Solution

1. Preparation

Gather tools and parts needed.
Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- C-clamp or brake caliper tool
- Socket set
Parts Required:
- New rear brake pads
- New rear brake rotors (if warped)
Ensure the vehicle is parked on a level surface and the engine is off.

2. Raise the Vehicle

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

3. Remove Brake Calipers

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or wire to avoid stressing the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket using brake cleaner.
Install new brake pads in the caliper bracket, ensuring they are oriented correctly.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for warping and thickness.
If replacement is needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is seated properly.

6. Reassemble Brake Components

Reinsert the caliper over the new pads and rotor.
Tighten the caliper mounting bolts to the manufacturer’s specified torque setting (usually around 25-35 Nm).
Reinstall the wheels and hand-tighten the lug nuts.

7. Lower the Vehicle and Finalize

Lower the vehicle back to the ground and then fully tighten the lug nuts in a star pattern to the specified torque (usually around 120 Nm).
Pump the brake pedal a few times to seat the brake pads against the rotors.
