Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
Gently lift the caliper off the rotor and support it with a bungee cord or similar.
Take out the old brake pads from the caliper bracket and inspect for wear.
If worn below 3mm, replace with new pads (ensure they are compatible with the X5 G05).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or warping. Use a micrometer to measure rotor thickness.
If damaged, remove the rotor by unscrewing the rotor retaining screws and gently prying it off.
Install new rotors, ensuring they are clean and free of debris. Torque the retaining screws to the manufacturer’s specifications.

5. Reassemble Braking Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the specified torque settings.
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle from the jack stands.
Fully tighten the lug nuts in a crisscross pattern to the recommended torque.
Refill brake fluid if necessary and bleed the brake system to remove any air bubbles.
