Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and securely engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which set of brake pads needs replacing.
Secure the vehicle on jack stands to ensure safety during the process.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel to access the brake caliper and pads.

4. Remove the Brake Caliper

Locate the caliper mounting bolts and use a socket set to remove them.
Carefully slide the caliper off the brake rotor and support it using a bungee cord or similar tool to avoid straining the brake line.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compress the caliper piston back into its housing using a brake caliper tool or C-clamp to make space for the new pads.
Install the new brake pads in the caliper bracket, ensuring they are correctly aligned.

6. Reassemble

Reattach the brake caliper over the new pads and secure it with the mounting bolts. Use the manufacturer’s specified torque for these bolts.
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specifications.

7. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.

8. Test Brake Function

Before driving, pump the brake pedal several times to ensure proper seating of the brake pads and to restore brake pressure.
