Solution

1. Preparation

Gather tools and parts needed for the replacement.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads need to be replaced.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Remove the Brake Caliper

Use a wrench to unbolt the caliper from the mounting bracket.
Carefully slide the caliper off the brake rotor and secure it using a bungee cord or similar tool to avoid straining the brake line.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new brake pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

6. Reassemble the Brake Assembly

Reattach the brake caliper over the new pads and ensure it is secured with the original bolts.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs, but refer to the service manual for exact values).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
