Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel by loosening the lug nuts.
- Inspect the brake rotors for warping or uneven wear.
- If the rotors are damaged, remove the caliper by unbolting it and slide it off the rotor.
- Remove the rotor; if it is stuck, tap it gently with a rubber mallet.
- Install new rotors, ensuring they are properly seated.
- Reinstall the caliper and bolt it securely to the mounting bracket, tightening to manufacturer specifications.

3. Inspect Brake Pads

Sub-steps:
- Check the thickness of the brake pads. If they are below the minimum thickness, replace them.
- If replacing, remove the brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads before installation.
- Reinstall the new pads into the caliper bracket.

4. Wheel Alignment Check

Sub-steps:
- After completing brake repairs, inspect the alignment.
- If necessary, take the vehicle to a professional alignment shop to ensure proper wheel alignment and suspension geometry.
