Draper Expert Adjustable 2 and 3 Pin Brake Piston Wind-Back Adaptor

Eliminate the need for multiple fixed-size wind-back adaptors with the Draper Expert Adjustable 2 and 3 Pin Brake Piston Wind-Back Adaptor (ABWA). This innovative single tool adjusts to fit a wide range of caliper piston pin configurations across both conventional and electronic parking brake systems – making it one of the most versatile and practical additions to any brake servicing toolkit.

Adjustable Rotating Bezel for a Perfect Fit Every Time

The defining feature of the ABWA is its rotating centre bezel, which simultaneously adjusts both sides of the tool to the correct pin spacing for the caliper piston being serviced. Rather than carrying a range of fixed adaptors and hunting for the right size mid-job, simply rotate the bezel until the pins align with the piston – fast, intuitive, and reliable. This single adjustment mechanism delivers a precise, secure fit across the full size range, ensuring the wind-back force is applied correctly and evenly to the piston face.

2-Pin and 3-Pin Capability in One Tool

Many brake caliper pistons use either a 2-pin or 3-pin drive configuration, and the ABWA handles both with equal ease. Simply select the appropriate side of the tool for the job in hand:

• 3-pin side: adjustable from 20–30mm – for the compact pin spacings found on many smaller caliper pistons
• 2-pin side: adjustable from 22–35mm – covering the wider range of two-pin caliper configurations

Together, these ranges span the vast majority of brake caliper piston types found on modern passenger cars, SUVs, and light commercial vehicles.

Compatible with All 3/8" Drive Wind-Back Tools

The ABWA features a standard 3/8" square drive connection, making it immediately compatible with all wind-back tools, ratchets, and drivers that use this common drive size – including the Draper Expert CWBT18B and CWBT39B kits. No special tools or adaptors are needed; simply connect and work.

Electronic Parking Brake (EPB) Compatible

As electronic parking brake systems become increasingly common across modern vehicle platforms, having EPB-compatible tooling is essential. The ABWA is fully compatible with electronic parking brake systems when used in conjunction with appropriate EPB reset equipment, ensuring it remains relevant and useful as the vehicle parc continues to evolve towards more sophisticated braking systems.

Built for a Wide Range of Vehicles

Whether you're servicing a common family car, a performance vehicle, or a modern SUV with an electronic handbrake, the ABWA's adjustable design and broad size range make it a genuinely universal solution for caliper piston wind-back across a wide spectrum of vehicle makes and models.
