Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and safety goggles.
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Loosen the lug nuts slightly on the front wheels.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the front wheels.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts with a socket wrench (torque specifications: 79 lb-ft for caliper mounting bolts).
2. Slide the caliper off the rotor and suspend it using a wire to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket and inspect for uneven wear.
4. Check the caliper guide pins for lubrication and movement; replace if necessary.
5. Clean the brake rotor with brake cleaner; inspect for warping or scoring. Resurface or replace if needed.
6. Install new brake pads of the same type and specifications as the original.
7. Reinstall the caliper and ensure it moves freely on the guide pins.

3. Reassemble and Adjust

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 76 lb-ft).
3. Pump the brake pedal several times to ensure proper pad seating and to build brake pressure.
4. Inspect the brake fluid level and top off if necessary.
