Solution

1. Preparation

Gather necessary tools and parts.
Place the vehicle on a level surface and engage the parking brake.
Use jack stands to secure the vehicle after lifting with a jack.

2. Replace Brake Pads and Rotors

Tools Required: Socket set, brake pad spreader, torque wrench, brake cleaner.
Remove the wheel using a socket set.
Unbolt the brake caliper and hang it using a wire, avoiding stress on the brake line.
Remove the old brake pads and inspect rotors for warping.
If warped, replace the rotors; clean the rotor surface with brake cleaner.
Install new brake pads and reassemble the caliper.
Torque caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).

3. Wheel Alignment and Balancing

Tools Required: Wheel alignment machine.
After replacing brake components, inspect for wheel misalignment.
Adjust alignment according to manufacturer specifications.
Balance tires if necessary to eliminate vibrations.

4. Inspect Suspension Components

Tools Required: Visual inspection tools (flashlight, mirror).
Check control arms, bushings, and tie rods for wear.
Replace any worn components as necessary to ensure stability.

5. Tire Inspection and Pressure Adjustment

Tools Required: Tire pressure gauge.
Inspect tire tread for uneven wear patterns.
Adjust tire pressures to recommended levels as found on the driver’s door jamb.
