Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the wheel using a lug wrench.
- Take off the brake caliper by removing the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord or rope.
- Remove the brake pads from the caliper bracket.
- Check the rotor for warping using a dial indicator or visual inspection.
- If warped, replace with new rotors, ensuring proper torque (typically 70-100 lb-ft) when installing the new rotors.

3. Replace Brake Pads

Sub-steps:
- Inspect the old brake pads for thickness; if worn below specifications, replace them.
- Apply brake grease to the back of the new pads to prevent noise.
- Install the new pads into the caliper bracket.
- Reattach the caliper over the new pads and torque the caliper bolts to specification.

4. Inspect Wheel Bearings and Suspension

Sub-steps:
- Remove the wheel again if necessary to access the hub assembly.
- Check for any play in the wheel bearing by shaking the wheel from top to bottom.
- If there is play, replace the wheel bearing assembly.
- Inspect control arms and bushings for any signs of wear or damage and replace if necessary.

5. Alignment Check

Sub-steps:
- After reassembly, perform a wheel alignment check.
- Adjust the alignment according to specification if necessary.
