Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Pads

Remove the wheel to access the brake assembly.
Inspect the brake pads for wear; replace if they are below the minimum thickness (generally 3mm).
Use a torque wrench to install new pads to manufacturer specifications (usually around 25-30 Nm).

3. Inspect and Resurface or Replace Brake Rotors

Check the rotors for warping using a dial indicator gauge.
If warped beyond acceptable limits (typically more than 0.005 inches), replace the rotors.
If within tolerance, resurface the rotors to ensure a flat surface.
Clean the rotor surfaces with brake cleaner before reinstallation.

4. Inspect Tires and Suspension

Examine the tires for uneven wear patterns; replace if necessary.
Check tire pressure and adjust to manufacturer specifications.
Inspect suspension components (e.g., control arms, bushings) for any signs of wear or damage; replace as needed.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the specified value (usually around 100-120 Nm).
Reconnect the battery.
Test drive the vehicle to assess brake performance and vibrations.
