Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, caliper tool.
Remove the wheel using a socket set.
Unbolt the brake caliper and hang it securely using a wire or bungee cord (do not let it dangle on the brake line).
Remove the brake pads from the caliper bracket.
Inspect the rotors for warping using a dial indicator; if warped beyond specifications, replace them.
Clean the rotor surface with brake cleaner before installation.
Install new rotors if necessary, ensuring they are torqued to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

If brake pads are worn unevenly or below minimum thickness, replace them.
Tools Required: Caliper tool, socket set, torque wrench.
Install new brake pads into the caliper bracket, ensuring they are seated properly.
Reinstall the caliper over the new pads and torque to manufacturer specifications.

4. Inspect Suspension Components

Tools Required: Jack, jack stands, visual inspection tools.
Lift the vehicle and secure it on jack stands.
Visually inspect tie rods, control arms, and bushings for wear or damage.
Replace any worn components to maintain proper alignment and handling.

5. Tire Balance and Alignment

Tools Required: Tire balancer, alignment rack.
Check the tire balance using a tire balancer.
If tires are found to be unbalanced, balance them accordingly.
Perform a wheel alignment to ensure proper tracking.
