Solution

1. Preparation

Gather tools and materials required for the replacement.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

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

4. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the brake rotor and support it with a bungee cord to avoid strain on the brake line.

5. Remove Old Brake Pads

Slide the old brake pads out of their brackets.
Inspect the caliper for damage or wear.

6. Install New Brake Pads

Insert new brake pads into the caliper bracket, ensuring they are positioned correctly.
Apply brake grease to the back of the pads if recommended.

7. Reinstall Brake Caliper

Compress the caliper piston using a brake caliper tool to allow enough space for the new pads.
Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications.

8. Reinstall 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.

9. Test the Brakes

Pump the brake pedal several times to ensure proper brake pad seating.
Check for any leaks around the caliper and ensure the brake system functions correctly.
