Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during brake system work.

2. Inspect and Replace Brake Components

Brake Pads:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; replace if they are below 3mm.
- Use a brake pad spreader to compress the caliper piston if necessary.
Brake Rotors:
- Check for warpage using a dial indicator; replace if runout exceeds manufacturer specifications (typically 0.002 inches).
- If rotors are within spec but have surface rust or scoring, consider resurfacing them.

3. Reassemble and Torque Components

Reinstall the brake caliper over the new pads and rotor.
Secure caliper bolts to the manufacturer's torque specifications (typically 20-25 ft-lbs).
Reinstall the wheel and torque lug nuts to specified values (typically 80-100 ft-lbs).

4. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper seating of new components.
Check brake fluid level and top up if necessary.
