Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery’s negative terminal to avoid accidental electrical issues.

2. Remove the Wheel

Loosen the lug nuts on the rear wheel using a lug wrench.
Raise the vehicle using a floor jack and support it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (typically 14mm or 17mm).
Remove the caliper bolts with a socket and ratchet.
Carefully slide the caliper off the brake rotor, using a bungee cord to hang it from the suspension to avoid stress on the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the new brake pads with the old ones to ensure proper fit.
Apply brake grease to the back of the new pads and install them in the caliper bracket.

5. Inspect and Replace the Brake Rotor (if needed)

Check the rotor for scoring or warping; if damaged, replace it.
To remove the rotor, locate and remove any retaining screws and slide the rotor off the hub.
Install the new rotor, ensuring it is properly seated.

6. Reinstall the Brake Caliper

Slide the caliper back onto the new pads and rotor.
Reinstall the caliper mounting bolts and tighten them to the manufacturer’s torque specifications (usually around 25-35 ft-lbs).

7. Reattach the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the vehicle.
Once on the ground, tighten the lug nuts to the proper torque specification (usually 76-83 ft-lbs).

8. Final Checks

Reconnect the battery’s negative terminal.
Pump the brake pedal several times to ensure proper pad seating and brake pressure.
