Solution

1. Preparation

Gather tools and parts needed for the brake pad replacement.
Safety gear: gloves and safety glasses.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the front or rear of the BMW X5, depending on which brake pads you will be replacing.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to gain access to the brake assembly.

4. Remove the Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor. Do not let it dangle on the brake line; use a bungee cord or similar to support it.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Compare new brake pads with old pads to ensure they are the correct size.
Install the new brake pads into the caliper bracket.

6. Reinstall the Brake Caliper

Compress the caliper piston using a brake caliper tool to make room for the new pads.
Position the caliper back over the new brake pads and secure it by tightening the mounting bolts to the manufacturer's specified torque (usually around 25-30 Nm, but confirm with the service manual).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the proper torque (usually around 120 Nm).

8. Final Checks

Pump the brake pedal several times to ensure the brake pads seat properly.
Check brake fluid level and add fluid if necessary.
