Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, brake grease, torque wrench.
Raise the rear of the vehicle using a jack and secure it on jack stands.
Remove the rear wheels using a lug wrench.

2. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or rope to avoid straining the brake line.
Safety Warning: Do not allow the caliper to hang by the brake line.

3. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for rust or debris.
Apply brake grease to the back of the new brake pads to prevent noise.
Install the new brake pads into the caliper bracket.

4. Inspect and Replace Rotor (if needed)

If rotors are worn, remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Clean the hub surface and install the new rotor.
Secure the rotor with retaining screws if applicable.

5. Reinstall Brake Caliper

Slide the caliper over the new brake pads and rotor.
Reinstall the caliper mounting bolts and tighten to the manufacturer's specifications (typically around 20-30 ft-lbs).

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).
Pump the brake pedal several times to seat the brake pads against the rotor before driving.
