Solution

1. Preparation

Gather tools and parts.
Make sure the vehicle is on a level surface and parked securely.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

3. Remove Brake Components

Remove the caliper by unscrewing the caliper bolts with a torque wrench (typically around 25 Nm).
- Tools Required: Socket set, torque wrench
Carefully slide the caliper off the brake rotor. Suspend it using a wire hanger to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace Components

Check the brake pads for wear; replace if they are worn down to the indicator.
- Parts Required: New brake pads (OEM recommended)
Inspect the brake rotor; replace if grooves or scoring are present.
- Parts Required: New brake rotors (if necessary)
Clean the caliper and bracket with brake cleaner to remove dust and debris.
Apply anti-squeal lubricant to the back of the new brake pads.

5. Reassemble Brake Components

Place the new brake pads into the caliper bracket.
Reinstall the caliper over the brake pads and rotor, ensuring proper alignment.
Tighten the caliper bolts to the specified torque value (around 25 Nm).

6. Reinstall Wheels and Lower Vehicle

Put the rear wheels back on and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specifications.

7. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and pump the brake pedal a few times to ensure proper brake pad seating.
