Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure electrical safety during the repair process.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads need inspection/replacement.
Secure the vehicle with jack stands.

3. Remove Wheel

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

4. Inspect and Remove Brake Pads

Locate the caliper and remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord or similar method to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.

5. Install New Brake Pads

Apply brake grease to the back of the new brake pads (as per manufacturer's specifications) to prevent noise.
Install the new brake pads into the caliper bracket, ensuring they are seated properly.
Reinstall the caliper over the new pads and tighten the caliper mounting bolts to the manufacturer's specified torque.

6. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even seating.
Lower the vehicle back to the ground and reconnect the battery.
Pump the brake pedal a few times to ensure proper pad seating and brake function.
