Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks in front of the front tires for safety.

2. Remove the Rear Wheels

Loosen the lug nuts with a lug wrench.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheels.

3. Inspect and Replace Brake Pads

Inspect the Brake Pads:
- Remove the caliper by loosening the caliper bolts with a socket set.
- Slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
- Check the pad thickness; replace if less than 3mm.
Replace the Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads into the caliper bracket.
- Apply brake grease to the backing of the pads to prevent squeaking.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect the Rotors:
- Check for deep grooves or warping.
Replace Rotors (if damaged):
- Remove the caliper bracket by loosening the bolts.
- Slide the rotor off the hub; if stuck, use a rubber mallet to gently tap it.
- Install the new rotor, ensuring it sits flush against the hub.
- Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal a few times to seat the new pads.
