Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the brake caliper by unbolting it and securing it away from the rotor with a bungee cord.
3. Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
4. Inspect the rotor for warping; replace if necessary.
5. If replacement is needed, install the new rotor, ensuring it is properly seated and torqued to manufacturer specifications (usually around 100 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Check the brake pad thickness and replace if worn below the manufacturer's minimum specification (typically 3 mm).
3. Apply brake grease to the backing of the new pads to prevent squeaking.
4. Install the new brake pads into the caliper bracket.

4. Check and Adjust Wheel Alignment

Sub-steps:
1. Reinstall the wheel and lower the vehicle to the ground.
2. Drive to an alignment shop or perform a DIY alignment using alignment tools.
3. Adjust camber, caster, and toe settings per specifications.

5. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, tie rods, and bushings for any signs of wear or damage.
2. Replace any worn suspension components as necessary.
