Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and wear safety glasses.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel: Use a socket set to loosen and remove the lug nuts and take off the wheel.
2. Remove the brake caliper: Unbolt the caliper using a socket wrench, and hang it securely to avoid straining the brake line.
3. Check brake pads: Inspect for uneven wear; replace if worn.
4. Measure rotor thickness: Use a micrometer to check for warping; replace if below manufacturer specifications.
5. Install new brake pads and rotors: Follow manufacturer specifications for torque values when reassembling.

3. Examine Suspension Components

Sub-steps:
1. Visually inspect tie rods and control arms for signs of wear or play.
2. Check the ball joints for looseness by applying pressure and checking for movement.
3. Replace any components that show significant wear or damage, following manufacturer torque specifications upon reinstallation.

4. Caliper Check and Replacement (if necessary)

Sub-steps:
1. Inspect caliper operation: Check for sticking or seizing by manually moving the caliper piston.
2. Replace the caliper if it does not operate smoothly.
3. Bleed the brake system to remove any air: Use a brake bleeder kit and follow proper bleeding sequence.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure the alignment is adjusted according to manufacturer specifications.
