Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and securely elevated using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a socket set to loosen the lug nuts on the affected wheel.
Lift the vehicle using a floor jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake rotors for warping: they should be smooth and flat.
Measure rotor thickness using a micrometer; replace if below minimum specification.
Check brake pads for wear; replace if they are below 3mm thickness.

4. Replace Brake Rotors (if necessary)

Remove the caliper by unbolting it from the bracket; support it without straining the brake line.
Remove the old rotor by unbolting it from the hub.
Install the new rotor, ensuring it is aligned properly and secured with bolts to manufacturer torque specifications.

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Install new pads, ensuring proper orientation and alignment.
Reinstall the caliper over the new pads and bolt it securely.

6. Reassemble and Test

Reattach the wheel and tighten the lug nuts to manufacturer torque specifications.
Lower the vehicle and reconnect the battery.
Perform a test drive to ensure the shaking has been resolved.
