Removing the rotor from a bike wheel primarily involves unscrewing the bolts or lockring securing it to the hub and then lifting it off.
Step-by-Step Rotor Removal
To remove a disc brake rotor from your bike wheel, you will typically need the appropriate tool for the fasteners used. Rotors are commonly attached using either 6 bolts or a centerlock ring.
Here are the general steps:
- Prepare the Wheel: Remove the wheel from your bike. This makes it easier to access the rotor.
- Identify Fasteners: Determine if your rotor is attached with 6 bolts (usually Torx T25 or Allen bolts) or a centerlock ring.
- Remove Fasteners:
- For 6-Bolt Rotors: Use the correct size Torx or Allen wrench. Carefully engage your wrench all the way into the fastener as the bolts often have a shallow recess. Loosen each bolt a turn or two, working in a cross pattern (like tightening lug nuts on a car wheel) to evenly release tension. Once all bolts are loose, fully unscrew and remove them. Keep track of the bolts as you remove them.
- For Centerlock Rotors: You will need a specific centerlock tool, which is often the same tool used for external bearing bottom brackets or cassette lockrings. Engage the tool with the lockring and turn counter-clockwise to loosen and remove it.
- Remove the Rotor: After all the bolts are safely out (or the centerlock ring is removed), the rotor should lift straight off the hub. If it's slightly stuck, a gentle wiggle might help, but avoid bending it.
Tools Required:
| Rotor Type | Tool(s) Needed |
|---|---|
| 6-Bolt | Torx T25 or Allen wrench |
| Centerlock | Centerlock tool |
Important Considerations:
- Always use the correct tool size to avoid stripping the bolt heads or damaging the centerlock ring.
- Be cautious when removing fasteners; dropping bolts can cause them to be lost.
- Keep your rotors clean and avoid touching the braking surface with your fingers, as oils can contaminate the pad surface.
Once the rotor is removed, the wheel is ready for whatever maintenance or replacement is needed.
