Laser Tools 3940 Brake Caliper Rewind Tool For BMW MINI

Laser Tools 3940 Brake Caliper Rewind Tool - BMW MINI

The Laser Tools 3940 is a highly specialized brake piston rewind tool specifically engineered for the rear calipers of BMW MINI models (R50, R52, R53, R56). Many modern rear calipers incorporate the handbrake mechanism into the piston, requiring the piston to be rotated as it is pushed back during a pad change. Attempting to force these pistons back with a standard G-clamp will cause permanent internal damage to the self-adjusting mechanism. This tool features a precision-machined 2-pin drive face that perfectly matches the MINI's piston profile. The heavy-duty screw thread provides the controlled mechanical advantage needed to retract the piston smoothly and safely. Forged for durability and featuring a comfortable T-handle, this tool is essential for any technician or MINI owner performing rear brake maintenance, ensuring the handbrake remains functional and the caliper remains undamaged.

• MINI Specific: Designed for the unique rear caliper piston profile of the BMW MINI range.
• Mechanical Precision: Combines rotation and pressure to safely reset the handbrake mechanism.
• Damage Prevention: Protects the sensitive internal self-adjusting gears from force damage.
• Hardened Steel Construction: Built to withstand the high torque required for seized pistons.
