Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Engage the parking brake for safety.
Wear safety glasses and gloves.

2. Lift and Secure the Vehicle

Tools Required: Jack and jack stands
- 1. Use a jack to lift the front or rear of the vehicle.
- 1. Secure with jack stands under the vehicle's frame.

3. Remove the Wheel

Tools Required: Lug wrench
- 1. Loosen the lug nuts while the wheel is still on the ground.
- 1. Remove the lug nuts and take off the wheel.

4. Remove the Brake Caliper

Tools Required: Socket set
- 1. Locate the caliper mounting bolts and remove them using a socket.
- 1. Carefully slide the caliper off the rotor and support it with a bungee cord or similar device to avoid straining the brake line.

5. Replace the Brake Pads

Tools Required: Flat-head screwdriver (for prying if necessary)
- 1. Remove the old brake pads from the caliper bracket.
- 1. Compare the new pads with the old ones to ensure correct size.
- 1. Insert the new brake pads into the caliper bracket, ensuring they are seated properly.

6. Compress the Caliper Piston

Tools Required: C-clamp or brake caliper tool
- 1. Place the old brake pad against the piston.
- 1. Use a C-clamp to compress the caliper piston back into the caliper housing.

7. Reinstall the Brake Caliper

Tools Required: Socket set
- 1. Slide the caliper back over the new brake pads.
- 1. Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 30-35 lb-ft).

8. Reinstall the Wheel

Tools Required: Lug wrench
- 1. Place the wheel back onto the hub.
- 1. Hand-tighten the lug nuts, then lower the vehicle back to the ground.
- 1. Torque the lug nuts to the manufacturer’s specified value (usually around 100-150 lb-ft).

9. Final Steps

Tools Required: Brake cleaner
- 1. Clean the rotor surface with brake cleaner to remove any grease or debris.
- 1. Pump the brake pedal several times to seat the brake pads against the rotors.
