Problem Statement

The BMW 5 Series F10/F11 (2010-2017) is experiencing shaking or vibration during braking, indicating a potential issue with the braking system or suspension components.

Estimated Time

3-5 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working underneath a vehicle.
•Allow brakes to cool before handling to prevent burns.

Symptoms

•Steering wheel vibrates when braking
•Vehicle shakes or shudders during braking
•Increased stopping distance
•Brake pedal pulsation felt
•Uneven tire wear

Diagnostic Steps

1
Inspect brake rotors for warping by measuring thickness with a micrometer.
2
Check brake pads for wear and ensure they are evenly worn.
3
Examine suspension components (control arms, bushings, tie rods) for wear or damage.
4
Inspect wheel alignment and tire balance.
5
Scan for any error codes using an OBD-II scanner that may indicate issues with the braking system.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Solution

1. Preparation

Gather tools: Socket set, torque wrench, micrometer, jack and jack stands, OBD-II scanner.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Rotors

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Use a micrometer to measure the rotor thickness. If below the minimum specification, replace.
If warped, remove the brake caliper by loosening the caliper bolts and hanging it using a wire.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, ensuring it is seated properly, and secure it with retaining screws.
Reinstall the caliper, ensuring it is torqued to manufacturer specifications.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads. If worn, remove them from the caliper bracket.
Clean the caliper bracket and apply anti-squeal lubricant to the back of the new pads.
Install the new brake pads into the caliper bracket, ensuring they fit snugly.
Reinstall the caliper over the new pads and torque the caliper bolts to specifications.

4. Inspect Suspension Components

Visually inspect control arms, bushings, and tie rods for any signs of wear or damage.
If any component is found defective, replace it using appropriate tools and procedures.

5. Wheel Alignment and Balancing

After all brake and suspension work, take the vehicle to a professional alignment shop.
Request a wheel balancing check to ensure even tire wear and proper handling.
