Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Lift Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspection:
- Measure rotor thickness with a micrometer; compare to manufacturer specifications.
- Check for signs of warping or scoring.
Replacement:
- If warped, remove the caliper by unscrewing the caliper bolts using a socket wrench.
- Slide off the caliper and hang it using a zip tie to avoid straining the brake line.
- Remove the rotor by unscrewing the retaining screws, if applicable.
- Install new rotors, ensuring they are properly seated and securing with screws.

5. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper slides and lubricate if necessary.
Install new brake pads, ensuring proper orientation and alignment.

6. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

7. Test Brake Function

Pump the brake pedal to ensure the pads seat properly before driving.
Check for any unusual noises or vibrations upon test driving.
