Important Safety Warnings – Read Before Use

This tool uses an (electric drill) and spins at high speed. Improper use can damage your bicycle, wheel, rotor, pads, or cause injury.

Never apply excessive pressure — pushing too hard can bend the rotor, damage the wheel, or harm the bike.

Wear safety glasses, dust mask, and gloves. Work in a well-ventilated area.

Do not use cracked, severely warped, or damaged rotors.

This is a maintenance tool only — not a replacement for professional brake service.

Test brakes thoroughly in a safe area after use.

What You Need

Discy-Pro tool

 Variable-speed electric drill or Impact driver

Replaceable DiscY-Pads

Brake cleaner or isopropyl alcohol

Clean cloths

Step-by-Step Instructions

1. Prepare the Rotor 

   - Clean the disc rotor thoroughly with brake cleaner or isopropyl alcohol to remove dirt, grease, and old glaze.  

   - **Dry the rotor completely** before starting. This reduces contamination of the pads and ensures a better finish.

2. Install the DiscY-Pads

   - Remove the rubber stopper from the tool.  

   - Insert the replaceable abrasive pads into the slots on both sides. Ensure they are seated correctly.  

   - Re-insert the rubber stopper to secure the pads.

3. Position the Tool on the Bike  

   - Place the bike on a stable stand.  

   - Open the Discy-Pro and position it over the disc rotor so the pads contact **both sides** evenly.  

   - **Make sure the tool is perfectly aligned** with the disc rotor (centered and square). Misalignment can cause uneven surfacing or damage.  

   - Use the **adjustable tension/pressure control** to set a light pressure. Always start with the lowest setting.

4. Surfacing Process 

   - Secure the tool’s drive shaft firmly in the drill chuck.  

   - Hold the tool steady with both hands.  

   - **Start the drill at a slow speed** to gently get the wheel spinning.  

   - Once the wheel is rotating smoothly, gradually increase to a **faster (medium) speed**.  

   - Apply **light, consistent pressure** only. Move the tool slightly in and out across the rotor surface for an even finish.  

   - Surfacing time: 10–30 seconds per pass. Stop and check progress regularly. Do not overdo it.

5. Clean Up and Inspect 

   - Stop the drill and remove the tool.  

   - Wipe the rotor clean of all dust.  

   - Spin the wheel by hand and visually inspect the fresh surface.  

   - Repeat if needed with light pressure.

6. Test the Brakes  

   - Reassemble anything you moved.  

   - Bed in the brakes with several gentle stops from low speed.  

   - Test braking carefully before normal riding. Expect improved performance and reduced noise.

Tips for Best Results

- Clean and dry rotor = cleaner pads and better finish.  

- Light pressure and proper alignment give the best “serviced” look.  

- Replace pads when worn for consistent performance.  

- Dual-sided design surfaces both sides at once — very efficient.

Troubleshooting

- Uneven surface → Re-align tool and ensure even pressure.  

- Wheel stops or vibrates → Reduce pressure and slow the drill.  

- Excessive dust → Better cleaning before use helps.
