Follow these steps carefully
Confirm a 2015–2020 F82 coupe or F83 convertible M4; the video covers exactly those cars. Order pads and rotors listed for the F82/F83 M4, not the standard 4 Series. Check for M carbon-ceramics; their pad and bedding procedure differs completely.
Break the front wheel bolts loose with the wheels loaded on level ground. Raise the front with a floor jack at the central jacking point and set it on jack stands. Never work under a car on a jack alone.
Remove the wheel bolts and both front wheels to expose the M calipers. Photograph the wear sensor routing and anti-rattle clips before touching anything. Check the rotor faces for deep scoring or a lip, confirming replacement rather than pads alone.
Trace the wear sensor wire from the inner pad to its wheel-well connector and unplug it carefully; a damaged sensor wire triggers a permanent brake warning. If the sensor has worn through to the contact, replace it with the pads.
Remove the two guide bolts and lift the M caliper off the carrier; hang it from a bungee or wire, never by the brake hose. Slide the pads out and check for uneven wear. Wire-brush bracket seats before fitting hardware.
Uneven pad wear on one side almost always means a sticking guide pin, not a bad pad — if one pad is tapered, I pull the pins and make sure they slide freely before the new pads go in.
Remove the rotor retaining screw and pull the old rotor off the hub, using penetrating oil and light taps if seized by corrosion. Wire-brush the hub face so the new rotor sits flat; a dirty hub face causes pedal pulsation.
Fit the new rotor onto the clean hub and reinstall the retaining screw snugly. Install the anti-rattle hardware and slide the pads in, wear sensor pad positioned correctly. Refit the caliper and torque the guide bolts to spec.
Plug the new or undamaged wear sensor into its connector and re-clip the wire along it. Refit the wheels, torque the bolts in a star pattern to spec, and pump the pedal several times before driving to seat the pads.
Bed the pads: moderate stops from 60 km/h to 20 km/h without fully halting, cooling between runs. Avoid hard stops for the first 300 km to prevent glazing. Road test and confirm no pull, vibration, or warning light.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
