Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Lift the Vehicle

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

3. Remove the Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Remove Old Brake Pads

Locate the caliper assembly and remove the bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it with a bungee cord or rope to prevent strain on the brake line.
Remove the old brake pads from the caliper bracket.

5. Inspect and Clean

Inspect the caliper and rotor for damage or excessive wear.
Clean the caliper bracket with brake cleaner to remove dust and debris.

6. Install New Brake Pads

Apply anti-squeal grease to the back of the new brake pads.
Position the new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 25 Nm).

7. Reassemble Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the manufacturer's specifications (generally around 120 Nm).

8. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the new pads against the rotors.
