Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly with the wheel on the ground.
2. Jack up the vehicle using a floor jack.
3. Securely place jack stands under the vehicle.
4. Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Tools Required: Torque wrench, caliper tool (if necessary).
Sub-steps:
1. Visually inspect the brake pads for uneven wear; replace if necessary.
2. Measure the thickness of the rotors with a micrometer.
3. Check for warping by placing a straight edge across the rotor and measuring any gaps.
4. Inspect the caliper for proper operation and ensure it is not sticking.

4. Replace Brake Pads and/or Rotors (if needed)

Tools Required: Torque wrench, brake cleaner, new brake pads, new rotors (if applicable).
Sub-steps:
1. Remove the caliper bolts and gently slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. If replacing rotors, remove the rotor from the hub.
4. Install the new rotor and torque the retaining screws to the manufacturer's specifications.
5. Install the new brake pads into the caliper bracket and reattach the caliper.
6. Torque the caliper bolts to the manufacturer's specifications.

5. Reassemble and Test

Tools Required: Same as above.
Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer's specifications using a star pattern.
4. Test the brakes by pressing the pedal several times to seat the pads.
