Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect brake pads for wear indicators; if they are worn down to the metal, they must be replaced.
Use a C-clamp to compress the caliper piston if replacing pads.
Remove the caliper bolts with a socket set and slide off the caliper.
Replace the old pads with new ones, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or excessive wear; if damaged, they should be replaced.
Remove the rotor by taking off the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and correctly aligned with the hub.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and secure it with the caliper bolts.
Reattach the wheel and tighten the lug nuts to the manufacturer's specified torque.
Lower the vehicle back to the ground.

6. Brake Fluid Check

Inspect brake fluid level and top it off if necessary with the appropriate fluid type.
Check for any leaks in the brake lines.
