how can I fix my BMW X5 F15 (2014-2019) that’s shaking when I brake

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the battery for safety.

2. Wheel Removal

• Tools Required: Socket set, torque wrench, wheel chocks.
• Loosen the lug nuts slightly while the vehicle is on the ground (do not remove them yet).
• 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 Components

• Brake Rotors:

  • Check for warping using a runout gauge.
  • If warped beyond specifications, remove the rotor by unbolting it from the hub.
  • Install new rotors, ensuring they are properly seated and torqued to manufacturer specifications (check service manual for torque values).

• Brake Pads:

  • Remove the caliper by unbolting it from the bracket.
  • Inspect the brake pads for wear; replace if they are worn unevenly or below the minimum thickness.
  • Lubricate caliper pins and install new brake pads, ensuring they fit snugly.

4. Reassemble and Reinstall Wheel

• Reattach the caliper and ensure it is properly bolted.
• Place the wheel back onto the hub and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

5. Brake System Check

• Reconnect the battery.
• Pump the brake pedal several times to ensure proper brake engagement before driving.
• Check for any brake fluid leaks around the calipers and lines.
