Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery cable to prevent any electrical issues.

2. Remove Rear Wheel

Use a jack and jack stands to lift the rear of the vehicle safely.
Remove the lug nuts and take off the rear wheel to access the brakes.

3. Inspect and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides for corrosion and clean or lubricate as necessary.
Install new brake pads, ensuring they are correctly positioned in the caliper bracket.
Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 20-25 ft-lbs).

4. Inspect and Replace Rotors (if necessary)

If rotors are worn beyond specification (thickness or damage), remove them by unscrewing the rotor retaining screws (if equipped).
Install new rotors, ensuring they are clean and free of residue.
Reattach the brake caliper with the new pads.

5. Bleed Brake System

Refill the brake fluid reservoir with the appropriate fluid type (DOT 3 or DOT 4 as specified).
Bleed the brake lines using a brake bleeder kit to remove any air and ensure proper brake pedal feel.
Monitor the fluid level and top up as needed.

6. Reassemble and Test

Reinstall the rear wheel and lug nuts, torquing them to the manufacturer's specifications (typically around 80-100 ft-lbs).
Reconnect the negative battery cable.
Lower the vehicle and perform a test drive to ensure proper brake function.
