Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Secure with jack stands for safety.

3. Remove Rear Wheels

Use a socket set to remove the lug nuts.
Take off the rear wheels to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect: Check the rear brake rotors for warping using a dial indicator tool.
Replace (if necessary):
- Remove the caliper by unscrewing the mounting bolts.
- Slide the caliper off the rotor and suspend it with a bungee cord.
- Remove the rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor, ensuring it's correctly aligned and secured.

5. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear.
Replace (if necessary):
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads.
- Install the new pads into the bracket.

6. Reassemble Components

Reattach the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 lb-ft).
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 lb-ft).

7. Brake Fluid Check

Check the brake fluid level and top off if necessary with DOT 3 or DOT 4 brake fluid.
Bleed the brakes if air was found in the lines.
