Draper Expert Brake Caliper Piston Wind-Back Kit (18 Piece)

Whether you're a professional mechanic or a dedicated DIY enthusiast, the Draper Expert Brake Caliper Piston Wind-Back Kit (CWBT18B) gives you everything needed to return brake caliper pistons cleanly and efficiently – creating the clearance required for new brake pad installation across most vehicles, all from a single compact and well-equipped kit.

Left and Right Handed Winders for Full Compatibility

Different vehicle manufacturers use different piston thread directions, making dual-direction capability essential in any serious brake wind-back kit. The CWBT18B includes both left and right handed winders, each fitted with twin drive pins and a magnetic retainer for secure, positive engagement with the piston face. The magnetic retainer holds the winder plate firmly in position during use, preventing it from dropping away and keeping the tool correctly located throughout the wind-back process.

• 2 x Left-handed winders with twin drive pins and magnetic retainer
• 1 x Right-handed winder with twin drive pins and magnetic retainer

13 Winder Plates for Extensive Vehicle Coverage

The breadth of the CWBT18B's compatibility comes from its 13 winder plates, which cover a wide range of caliper piston profiles found across passenger cars, SUVs, and light commercial vehicles. Having the correct plate for each piston profile ensures the wind-back force is applied evenly and correctly, protecting the piston face from damage and delivering a professional result every time.

Universal Pressure Plates for Added Versatility

Complementing the winder plates are two universal pressure plates – a circular piston pressure plate and a universal caliper pressure plate – which further extend the kit's compatibility across different piston and caliper configurations. These plates distribute compression force evenly, making them particularly useful on front caliper pistons that compress rather than wind back.

Twin Pin Winder with 3/8" Square Drive

The kit also includes a twin pin winder with a 3/8" square drive facility, allowing it to be used with a standard ratchet or driver for faster, more controlled wind-back. This addition makes the CWBT18B faster and more ergonomic to use on vehicles where a ratchet-driven approach is preferred over a manual T-bar style tool.

Corrosion Resistant Finish for Long Service Life

All components feature a corrosion resistant finish, protecting the kit against the moisture, brake fluid, and grime that inevitably accumulate in brake work environments. This finish ensures the winders and plates remain in reliable working condition long after the initial purchase.

Supplied in a Blow-Mould Carry Case

All 18 components are housed in a blow-moulded plastic carry case with display sleeve, keeping every winder, plate, and adaptor neatly organised and fully protected between uses. The case makes it easy to identify and retrieve the right component quickly, reducing time spent searching for the correct piece mid-job.
