Laser Tool 8654 Caliper Wind Back 5 Point Spline 3/8"D Socket 

Late model VW group vehicles fitted with electronic park brakes use an electronic solenoid to apply the brakes through the caliper. 
When there is an issue with the solenoid, meaning that it will need to be replaced, the Laser 8654 socket is required to wind the caliper back and align it for fitting the new solenoid. 

Applications include: 
Volkswagen Golf Mk VIII.
Brake calipers with electronic EPB solenoids.
3/8"D 5 point spline socket.
Equivalent to OEM T10621.
Use in accordance with OEM instructions
