Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery if working on electronic brake 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 securely to avoid strain on the brake line.
3. Remove the brake rotor from the hub.
4. Measure the thickness of the rotor; if below specifications or warped, proceed to replace.
5. Install new rotors, ensuring they are properly seated and torqued to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Clean the caliper bracket and apply brake grease to the pad contact points.
3. Install new brake pads, ensuring they are oriented correctly.
4. Replace the caliper over the new pads and tighten to the specified torque.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Visually inspect tie rods, control arms, and bushings for wear.
2. Replace any worn components using a socket set and torque to specifications.
3. Re-check alignment post-replacement.
