4. Tatūnga
Before using the tool kit, ensure your vehicle is properly prepared for brake service. This involves:
- Tuhia te waka ki runga i te mata papatahi ka uru ki te waahi waka.
- Loosen the lug nuts on the wheel(s) to be serviced.
- Raise the vehicle using a suitable jack and secure it with jack stands.
- Remove the wheel(s).
- Remove the brake caliper from its mounting bracket, typically by unbolting the guide pins. Do not disconnect the brake hose unless absolutely necessary. Support the caliper to prevent strain on the brake hose.
- Tangohia nga papa pakaru tawhito.
Identify the correct adapter plate from the kit that matches the piston face of your vehicle's brake caliper. The main rewind tool is designed to push and/or rotate the piston back into the caliper bore.

5. Nga Tohutohu Whakahaere
This kit is designed to retract brake caliper pistons, which may require both pushing and rotating, depending on the vehicle's brake system (e.g., some rear calipers with integrated parking brakes). Always refer to your vehicle's specific service manual for the correct procedure.
5.1. Hototahi
The various adapter plates in the YT-0681 kit ensure compatibility with a wide range of vehicle makes and models. The following table provides a general guide for some common applications. Always verify the correct adapter for your specific vehicle and caliper type.

5.2. Piston Rewind Procedure
- Select the appropriate adapter plate that fits the grooves or indentations on your brake caliper piston.
- Attach the selected adapter plate to the main rewind tool.
- Position the rewind tool with the adapter plate against the piston face and the reaction plate against the caliper body.
- Slowly turn the handle of the rewind tool. For pistons that require rotation, ensure the adapter engages the piston's features. Turn the handle clockwise for right-hand threaded pistons and counter-clockwise for left-hand threaded pistons (common on some rear calipers).
- Continue turning until the piston is fully retracted into the caliper bore, flush with the caliper housing. Do not force the piston beyond its natural stopping point.
- Once the piston is retracted, carefully remove the rewind tool.
- Tāutahia ngā papa pēki hou, ka huihuia anō te caliper pēki kia rite ki te pukapuka ratonga a tō waka.
- After reassembly, pump the brake pedal several times to seat the new pads and restore pedal pressure before driving. Check the brake fluid level.
6. Tiaki
Proper maintenance will extend the life of your YATO YT-0681 tool kit:
- After each use, clean all components with a clean cloth to remove brake dust, grease, and dirt.
- Apply a light coat of machine oil to the threaded rod of the main rewind tool to prevent corrosion and ensure smooth operation.
- Store the tools in their original durable case in a dry environment to protect them from moisture and damage.
- Regularly inspect the tools for any signs of wear, damage, or deformation. Replace any damaged components immediately.
7. Te Raru
If you encounter issues while using the YT-0681 kit, consider the following:
- Tool not fitting the piston: Ensure you have selected the correct adapter plate for your specific caliper piston. Some pistons have unique patterns.
- Difficulty turning the rewind tool:
- Verify that the adapter plate is correctly seated in the piston's grooves.
- Confirm the piston requires rotation (e.g., rear calipers with integrated parking brakes) and you are turning in the correct direction (clockwise for right-hand, counter-clockwise for left-hand).
- Check for any obstructions or corrosion within the caliper bore.
- Ensure the brake fluid reservoir cap is loosened or removed to allow fluid displacement.
- If the tool's bar bends under normal operating force, it may indicate excessive resistance from the caliper piston or a manufacturing defect. Discontinue use and inspect the caliper for issues or contact Yato support.
- Piston not retracting fully: Ensure the brake fluid reservoir is not overfilled, preventing the piston from fully retracting.
