my BMW 5 Series F10/F11 (2010-2017) shakes when I brake what’s wrong

Solution

1. Preparation

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

2. Remove Wheel

• Using a socket set, loosen the lug nuts while the vehicle is on the ground.
• Jack up the vehicle and secure it with jack stands.
• Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Brake Rotor Inspection

• Visually inspect the rotor surface for grooves or warping.
• If warped, remove the rotor by unscrewing the caliper mounting bolts and lifting the caliper off the rotor.
• Replace with a new rotor if necessary, ensuring proper fit and alignment.

B. Brake Pad Inspection

• Check the thickness of the brake pads. Replace if they are worn below the recommended thickness (usually 3mm).
• Remove the old pads, noting the orientation for installation of new pads.
• Install new brake pads, ensuring they are seated correctly in the caliper bracket.

4. Reassemble and Adjust

• Reinstall the caliper over the new rotor and pads.
• Torque the caliper bolts to the manufacturer’s specifications.
• Reattach the wheel and torque the lug nuts in a star pattern to the specified torque.

5. Final Checks

• Recheck brake fluid level and top up if necessary.
• Bleed the brakes if air is present in the brake lines.

Tools Required:

• Socket set
• Torque wrench
• Brake cleaner
• Jack and jack stands
• Lug wrench

Parts Required:

• Brake rotors (if warped)
• Brake pads (if worn)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Always disconnect the battery before working on electrical systems.
• Allow the vehicle to cool before working on brakes to avoid burns.
