recommendations

Use the Rockforce RF-907B2 set on clean, inspected calipers and follow vehicle-specific service guidelines. Apply steady, even pressure when winding back pistons; avoid sudden force. If calipers exhibit corrosion or seized pistons, inspect and service or replace components as necessary before using the tool. Keep adapters and spindle clean and lightly lubricated to ensure smooth operation and longevity.
