Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and allow the brakes to cool.

2. Inspect Brake Components

Remove the wheel: Use a socket set to loosen and remove the lug nuts; carefully take off the wheel.
Examine brake pads: Check for uneven wear or thickness below the manufacturer's specification; replace if necessary.
Inspect rotors: Look for warping, scoring, or excessive rust; machine or replace if defects are found.

3. Check Suspension and Wheel Alignment

Inspect suspension components: Look for worn or damaged parts, such as control arms, tie rods, and bushings.
Perform wheel alignment: If misalignment is detected, adjust according to manufacturer specifications.

4. Brake Fluid and System Check

Check brake fluid: Ensure the fluid is at the recommended level and is clear; if contaminated, flush the system.
Bleed the brakes: If air is present in the system, bleed each brake line using a brake bleeder kit.

5. Reassemble and Test

Reattach the wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle: Use a jack to lift the vehicle back to its original position.
Torque lug nuts: Use a torque wrench to tighten lug nuts to the manufacturer's specified torque value.
