Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electronic braking systems).

2. Remove Wheels

Use a lug wrench to remove the lug nuts and take off the front wheels.
Safety Warning: Always use jack stands after lifting the vehicle with a jack.

3. Inspect Brake Rotors

Remove the brake caliper by unbolting it from the bracket.
Hang the caliper securely without stressing the brake line.
Remove the brake rotor and inspect for warping or uneven surfaces.
- If warped, replace the rotors.
- If within tolerance, proceed to clean and resurface if necessary.

4. Replace Brake Pads (if necessary)

Remove worn brake pads from the caliper bracket.
Install new brake pads ensuring they are properly oriented.
Lubricate caliper slide pins with high-temperature brake grease.

5. Reassemble and Torque

Reinstall the brake rotor and caliper.
Torque the caliper bolts to the manufacturer's specifications (usually around 20-25 ft-lbs).
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 100-150 ft-lbs).
