Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Rear Wheel

Tools Required: Jack and jack stands, lug wrench.
Loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
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 to avoid straining the brake line.
Inspect the caliper for any signs of leakage or damage.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the condition of the brake hardware (clips and shims); replace if necessary.
Install new brake pads, ensuring they are properly aligned.
Apply anti-squeal lubricant to the back of the pads if recommended by the manufacturer.

5. Inspect and Replace Brake Rotor (if necessary)

Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Inspect the new rotor for any protective coating and clean it with brake cleaner.
Install the new rotor onto the hub, securing it with retaining screws.

6. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Torque the caliper mounting bolts to the manufacturer's specified value.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications in a crisscross pattern.
Reconnect the negative battery terminal.
