Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Tools Required: Socket set, lug wrench.
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, torque wrench.
Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it (do not hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads ensuring proper orientation.
5. Compress the caliper piston using a brake pad spreader to fit over the new pads.

4. Inspect and Replace Rotors (if necessary)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the caliper bracket by unscrewing the bolts.
2. Slide the rotor off the hub; if it's stuck, gently tap it with a rubber mallet.
3. Inspect for damage; replace with new rotors if warped or scored.
4. Install the new rotor onto the hub.

5. Reassemble Braking Components

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the caliper bracket and torque to manufacturer specifications (usually around 80-100 lb-ft).
2. Reattach the caliper over the new pads and secure with caliper bolts.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Tools Required: None.
Sub-steps:
1. Lower the vehicle and tighten the lug nuts in a crisscross pattern to the specified torque (typically 75-85 lb-ft).
2. Pump the brake pedal a few times to seat the pads against the rotors.
