Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Unbolt the brake caliper and hang it using a bungee cord to avoid putting stress on the brake line.
3. Remove the brake rotor. If it is stuck, gently tap it with a rubber mallet.
4. Measure rotor thickness and check for warping using a dial indicator. Replace if necessary.
5. Clean the hub surface with a wire brush to remove any rust or debris before installing the new rotor.
6. Install the new rotor, ensuring it sits flush against the hub.

3. Replace Brake Pads

Sub-steps:
1. Remove old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake caliper tool and ensure it is fully retracted.
3. Install new brake pads, ensuring they are properly seated in the caliper bracket.
4. Reattach the brake caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Visually inspect control arms, bushings, and ball joints for wear or damage.
2. If any components are found to be defective, replace them accordingly.
3. Make sure to torque all fasteners to the manufacturer's specifications.

5. Final Assembly

Reinstall the wheel and torque the lug nuts to the proper specification.
Reconnect the battery.
