Solution

1. Preparation

Gather tools and parts: Ensure you have the necessary tools and replacement parts.
Safety gear: Wear safety glasses and gloves.

2. Raise the Vehicle

Tools Required: Jack and jack stands
Instructions:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Use a jack to lift the vehicle and secure it with jack stands.

3. Remove Wheel

Tools Required: Lug wrench
Instructions:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Remove the lug nuts and take off the wheel to access the brake assembly.

4. Remove Brake Caliper

Tools Required: Socket set
Instructions:
1. Locate the caliper bolts and remove them using the socket wrench.
2. Carefully slide the caliper off the brake rotor, supporting it with a bungee cord to avoid stress on the brake line.

5. Replace Brake Pads

Tools Required: C-clamp or brake caliper tool
Instructions:
1. Remove the old brake pads from the caliper bracket.
2. Use the C-clamp to compress the caliper piston back into the caliper housing.
3. Install the new brake pads, ensuring they fit snugly in the caliper bracket.

6. Reassemble Components

Instructions:
1. Slide the caliper back over the new brake pads and secure it with the caliper bolts.
2. Tighten the bolts to the manufacturer’s specified torque (usually around 25-35 lb-ft).

7. Reinstall Wheel

Instructions:
1. Place the wheel back on the hub and hand tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.

8. Final Check

Instructions:
1. Pump the brake pedal several times to ensure proper seating of the brake pads.
2. Inspect for any leaks around the caliper area.
