Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, brake cleaner, wire brush, and safety glasses.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Loosen the rear wheel lug nuts slightly before lifting the vehicle.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels to access the brakes.

3. Remove Brake Components

Brake Pads:
- Remove the caliper mounting bolts using a socket.
- Carefully slide the caliper off the brake rotor.
- Remove the old brake pads from the caliper brackets.
Brake Rotor:
- If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace Components

Brake Pads:
- Compare the thickness of the old pads to new ones; replace if worn down (less than 3mm).
Brake Rotor:
- Inspect for deep grooves or warping. Replace if damaged.
Calipers and Hardware:
- Ensure calipers are functioning correctly. Replace if leaking or damaged.
- Clean and inspect brake hardware; replace if worn.

5. Reassemble Brakes

Install new brake pads into the caliper brackets.
Slide the rotor back onto the hub.
Reattach the caliper over the new pads and torque the mounting bolts to manufacturer specifications (generally around 25-35 ft-lbs).

6. Reinstall Wheels

Place the wheels back onto the hubs and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically around 100-120 ft-lbs).

7. Final Checks

Pump the brake pedal a few times to ensure proper pad seating.
Check brake fluid levels and top up if necessary.
