Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Tools Required: Jack, jack stands
Use a jack to lift the vehicle and secure it on jack stands to safely access the brake components.

3. Remove Wheel

Tools Required: Lug wrench
Loosen the lug nuts and remove the wheel to gain access to the brake assembly.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are oriented correctly.
Safety Warning: Ensure the caliper does not hang by the brake line to avoid damage.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface; if damaged, remove the rotor by unscrewing the retaining screws (if equipped).
2. Install new rotors, applying a small amount of anti-seize compound to the mounting surface.
3. Torque the rotor screws to the manufacturer's specifications (typically around 10-15 ft-lbs).

6. Reassemble Brake Components

Reinstall the caliper and tighten the caliper bolts to the manufacturer's torque specifications (approximately 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a star pattern to the specified torque (usually around 100-110 ft-lbs).

7. Lower Vehicle and Test

Lower the vehicle from the jack stands and remove the jack.
Pump the brake pedal to ensure proper brake pad seating before driving.
