Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake pad spreader, brake cleaner, safety goggles, gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use the jack to lift the vehicle and place it securely on jack stands.
Remove the wheel using the lug wrench to expose the brake assembly.

3. Remove Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor and support it using a bungee cord or wire to avoid stressing the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake pad spreader to compress the caliper piston back into its housing, making room for the new pads.
Install the new brake pads into the caliper bracket.

5. Reattach Brake Caliper

Position the caliper over the new brake pads and align it with the rotor.
Reinstall the caliper mounting bolts and tighten to the manufacturer's specified torque (usually around 25-30 Nm).
Ensure the caliper slides freely.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove them.
Tighten the lug nuts to the manufacturer’s specified torque (usually around 120 Nm).

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper brake pad seating and restore brake pressure.
