7. Operating Instructions

Follow these steps to effectively compress brake caliper pistons using the OEMTOOLS 25265 Disc Brake Pad Spreader:

1. Prepare the Vehicle: Safely lift and support the vehicle. Remove the wheel and the brake caliper from its mounting bracket, following your vehicle's service manual.
2. Position the Tool: With the old brake pad still in place (this helps protect the piston face), position the backing plate of the spreader against the caliper wall. The threaded end with the knob should be aligned with the brake pad and piston.


Figure 3: Accessing Tight Spaces. The compact design allows the tool to operate in confined areas.

3. Compress the Piston: Twist the green knob clockwise to extend the threaded shaft. This will press the brake pad against the piston, gradually retracting it into the caliper bore. Continue turning until the piston is fully retracted.

4. Release and Remove: Once the piston is fully retracted, turn the knob counter-clockwise to disengage the tool. Remove the old brake pad and the spreader.
5. Install New Pads: Install the new brake pads and reassemble the caliper according to your vehicle's service manual.
6. Repeat for Multiple Pistons: If your caliper has multiple pistons, repeat the compression process for each piston as needed.

8. Maintenance

Proper maintenance ensures the longevity and reliable performance of your OEMTOOLS 25265 Disc Brake Pad Spreader.

• Cleaning: After each use, wipe the tool clean with a cloth to remove brake dust, grease, and other contaminants.
• Lubrication: Periodically apply a light coat of grease or oil to the threaded shaft to ensure smooth operation and prevent corrosion.
• Storage: Store the tool in a dry, clean environment to prevent rust and damage.

9. Troubleshooting

If you encounter issues while using the Disc Brake Pad Spreader, consider the following:

• Piston not retracting: Ensure the tool is properly seated against the brake pad and caliper. Check for any obstructions or seized pistons. If a piston is seized, further diagnosis and repair of the caliper may be necessary.
• Difficulty turning the knob: The threads may be dry or dirty. Clean and lubricate the threaded shaft. If resistance persists, inspect for damage to the threads or the knob.
• Tool bending or deforming: This tool is designed for standard brake caliper piston compression. Excessive force or improper application can cause damage. Ensure the tool is correctly aligned and not subjected to forces beyond its intended use.
