Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, impact wrench (optional)
Remove the wheel to access the brake assembly.
Inspect the brake rotors for warping or excessive wear (check for a run-out using a dial indicator if available).
If warped, unbolt the rotors and replace them with new ones, ensuring to clean the hub surface before installation.
Torque the new rotors to manufacturer specifications.

3. Inspect and Replace Brake Pads

Remove the caliper from the rotor by unbolting it.
Inspect the brake pads for thickness; replace if they are below the minimum thickness (usually 3mm or less).
If replacing pads, apply brake grease to the backing of the new pads and install them.
Reinstall the caliper and torque bolts to manufacturer specifications.

4. Wheel Alignment and Balancing

Tools Required: Alignment machine (if available)
Check the alignment settings using an alignment tool.
Adjust alignment as necessary to manufacturer specifications.
Balance the wheels if there is noticeable uneven wear or vibration.

5. Suspension Inspection

Inspect suspension components like ball joints, tie rods, and bushings for wear or damage.
Replace any worn parts as needed.
