Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Using a jack, lift the rear of the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the rear wheel.

3. Inspect Brake Components

Remove the brake caliper bolts with a socket wrench.
Carefully slide the caliper off the brake rotor. Support it using a bungee cord or similar device to avoid stressing the brake line.
Inspect the brake pads for wear; replace if the pads are worn down to the backing plate.
Check the brake rotor for any scoring or warping; replace if necessary.

4. Replace Brake Pads/Rotors (if needed)

If replacing pads:
- Remove old pads from the caliper bracket.
- Install new pads into the bracket ensuring proper orientation.
If replacing rotors:
- Remove the old rotor from the hub.
- Install the new rotor, ensuring it is properly seated.

5. Reassemble Brake Components

Reattach the caliper over the new pads or rotor.
Tighten caliper bolts to the manufacturer’s specified torque (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle back to the ground and remove jack stands.
Tighten lug nuts to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal a few times to seat the brake pads properly.
