When brake pads become worn out, the caliper which is holding the brake pads, moves further inwards towards the rotor. To compensate for this, the piston from the caliper emerges, making it difficult to remove and replace the brake pad. This 2-in-1 brake caliper rewind tool helps to revert the position of the caliper and the piston back to its original position so that the brake pads can be changed more easily. The tool is suitable for most European and Japanese vehicles and comes with two adaptors. Before purchasing, please check the vehicle's documentation to see whether the tool is compatible
