This Magura QM40 Caliper Adapter Bracket allows you to use a 180mm rotor on a 160mm direct - mount fork. For the rear brake, it enables the use of a 160mm rotor on a 140mm direct - mount or an 180mm rotor on a 160mm direct - mount, enhancing your braking system's flexibility.

To use this Magura QM40 Caliper Adapter Bracket, first, make sure your fork or rear brake is a direct - mount type. For the fork, attach the bracket and then mount the 180mm rotor. For the rear brake, if you're using a 160mm rotor on a 140mm direct - mount or an 180mm rotor on a 160mm direct - mount, just install the bracket and then the rotor. When handling the bracket, be careful not to scratch or damage it. After installation, check for any loose parts and tighten them if necessary. To maintain it, clean the bracket regularly with a dry cloth to prevent dirt build - up and ensure smooth operation.
