Solution

1. Prepare the Vehicle

Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Loosen the wheel lug nuts slightly without removing them.
- Jack up the vehicle and secure it on jack stands.
Tools Required: Jack, jack stands, lug wrench

2. Remove the Wheel

Sub-steps:
- Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench

3. Inspect and Replace Brake Components

Sub-steps:
- Inspect the brake rotors for warping or scoring; replace if necessary.
  - Rotor Replacement: Remove caliper bolts, hang the caliper using a wire, and remove the rotor. Install the new rotor and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
- Check brake pads for wear; replace if thickness is below specification (usually 3mm).
  - Pad Replacement: Remove the caliper, replace the pads, and reassemble. Ensure to compress the caliper piston if necessary.
- Inspect and replace any damaged suspension components if necessary (control arms, bushings).
Tools Required: Socket set, torque wrench, brake caliper tool

4. Reassemble the Wheel

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
Tools Required: Torque wrench, lug wrench

5. Test the Brakes

Sub-steps:
- Start the vehicle and test the brakes gently at low speed to check for vibrations.
- Ensure there are no unusual noises or sensations.
