Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheels

Sub-steps:
1. Loosen lug nuts while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Components

Rotors:
1. Remove the brake caliper by unbolting it and securing it away from the rotor.
2. Slide off the rotor; check for warping or uneven wear.
3. If warped, replace with new rotors.
Brake Pads:
1. Check the thickness of the brake pads. If worn below the manufacturer's minimum specification, replace with new pads.
2. Clean the caliper bracket and apply brake grease to the contact points.

4. Inspect Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and ball joints for wear.
2. Replace any worn suspension components as necessary.

5. Reassemble and Install Wheels

Sub-steps:
1. Reinstall the rotor and caliper.
2. Tighten caliper bolts to the manufacturer’s torque specification.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
