Solution

1. Preparation

Gather tools and parts needed for the brake pad replacement.
Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Brake cleaner
- C-clamp or brake caliper tool
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported on jack stands.
- Wear safety goggles and gloves.

2. Remove Wheel

Using the lug wrench, loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using the jack and support it on jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Remove Caliper and Old Brake Pads

Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the rotor. Support it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket. Note the orientation for installation of new pads.

4. Inspect and Clean Components

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

5. Install New Brake Pads

Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
Install the new brake pads in the same orientation as the old ones.
Reposition the caliper over the new pads and secure it by tightening the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-30 ft-lbs).

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).

7. Final Check

Pump the brake pedal several times to ensure the pads are properly seated against the rotors.
Check brake fluid level and top off if necessary.
