Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent accidental activation of electrical components.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the brake disc and suspend it using a wire hanger to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and inspect for any debris or damage.
5. Install new brake pads, ensuring they are seated correctly.
6. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specifications.

4. Inspect and Replace Brake Discs (if needed)

Tools Required: Same as above.
Sub-steps:
1. If the brake discs are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
2. Clean the hub surface to ensure proper seating of the new disc.
3. Install the new brake disc and secure it with the retaining screws.
4. Ensure the disc is properly aligned and spins freely.

5. Reassemble and Test

Tools Required: Same as above.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
3. Reconnect the battery.
4. Pump the brake pedal several times to ensure proper brake pad seating.
