why is my BMW 5 Series F10/F11 (2010-2017) making a grinding noise when braking

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety.

2. Remove Wheel

• Use a jack to lift the vehicle and secure it with jack stands.
• Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

• Remove the caliper bolts with a socket wrench and slide the caliper off the rotor.
• Carefully support the caliper to avoid stressing the brake line.
• Remove the old brake pads from the caliper bracket.
• Compare the old pads to new ones for thickness and wear.
• Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

• Remove the rotor by taking off any retaining screws or clips.
• Inspect the rotor surface for grooves or excessive wear.
• If replacement is needed, install the new rotor, ensuring it is seated correctly.

5. Reassemble Components

• Reinstall the caliper over the new brake pads.
• Tighten caliper bolts to the manufacturer's specified torque (typically around 25-30 Nm).
• Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

• Lower the vehicle and remove the jack stands.
• Tighten the lug nuts in a crisscross pattern to the specified torque (typically around 100 Nm).
• Reconnect the battery.
