Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and place it on jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
- Remove the old brake pads from the caliper bracket.
Replace Brake Pads:
- Install new brake pads (ensure they are the correct type for the vehicle).
- Apply brake grease to the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- If the rotors are below minimum thickness or damaged, they should be replaced.
Replace Rotors:
- Remove the caliper bracket using a socket wrench.
- Slide off the old rotor from the hub.
- Install the new rotor and secure it with the appropriate torque specifications (typically 70-85 ft-lbs).

5. Reassemble Braking System

Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications.
Reinstall the caliper over the new brake pads.
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

6. Final Checks

Lower the vehicle from the jack stands.
Pump the brake pedal multiple times to seat the brake pads.
Check brake fluid level and top off if necessary.
