Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp, and a flathead screwdriver.
Sub-steps:
1. Park the vehicle on a flat surface and set the parking brake.
2. Loosen the lug nuts on the rear wheels without removing them.
3. Use a jack to lift the rear of the vehicle and secure it with jack stands.

2. Remove Wheel

Sub-steps:
1. Remove the lug nuts completely and take off the rear wheel.
2. Place the wheel under the vehicle for added safety.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper bolts and use the socket set to remove them.
2. Carefully slide the caliper off the rotor. Do not let it hang by the brake line; use a bungee cord to secure it to the suspension.

4. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Clean the caliper bracket and the area where the pads sit with brake cleaner.
3. Install the new brake pads into the caliper bracket, ensuring they are oriented correctly.

5. Compress Caliper Piston

Sub-steps:
1. Use a C-clamp to compress the caliper piston back into the caliper housing to make room for the new pads.
2. Ensure the piston is fully retracted before reinstallation.

6. Reinstall Brake Caliper

Sub-steps:
1. Carefully slide the caliper back over the new brake pads.
2. Reinstall and tighten the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).

7. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands and then fully tighten the lug nuts in a criss-cross pattern to the manufacturer’s torque specifications (typically around 120 Nm).
