Solution

1. Preparation

Gather tools and parts needed for the repair. Ensure the vehicle is parked on a flat surface and engage the parking brake.
Tools Required:
- Jack and jack stands
- Socket set
- Brake cleaner
- Torque wrench
- C-clamp or brake caliper tool

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor and support it using a bungee cord or similar method to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the new brake pads for compatibility and any visible damage.
Install new brake pads, ensuring they are seated correctly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any visible scoring or warping.
If replacement is needed, unbolt the rotor from the hub.
Clean the hub surface with brake cleaner to ensure a proper fit for the new rotor.
Install the new rotor, securing it with the appropriate torque specifications.

5. Reassemble Brake Components

Reposition the brake caliper over the new pads and rotor.
Reattach and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands and remove the jack.
Tighten the lug nuts fully after lowering.
Pump the brake pedal several times to ensure proper brake pad seating and to restore brake feel.
