Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench, anti-seize lubricant.
Ensure the vehicle is on a flat surface and turn off the ignition.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Rear Wheel

Loosen the lug nuts slightly while the car is on the ground.
Jack up the rear of the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheel to access the brake components.

3. Remove Brake Caliper

Use a socket to remove the caliper bolts and slide the caliper off the brake rotor.
Support the caliper using a bungee cord or rope to avoid putting stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket. If they are worn down, replace them with new pads.
Clean the caliper bracket and apply anti-seize lubricant to the backing plates of the new pads to reduce noise.
Install the new brake pads into the bracket.

5. Inspect and Clean Brake Rotor

Check the rotor for any signs of scoring or wear. If the rotor is damaged, it should be replaced.
If the rotor is in good condition, clean it with brake cleaner to remove any dust or debris.
If necessary, machine the rotor to ensure a smooth surface.

6. Reassemble Components

Slide the caliper back onto the brake pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
