Removing and installing brake pads (PR 1LF): Audi Q7

🧭 Before you start

Remove the wheels, unplug the wear indicator and lift the wire from under the dust cap. Remove the bolt, press the retaining spring in, pull the retaining pin and take out the spring and pads. Check the disc, draw off some brake fluid and press the pistons back. Fit the sensors to the new pads, insert pads and spring, route the wire under the tab, push the pin to its stop, tighten the bolt, reconnect and seat the pads with the pedal.
