Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves during maintenance.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the brake caliper bolts using a socket set.
3. Slide the caliper off the rotor and support it without putting strain on the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Compare new pads with old ones to ensure proper fit.
6. Install new brake pads in the caliper bracket.
7. Reattach the caliper over the new pads and tighten bolts to manufacturer specifications (typically around 20-25 ft-lbs).

3. Check and Replace Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" lines.
3. If low, use a brake fluid tester to check the fluid condition.
4. If the fluid is dirty or has absorbed moisture, completely drain the old fluid.
5. Refill with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
6. Bleed the brake system using a brake bleeder kit to remove air bubbles.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. After removing the wheel, visually inspect the rotor surface for grooves or scoring.
2. Use a micrometer to measure rotor thickness; if below specifications, replace the rotors.
3. Remove the caliper bracket and then the rotor.
4. Install new rotors, ensuring they are clean from any protective oils.
5. Reattach the caliper bracket and caliper, tightening to specifications.

5. Final Assembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
3. Pump the brake pedal several times to seat the brake pads against the rotors before driving.
