Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Rear Wheels

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Use a jack to lift the rear of the vehicle and secure with jack stands.
3. Remove the lug nuts completely and take off the rear wheels.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, ratchet set, brake cleaner.
Sub-steps:
1. Remove the caliper bolts and gently slide the caliper off the rotor.
2. Support the caliper with a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and inspect for any damage.
5. Install new brake pads in the caliper bracket.
6. Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications (typically around 25 Nm).

4. Check and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if rotors are stuck), torque wrench.
Sub-steps:
1. If rotors are worn or damaged, remove the caliper bracket and bolts.
2. Slide the rotor off the hub. If stuck, use a rotor puller.
3. Install new rotors, ensuring they are clean and free of oil.
4. Torque the rotor retaining screws to manufacturer specifications (typically around 10 Nm).

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the caliper assembly and ensure all bolts are secured.
2. Reattach the wheels and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to manufacturer specifications (typically around 120 Nm).
4. Pump the brake pedal to seat the pads against the rotors before driving.
