Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle and secure it with jack stands.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
- Remove the wheel on the left side.
- Inspect brake pads for uneven wear; replace if necessary.
- Check the rotor for warping or scoring; replace if damaged.
- Reinstall new or resurfaced rotors and new brake pads, ensuring proper orientation.
Brake Caliper:
- Remove the caliper from the bracket.
- Inspect the caliper for seized pistons; clean or replace if needed.
- Reinstall caliper using a torque wrench set to manufacturer specifications (typically 25-35 ft-lbs).

3. Brake Lines Inspection and Replacement

Inspect the brake line for any visible leaks or damage.
If damaged, replace the brake line with a new one, ensuring proper fittings and routing.
Bleed the brake system to remove any air using a brake bleeder kit.

4. Suspension Component Check

Inspect control arms, bushings, and tie rods for wear.
Replace any worn or damaged components with OEM parts.
Reassemble and torque all suspension components to manufacturer specifications.

5. Wheel Alignment

After completing the brake and suspension work, perform a wheel alignment to ensure proper handling and tire wear.
