why does my BMW 5 Series steering wheel vibrate when I brake

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety goggles and gloves.

2. Inspect and Replace Brake Components

1. Remove Wheels

   • Loosen lug nuts slightly while the vehicle is on the ground.
   • Lift the vehicle with a jack and secure it with jack stands.
   • Remove the lug nuts completely and take off the wheels.

2. Inspect Brake Pads and Rotors

   • Check the thickness of the brake pads; replace if below manufacturer's specifications (usually less than 3mm).
   • Inspect the rotors for warping or scoring; if warped, replace rotors.
   • Clean the rotor surface with brake cleaner if reusing.

3. Replace Brake Pads and Rotors

   • If necessary, remove the caliper bolts and slide the caliper off the rotor.
   • Replace the brake pads by sliding them out and installing new ones.
   • Install new rotors if required, ensuring the correct orientation.
   • Reinstall the caliper and torque bolts to manufacturer specifications.

3. Suspension Inspection and Repair

1. Check Control Arms and Bushings

   • Visually inspect control arms and bushings for signs of wear or damage.
   • Replace any worn or damaged components to restore proper alignment.

2. Alignment and Balancing

   • After repairs, perform a wheel alignment to ensure proper tracking.
   • Have the wheels balanced to eliminate vibration during driving.
