Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using a jack and secure it with jack stands.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Brake Rotors

Tools Required: Brake rotor removal tool, torque wrench, socket set.
Remove the wheel to access the brake components.
Loosen and remove the caliper bolts, and slide the caliper off the rotor. Support it with a bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.
Remove the rotor by unscrewing the retaining screws (if equipped) and pulling it off the hub.
Inspect the new rotor for any protective coating that may need to be cleaned.
Install the new rotor onto the hub, securing it as necessary.

3. Replace Brake Pads

Install new brake pads into the caliper bracket, ensuring proper orientation.
Compress the caliper piston using a brake caliper tool to make space for the new pads.
Reattach the caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer's specifications (usually around 25-30 Nm).

4. Reassemble and Test

Reinstall the wheel and torque the lug nuts in a star pattern to the manufacturer’s specifications (typically 100-120 Nm).
Reconnect the battery and lower the vehicle.
Perform a test drive to ensure the braking system is functioning properly and that the shaking issue is resolved.
