Spin the wheel slowly to find exactly where the rotor rubs against the caliper or looks warped, then slide the notched jaw of the wrench onto the rotor at that spot and apply light, gradual pressure in the opposite direction of the bend. Recheck by spinning the wheel again after each small adjustment, since rotors are thin and respond to very light pressure, so it is easy to overcorrect if you push too hard in one go.

Having notched jaws at both ends of the wrench lets you reach a bent section of the rotor from different angles or positions relative to the wheel and caliper, without needing to remove the wheel to get the right approach. It also means the tool offers slightly different leverage points depending on which end you use.

Rotor truing is a very approachable home job as long as you work in small increments and check your progress often, since a light touch is all that is needed to correct most minor warps. Applying excessive force in one spot is the main way to make a bend worse, so patience is more important than strength when using this tool.

Minor to moderate warps caused by a knock or transport can usually be corrected with this wrench, but a rotor that is severely bent, cracked, or has been dropped hard is safer to replace outright rather than risk a compromised braking surface. Rotors are relatively inexpensive, so when in doubt about the severity of a bend, replacement is the safer route for something as safety-critical as your brakes.

This wrench uses stainless steel construction for the working jaws paired with a rubber-coated grip, giving a comfortable, secure hold while you apply careful, controlled pressure to the rotor. The rubber grip also helps reduce hand fatigue if you are working through several rotors in one session.

Yes, this is a genuine LEBYCLE rotor truing wrench sold through DoGoodCo, built from stainless steel to resist wear over years of use. If your tool arrives damaged or defective, our support team will help arrange a replacement as per store policy.
