How to install the Magura QM 44 adapter

The adapter bolts between the frame and caliper. First remove the existing caliper. Place the adapter on the frame's Postmount mount – the marking indicates the correct orientation. Screw the caliper onto the adapter. Use a torque wrench (tightening torque per manufacturer specification). After installation, the brake must be bled and adjusted.
