Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, wheel chocks, brake cleaner, safety glasses, and gloves.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which brake pads are being replaced.
Secure the vehicle with jack stands and place wheel chocks behind the rear wheels.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to expose the brake assembly.

4. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
Unbolt the caliper using the socket set and carefully slide it off the rotor.
Hang the caliper using a wire or bungee cord to avoid putting strain on the brake line.

5. Remove Old Brake Pads

Slide the old brake pads out of their slots.
Inspect the caliper and rotor for wear or damage.

6. Install New Brake Pads

Parts Required: New brake pads suitable for BMW X3 G01.
Slide the new pads into the caliper bracket, ensuring they are correctly oriented.

7. Reinstall Brake Caliper

Reposition the caliper over the new pads and bolt it back in place using a torque wrench to the manufacturer’s specifications.

8. Reattach the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the specified torque.

9. Final Check

Pump the brake pedal a few times to seat the new pads.
Check brake fluid level and add if necessary.
