The Ultimate Space-Saving Solution for Complex Brake Jobs
Struggling to compress the rear brake pistons on European or modern vehicles with integrated parking brakes? This 34mm Multi-Function Wind-Back Adapter Cube is the precise tool you need. Acting as a versatile adapter head, it allows you to rotate and retract caliper pistons using a standard ratchet wrench or breaker bar.
Kit Contents (1 Piece):
  • 1x 34mm Wind-Back Adapter Cube: A robust, multi-sided adapter block featuring various pin configurations on each face.
Key Features:
  • Multi-Functional 3/4-Pin Design: Each face offers different pin setups (typically 2-pin, 3-pin, and 4-pin layouts). This versatility allows a single tool to fit nearly any wind-back brake piston configuration on the market.
  • Standard 34mm (approx. 1.3″) Square Drive: Designed to fit standard 3/4-inch drive ratchet wrenches and torque wrenches. This lets you use your shop’s high-quality tools for smoother, more controlled winding than manual T-handles.
  • Precision Cast Alloy Steel: Forged from high-strength alloy steel with a protective zinc-plated silver finish. The solid block construction ensures maximum torque transmission without slipping or snapping during tight retraction.
  • Compact & Pocket-Sized: Weighing almost nothing and measuring just 34mm x 34mm x 50mm, this adapter is the ultimate space-saver. Keep it in your mechanic’s pants pocket or glovebox for quick access.
  • Wide Compatibility: Ideal for rear brake service on vehicles with integrated handbrakes, such as Volkswagen, Audi, BMW, Mercedes-Benz, Ford, Nissan, Toyota, and many others.
Applications:
Essential for professional auto repair shops and advanced DIYers servicing rear disc brakes. It is the key adapter required for safely resetting brake pistons that require a clockwise rotation to retract.
