why does my BMW X5 G05 (2019-2024) shake when I brake?

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface, and set the parking brake.
• Wear safety glasses and gloves.

2. Remove Wheel

1. Loosen lug nuts with a lug wrench.
2. Use a jack to lift the vehicle and place it securely on jack stands.
3. Completely remove the lug nuts and then the wheel.

3. Inspect and Replace Brake Rotors

1. Check the brake rotors for warping or scoring using a dial indicator.
2. If warped, remove the caliper by unbolting it and hanging it securely using a bungee cord.
3. Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install new rotors, ensuring they are secure and properly seated.
5. Reinstall the caliper over the new rotor.

4. Inspect and Replace Brake Pads

1. Remove the caliper bracket if necessary to access the brake pads.
2. Check the thickness of the brake pads; replace if they are below the manufacturer’s minimum thickness.
3. Install new brake pads into the caliper bracket, ensuring they are oriented correctly.
4. Reattach the caliper over the new pads.

5. Reinstall Wheel

1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts and then lower the vehicle from the jack stands.
3. Once the vehicle is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 80-120 lb-ft).

6. Test Drive

1. Start the vehicle and test the brakes at low speeds to ensure proper operation.
2. Listen for any unusual noises and feel for vibrations during braking.
