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 for protection.

2. Remove the Wheel

Loosen the lug nuts on the rear wheel using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor and secure it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for debris.
Install new brake pads in the caliper bracket, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor thickness with a micrometer; replace if below specifications or if scoring is present.
If replacement is needed, remove the rotor by removing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is flush against the hub and secure with retaining screws.

5. Reassemble the Brake System

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern to the manufacturer’s torque specifications (usually around 76 ft-lbs).

6. Final Checks

Pump the brake pedal several times to ensure proper seating of the brake pads.
Check the brake fluid level and top off if necessary.
Test drive the vehicle at low speeds to ensure proper brake function.
