Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools and parts.
Safety warning: Allow the vehicle's brakes to cool before working on them.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Components

Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor.
- Inspect the brake pads for thickness; if they are below 3mm, replace them.
- Remove old pads and install new pads, ensuring they are properly seated.
Brake Rotors:
- If rotors are scored or warped, remove them by unscrewing the rotor retaining screws (if applicable).
- Clean the hub surface with a wire brush.
- Install new rotors, torque screws to manufacturer's specifications (typically 10-15 ft-lbs).
Caliper Inspection:
- Check caliper slides for corrosion or binding; lubricate if necessary with brake grease.
- Ensure caliper pistons move freely; replace caliper if it is stuck or damaged.

4. Reassemble Brake Assembly

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's torque specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to specification (typically 80-100 ft-lbs).

5. Final Checks

Pump the brake pedal several times to ensure proper pad seating.
Check brake fluid level and top off if necessary.
