Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gear (gloves and goggles).

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, rotor puller, torque wrench, brake cleaner.
Loosen the lug nuts and raise the vehicle using a jack. Secure it on jack stands.
Remove the wheel by taking off the lug nuts.
Inspect the brake rotor for warping using a dial indicator; if warped beyond specifications, proceed to replace.
Remove caliper bolts using a socket; slide the caliper off the rotor and secure it without stretching the brake line.
Remove the old rotor; if it’s stuck, use a rotor puller.
Install the new rotor and ensure it is seated properly. Clean it with brake cleaner to remove any protective coating.
Reinstall the caliper and tighten bolts to the manufacturer's torque specifications.

3. Inspect and Replace Brake Pads

Inspect brake pads for thickness; replace if they are worn to the minimum specification.
Tools Required: Same as above.
Remove the caliper bracket if necessary to access the pads.
Slide out old brake pads and replace them with new ones.
Apply brake grease on the back of the pads to prevent squeaking.
Reassemble the caliper and ensure it seats correctly.

4. Check Suspension Components

Tools Required: Wrench set, pry bar.
Inspect control arms, tie rods, and bushings visually for any signs of wear or damage.
Use a pry bar to check for play in the components.
Replace any worn or damaged parts as necessary.

5. Tire and Wheel Check

Inspect tires for uneven wear and ensure they are properly inflated.
Tools Required: Tire pressure gauge, tire balancer (if available).
Balance tires if necessary; consider rotation if uneven wear is detected.
