Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- Anti-squeal grease
- Screwdriver (flathead and Phillips)
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Lift the Vehicle

Loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground.
Use the jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels by completely unscrewing the lug nuts.

3. Inspect and Replace Brake Pads

Removing Brake Pads:
- Remove the caliper bolts using the socket set to detach the caliper from the rotor.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid straining the brake line.
- Remove the brake pads from the caliper bracket.
Inspecting Brake Pads and Rotors:
- Check the brake pads for wear indicators; replace if they are worn down to 3mm or less.
- Inspect the rotors for grooves, scoring, or excessive rust. Resurface or replace if necessary.
Installing New Brake Pads:
- Apply a thin layer of anti-squeal grease to the back of the new brake pads.
- Install the new brake pads into the caliper bracket.

4. Reassemble the Brake System

Reattach the caliper over the new brake pads and secure it with the caliper bolts.
Use the torque wrench to tighten the caliper bolts to the manufacturer's specified torque (usually around 25-35 lb-ft, but check your service manual for specifics).

5. Reinstall Wheels and Lower Vehicle

Place the rear wheels back onto the hubs and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Once on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically around 75-90 lb-ft).
