Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Remove Rear Wheel

Tools Required: Lug wrench
Loosen lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the rear wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader
Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Use a brake pad spreader to push the caliper piston back into the caliper housing.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if needed)
Check the rotor for wear; if it shows significant scoring or is below minimum thickness, replace it.
If replacing, remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install the new rotor, ensuring it is seated properly.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and secure it with bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).
Pump the brake pedal a few times to ensure the brakes are re-engaged before driving.
